Thelma L. P. Dias, Ierecê L. Rosa & Bertran M. Feitoza: Food Resource and Habitat Sharing by the three Western South Atlantic Surgeonfishes (Teleostei: Acanthuridae: Acanthurus) off Paraiba Coast, North-eastern Brazil, pp. 1-10

Diet and feeding  behaviour of the three western South Atlantic acanthurids (Acanthurus bahianus, A. chirugus, and A. coeruleus) were analysed, based on stomach contents analysis and underwater observations. Data ere obtained at three natural reefs and two shipwrecks along the coast of Paraíba State, NE Brazil. The results of Schoener÷s Index suggest that dietary overlap was not significant between species pairs; however, some degree of microhabitat segregation was observed. Juveniles of A. bahianus and A. chirurgus formed feeding aggregations, whereas juveniles of A. coeruleus foraged solitarily. Adults of the three studied species formed intra- or interspecific feeding groups. Following behaviour was observed between acanthurids and Halichoeres spp., Pseudupeeus maculates, and Sparisoma spp.

Alexei M. Orlov, Alexei M. Tokranov, and Andrei V. Vinnikov: Additional records of scaled scuplin Archaulus biseriatus Gilbert & Burke, 1912 (Cottidae, Teleostei) from the North Pacific, pp. 11-18

The scaled sculpin Archaulus biseriatus gilbert & Burke, 1912 is reported from three new North Pacific records from off the northern Kuril Islands, Russia, and the central Aleutian Islands, Alaska, north of Seguam Island. This species was previously known from the type series from the Aleutian Islands, Petrel Bank in the southern Bering Sea, ad a recent report and redescription of a single specimen from the central Kuril Archipelago off Simushir Island (Yabe and Soma, 2000). Additional records from the northern Kuril Islands and the eastern Aleutian Islands north of Seguam Island are also reported. Notes on the morphology, habitat, and species associations of Archaulus are presented, and photographs of specimens are provided.

Richard Winterbottom: Two new gobiid fish species in Trimma and Trimmatom from the Indian and Western Pacific Oceans, pp. 19-24

Two new gobiid fish species are described. Trimma stobbsi has no scales in the predorsal midline, a slight interorbital trench, unbranched fifth pelvic fin ray, and a distinct dark spot above und just anterior to the posterodorsal corner of the operculum. Trimmatom pharus has a scaled body, a reduced (20% or less of the length of fourth ray) and unbranched fifth pelvic fin ray, and the first four pelvic fin rays branched. Numerous dark bars (red in life) are present on head and body. Trimmatom pharus is considered to be part of the T. eviotops species group. Both new species are found in the Indian and western Pacific Oceans.

William F. Smith-Vaniz, Ukkrit Satapoomin, and Gerald R. Allen: Meiacanthus urostigma, a New Fangblenny from the Northeastern Indian Ocean, with Discussion and Examples of Mimicry in Species of Meiacanthus (Teleostei: Blenniidae: Nemophini), pp. 25-43

The 3 subgenera and 25 species of Indo-Pacific blenniid fishes of the fangblenny genus Meiacanthus are differentiated in a key. Meiacanthus urostigma, new species, is described from the Surin Islands and northern Sumatra. This region of the Indian Ocean appears to be a localized area of endemism, attributable to glacial sea-level lowering events. The new species is distinguished from its congeners by its colour pattern characterized by a uniformly pale tan body with a narrow dark lateral stripe extending from the snout to near the beginning of the bright orange-yellow caudal peduncle where it is typically interrupted and replaced by an elongate black spot. The new species is the second known member of the subgenus Allomeiacanthus (type species Meiacanthus ditrema Smith-Vaniz). This subgenus differs from the other subgenera most notably in having a toxic buccal gland that is ventrally positioned and encapsulated by the dentary bone, absence of a lateral line, and only 2 pores (3 in the other subgenera) in the mandibular and posttemporal series. Juveniles of the new species appear to be social mimics of similar-sized individuals of the cardinalfish Cheilodipterus qunquelineatus. Mimetic relationships involving species of Meiacanthus are discussed and colour photographs are given of selected mimetic pairs.

Volume 5, Issue 2 - February 2002

Richard Winderbottom: Two new species of Trimma (Gobiidae) from the central, wester, and south Pacific, pp. 45-52

Two new species of the genus Trimma are described. Trimma milta n. sp. is characterized by the presence of scales in the predorsal midline, an unbranched fifth pelvic fin rays which is about half the length of the fourth rays, a lack of elongate spines in the first dorsal fin, a red-brown or yellowish coloration, usually with the scale pockets clearly outlined with melanophores and chromatophores, and, at least in adults, two to three scales on the upper portion of the opercle. Trimma woutsi is distinguished by a white saddle along the dorsal margin of the pectoral base, large irregular spots on the head and body, an elongate dorsal spine, no predorsal scales, and a fifth pelvic fin ray which branches dichotomously 2-3 times.

Ukkrit Satapoomin and Richard Winterbottom: Redescription of the Gobioid Fish Cryptocentrus pavoninoides (Bleeker, 1849), with Notes on Sexual Dichromatism in Shrimp Gobies, pp. 53-64

Cryptocentrus pavoninoides (Bleeker, 1849), a little known gobioid species, is redescribed in detail from the holotype and eleven additional specimens collected from the Gulf of Thailand, Singapore, and southwestern Thailand (Andaman Sea). The species is characterized by two to five ovoid black spots between the first to sixth spines at the mid-height of the first dorsal fin, distinctive black pelvic fins, and blue spots on head. It exhibits sexual dichromatism in which the males have a brownish body background with three vague darker bars and scattered blue spots; while the females possess a yellow body background with 8-10 distinct brow bars and without blue spots along sides of the body. Sexual dichromatism in several other species of shrimp gobies is documented.

Gerald R. Allen and D. Ross Robertson: Halichoeres salmofasciatus, a new species of wrasse (Pisces: Labridae) from Isla del Coco, tropical eastern Pacific, pp. 65-72

Halichoeres salmofasciatus, n. sp., is described from 23 specimens, 28.5-62.9 mm SL, collected at Isla del Coco, Costa Rica, in 1997. Among the 12 other known species of this genus in the tropical eastern Pacific it appears to be most closely related to H. malpelo and H. melanotis, but differs from both those species in maximum size, colour pattern, and certain meristics. The terminal phase adult of H. salmofasciatus has an olive back, an indistinct dark olive stripe along the body at eye level, and a pale orange tail with a broad, grey terminal edge. The initial phase adult of H. salmofasiatus in pale grey and white with two salmon red stripes running along the length of the body (one at eye level and a narrower one along the upper black), two black spots within the midlateral stripe (one on the opercular membrane, the other on the caudal peduncle), and a pale orange tail.

Bertran M. Feitoza, Thelma L. P. Dias, Luiz A. Rocha, and João Luiz Gasparini: First records of cleaning activity in the slippery dick, Halichoeres bivittatus (Perciformes: Labridae), off northeastern Brazil, pp. 73-76

Cleaing behaviour is reported in Halichoeres bivittatus for the first time, off Paraíba coast, northeastern Brazil. Six species of clients were cleaned by one to three cleaners, similar in size, in one of two ways: stationary at a cleaning station or whilst swimming over a relatively large area. In each situation, the cleaning events lasted from 2 to 5 seconds. Following behaviour associated with mobile cleaning events was observed and the two activities seem to be related. On the basis of our observations of Halichoeres bivittatus, we consider this labrid to be a ”substrate picker’, a non-specialized form of cleaner fish.

John E. Randall, Robert F. Myers, and Richard Winterbottom: Melichthys indicus x M. vidua, a hybrid triggerfish (Tetraodontiformes: Balistidae) from Indonesia, pp. 77-80

The hybrid of the triggerfishes Melichthys indicus and M. viduai is reported from two underwater photographs taken at Bali, Indonesia and a single specimen collected in the Chagos Archipelago. This constitutes the first record of a hybrid for the family Balistidae.

Daphne J. Martin: fish Consumption in a midieval English bishop's household, 1406-7, pp. 81-88

The accounts of a fifteeth-century English bishop give details of the fish eaten in is Wiltshire household on meatless days, comprising twenty-five species of fish, and seven types of crustaceans and gastropods. This reflects the advances in ship building and fishing methods. The servants were fed imported smoked and pickled North Sea herring, ad salted and dried Icelandic cod, supplied by the Hanseatic league of German ports. The bishop, his guests and household officials ate a variety of fresh marine and freshwater species, caught in the English Channel and Severn estuary and in local rivers. The daily fish ration was 0.5-1 kg and the total annual cost of the fish was nearly 5% of the bishop÷s income.

Alexei M. Orlov, Alexei M. Tokranov and Igor A. Biryukov: New records of rex sole Glyptocephalus zachirus Lockington, 1879 (Teleostei: Pleuronectidae) from the north-western Pacific, pp. 89-98

The rex sole Glyptocephalus zachirus Lockinghton, 1879 is reported from eighteen new north-western Pacific records from off he northern Kuril Islands and south-eastern Kamchatka, Russia. This species ad been previously recorded in this area only once (Tokranova and Vinnikov, 2000), from near the tip of the Kamchatka peninsula. We report additional records here from the northern Kuril Islands and south-eastern Kamchatka. One of them represents a significant range extension of about 360 km for the species. Notes on the habitat and species associations of rex sole are presented, with a photograph of one specimens. 

James Wilder Orr, Ronald Alan Fitzsche, and John Ernest Randall:  Solenostomus halimeda, a New Species of Ghost Pipefish (Teleostei: Gasterosteiformes) from the Indo-Pacific, with a Revised Key to the known species of the Family Solenostomidae, pp. 99-108

Solenostomus halimeda is described as a new species of the solenostomidae, the ghost pipefishes, from specimens collected from the Maldives, western Australia, Papua New Guinea, and the Mariana Islands. The new species differs from all other solenostomids in the length of its spinous dorsal pelvic, and caudal fins, its truncate caudal fin, lower dorsal and anal fin ray counts, and small size at sexual maturity. Solenostomus halimeda is most similar to S. cyanopterus, from which it also differs in its more slender snout, absence of a premaxillary spine in males, and presence of abdominal prickles. Unlike S. paradoxus, S. halimeda possesses multifid dermal papillae, nasal lamellae of males that fill only half the olfactory pit, and a reduced supraoccipital ridge. Unlike S. armatus, the new species ha a reduced supraoccipital ridge and a more robust body, and females have a small dorsal patch of nasal lamellae and a convex pelvic fin margin. A revised key to adults of the family, and colour photographs of Solenostomus halimeda, S. paradoxus, S. cyanopterus  and a diagram of S. armatus are provided.

Gerald R. Allen and John E. Randall: A new species of Wrasse (Labridae:  Choerodon) from the Tropical Western Pacific, pp. 109-113

Choerodon gomoni is described from six specimens, 86.1-103.9 mm SL, from the Chesterfield Bank, Coral Sea and the Banggai Islands, Indonesia. It belogs to the Peaolopesia ”complex’ of species that includes C. sugilltum (northern Australia), C. margaritiferus (Philippines), C. japonicus (Taiwan and Japan), C. gymnogenys (East Africa), and another undescribed East African species. The members of this complex are morphologically similar and best separated on the basis of colour pattern. Choerodon gomoni is distinguished by its male and female colour patterns. The male pattern, which includes a large reddish spot on the middle of the back and a pale yellow lateral stripe, is particularly distinctive.

Gerald R. Allen and John E. Randall: Four new Indo-Pacific species of cardinalfishes (Apogonidae), pp. 115-126

The following four Indo-Pacific cardinalfishes of the genus Apogon are described as new. A. lineomaculatus from Bali and Flores, Indonesia from 8-32 m (usually over 18 m) is distinct in having 15 pectoral rays, 4 predorsal scales, 5 + 18-20 developed gill rakers, a narrow mid-lateral black stripe ending in a large black spot at caudal fin base, a black blotch above anal fin base, and numerous faint narrow blackish bars on lower side; A. microspilos, described from two specimens taken in 21.5 m off Lombok, Indonesia, has 13 pectoral rays, 3 median predorsal scales, 3-5 + 14-15 devoloped gill rakers, and is orange-red in life with a very small dark spot at mid-base of caudal fin; A. cladophilos, described from six specimens taken in 20 m at Lizard Island on the Great Barrier Reef but also photographed in Flores (at both localities in association with soft corals), has 14 pectoral rays, 4 median predorsal scales, 4-5 + 16-17 developed gill rakers, a thin dark mid-lateral stripe and a pupil-size black spot at caudal fi base; ad A. posterofasciatus, described from three specimens from the Solomon Islands, Flores, and Philippines at depths of 18-37 m and distinguished by VI dorsal spines (the above three species with VII), 6 predorsal scales, 2 + 11 developed gill rakers, a membranous flap at the angle of the preopercle, and two dusky bars posteriorly on body, one below rear base of second dorsal fin and one at base of caudal fin.

Ivan Sazima, João Luiz Gasparini and Rodrigo Leão de Moura: Labrisomus cricota, a new scaled blenny from the coast of Brazil (Perciformes: Labrisomidae), pp. 127-132

Labrisomus cricota, a scaled blenny from the coast of Brazil, is described. The new species differs from its nine West Atlantic congeners by the combination of the following characters: opercle with a dark ocellus, 64 to 68 lateral line scales, first and second dorsal fin spines noticeably longer than the third, and not flexible.

Volume 5, Issue 4 - July 2002

Arturo Acero P. and Richardo Betancur-R: Arius cookei, a new species of ariid catfish from the tropical American Pacific, pp. 133-138

A new species of sea catfish (family Ariidae) from the tropical eastern Pacific, Arius cookie n. sp., is described. It can be easily separated from other western American ariid species by its elongated supraoccipital process, which is 1.5 to 1.7 times longer than the width of its base (in specimens over 343 mm SL). The species is known from fresh and brackish waters from Costa Rica to Colombia.

Gerald R. Allen and John E. Randall: A review of the leucogaster species complex of the Indo-pacific pomacentrid genus Amblyglyphidodon, with descriptions of two new species, pp. 139-152

The Indo-Pacific pomacentrid Amblyglyphidon leucogaster was previously thought to consist of several distinct geographic colour variations. However, the present study indicated there is a complex of four species: A. leucogaster (Bleeker) from the western Pacific and eastern edge of the Indian Ocean, A. orbicularis (Hombron & Jacqinot) from Samoa, Fiji, and New Caledonia, and two new species described herein – A. indicus from the Red Sea and Indian Ocean, and A. melanopterus from Tonga. The members of the leucogaster complex are mainly differentiated by a combination of colour pattern and gill-raker counts. A key to the species of Amblyglyhidon is included.

John E. Randall: Two new damselfishes of the genus Pomacentrus from the south-west Pacific, pp. 167-176

Pomacentrus callainus, formely identified as a colour variety of the western Pacific P. lepidogenys, is described from specimens from Tonga and Fiji. It is distinct from P. lepidogenys in its overall blue-green colour with a wedge-shaped black spot at the upper base of the pectoral fin, higher gill raker counts (22-25, compared to 20-23 for P. lepidogeys), deeper body (47.5-51% SL compared to 43.5-47% SL, for P. lepidogenys), longer dorsal spines (longest spine 14.7-17.1% SL, compared to 12.7-14.7% SL in P. lepidogenys), and probable larger size. Pomacentrus spilotoceps is described as new from four specimens from Tonga and underwater photographs from Fiji. Its closest relative appears to be P. chrysurus, known from the western Pacific to the Maldive Islands. P. spilotoces differs in having in orange or yellow spots on the operculum and before and above the base of the pectoral fins and 22-24 gill rakers, compared with 18-19 for P. chrysurus).

John E. Randall and Bruce A. Carlson: The Pygmy Angelfish Centropyge woodheadi Kuiter, 1998, a Synonym of C. heraldi Woods and Schultz, 1953, pp. 1-4

¬ÝCentropyge woodheadi Kuiter, 1998 is regarded as e junior synonym of C. heraldi Woods and Schultz, 1593. the 4 measurements reported to differntiate woodheadi from heraldi could not be duplicated by taking the same measurements of 7 specimens of the woodheadi¬Ý form and 18 typical C. hearldi of about the same range in standard length. The woodheadi form has been observed to lose the diagnostic broad black band in the soft prtion of the dorsal fin in an aquarium. In addition to records of the woodheadi form from Samoa, Fiji, Tonga, Coral Sea, and Solomon Islands, one specimen is reported from Huahine, Society Islands, and one from Kwajalein Atoll, Marshall Islands.

Ronald E. Watson, Gerard Marquet and Christine Pollabauer: New Caledonia Fish Species of the genus Sicyopterus (Teleostei: Gobiodei: Sicydiinae), pp. 5-34

¬ÝSicyopterus Gill from New Caledonia is Reviewed and the genus is diagnosed. Sicyopterus lacogephalus (Pallas) has a wide geographic distribution: it occurs in streams on the Comoro and Mascarene Islands in the western Indian Ocean; on society Islands in the central Pacific and is known to extend from New Caledonia to southern Japan. Sicyopterus lacogephalus is distinguished from its congeners by 11 segmented rays in the second dorsal fin and by the following combination of characters: usually 9 (17-22) pectoral rays; scales in predorsal midline usually 13-16 (11-20) with anterior scales smaller than those posteriorly; scales in lateral series usually 51-54 (49-59); scales on trunk and belly about same size as on caudal peduncle; transverse forward scales usually 18; ventral edge of upper lip usually smooth with clefts anteriorly and midlaterally; and caudal fin with a blackish horseshoe-shaped band close to margin and medial rays dusky to blackish usually extending to horseshoe-shaped band. No type is known to exist and for this reason a neotype for Gobius lagocephalus is designated. Sicyopterus sarasini Weber & de Beaufort is an uncommon New Caledonia endemic. It is distinguished from all congeners by the presence of 10 segmented rays in the second dorsal fin and by the following combination of characters: usually 19 pectoral rays; scales in predorsal midline small, cycloid and variable (0-26); scales I lateral series 45-65, with scales on flanks much smaller than those on caudal peduncle which may be widely separated; transverse forward scales variable, with ventral scales small (14-31); scales o belly much smaller than on caudal peduncle and belly may be fully scald or entirely naked; ventral edge of upper lip usually with some crenulation and clefts anteriorly and midlaterally. Males of S. sarasii differ from congeners with clefts present anteriorly and midlaterally in upper lip, in not hving scales embedded anteriorly or covered marginally with spongy tissue. A lectotype for Sicyopterus sarasini is designated from the original syntype series.

Igor V. Mitrofanov: The Biodiversity of the genus Leuciscus in Central Asia (Cyprinidae), pp. 35-43

Data published since the beginning of the 20th century on 64 populations of dace from Europe, Central Asia, Kazakhstan, and Siberia were analyzed. Four discriminant meristic characters used previously to identify species and subspecies were utilized in this study. Cluster and Principal Component analyses used to assess similarities and differences in the dace populations suggest that all dace populations of Kazakhstan and Central Asia appear to form a linear continuum of relationships. Most populations within the distribution of each species or subspecies of this continuum are similar, however there is at least one population that is similar to another species or subspecies. It is our opinion that all of the populations of dace from Kazakhstan (excluding those of the Ural Basin) and Central Asia belong to one polytypic species.

Volume 4, Issue 2 - December 2000

Gerald R. Allen: Description of a New Wrasse (Pisces: Labridae: Cirrhilabrus) from Northern Sumatra, Indonesia, pp. 45-50

Cirrhhilabrus joanallenae, new species is described from 3 specimens, 41.2-46.2 mm SL, collected at Weh Island, northern Sumatra. It is closely allied to C. rubriventralis from the W. Indian Ocean Red Sea, both species exhibiting an elevated ”pennant’ at the beginning of the dorsal fin, large club-shaped pelvic fins, and a single row of scales on the cheek. However, the new species differs in life colours of male and females, in having fewer scales on the cheek, less conspicuous serrations on the preopercular margin, and 15-16 rather than 14 pectoral rays.

John E. Randall and Joachim Frische: Hybrid Surgeonfishes of the Acanthurus achilles Complex, pp. 51-56

Three hybrids are known among the four species of surgeonfishes that comprise the Acanthurus achilles complex: A. achilles x A. nigricans (documented by Randall, 1956a); A. leucosternon x A. nigricans (previously known from an aquarium photograph, 1982, here reported from a specimen from Indonesia); and A. japonicus x A. nigricans (based on an underwater photograph from Lanyu, Taiwan).

Richard Winterbottom: Four new species of Trimma (Gobiidae), from the Indian and Western Pacific Oceans, pp. 57-66

Four new species of the genus Trimma are described: Trimma anaima is a small species found in both Indian and western Pacific oceans. Trimma anaima has no scales in the predorsal midline, no interorbital or postorbital trenches, unbranched fifth pelvic fin-ray, and four small dark saddles over the dorsal midline. Trimma bisella, to date found only at Mauritius, has no scales in the predorsal midline, an interorbital trench, unbranched fifth pelvic fin ray, and two white saddles on the caudal peduncle. Trimma halonevum has predorsal scales, a moderate and steep-sided interorbital trench, and a fifth pelvic fin ray with a single dichotomous branch. It is salmon-coloured with red-brown and yellow spots on the head and body. Trimma halonevum has a wide distribution in the western Pacific ad has been found in the Indian Ocean at Christmas Island and the Maldives. Trimma omanensis has a crescent-shaped bar on the posterior edge of the pectoral base, head and predorsal midline naked, well-developed interorbital and postorbital trenches, a fifth pelvic fin ray which branches twice, and has to date only been found in the Gulf of Oman.

J. B. Heiser, R. L. Moura, and D. R. Roberson: Two new species of Creole Wrasse (Labridae: Clepticus) from opposite sides of the Atlantic, pp. 67-76

Two new species of labrid are described, one each from the eastern and western sides of the equatorial Atlantic. Clepticus africanus, n. sp., is described from fourteen specimens collected from São Tomé Island in the Gulf of Guinea off the equatorial African coast. Clepticus brasiliensis, n. sp., is described from nine-teen specimens (plus additional material) collected from the coast and offshore islands of Brazil south of the Amazon. Neither species is significantly different in morphometric or meristic characters from the heretofore sole member of the genus, the tropical western North Atlantic Clepticus parrae. Both new specis are distinguished from C. parrae. Both new species are distinguished from C. parrae by coloration and by the development in adults of greatly extended fin rays (two-thirds the standard length) from the tips of the upper and lower lobes of the forked caudal fin: the mostly balck African creole Wrasse with one filament on each lobe of the caudal, and the mostly mauve to purple Brazilian Creole Wrasse with two or more such filaments. The two new specis represent a pair of amphi-Atlatic sister taxa.

Gavin D. Alexander and Colin E. Adams: The phenotypic diversity of Arctic charr, Salvelinus alpinus, (Salmonidae) in Scotland and Ireland, pp. 77-88

The high phenotypic variability of Arctic charr and the nature of polymorphism in the species are briefly summarized. Photographs of Arctic charr from populations in Scotland and Republic of Irelad are presented to illustrate some of the phenotypic diversity of the species in these two countries.

John E. Randall and Richard L. Pyle: Three New Species of Labrid Fishes of the Genus Cirrhilabrus from the Islands of the Tropical Pacific, pp. 89-98

¬ÝThe following three new wrasses of the genus Cirrhilabrus are described from islands of the central and western Pacific: C. claire, from two specimens, an 84.0 mm male and a 72.8 mm female taken in 92 m off Rarotonga, Cook Islands; C. earlei from nine specimens, 45.1-69.1 mm, collected in 80-92 m from Palau; and C. walshi from two male specimens, 56.0-62.8 mm, from 37-46 m off Taumu Bank, Tutuila, American Samoa. Colour illustrations are presented, and comparisons are made with similar species.

Eugenio Alberto Aragón-Noriega and Luis Eduardo Calderon-Aguilera: Age and growth of shrimp (Decapoda: Penaeidae) postlarvae in the Upper Gulf of California, pp. 99-104

Postlarvae are a critical stage in the life cycle of the shrimp because catches depend on the strength of this year class. To assess the growth of postlarvae in the upper Gulf of California, intensive sampling was performed during a complete tide cycle from July 12-27, 1995 and from June 30 to July 16, 1996, simultaneously in two locations: one off the mainland (Santa Clara) and one off the peninsula (San Felipe). A 10-minute trawl was performed every hour during the flood tide (day and night). The total length of each individual postlarva was determined by measuring it with the aid of a calibrated micrometer (0.001 mm). Two species were found: Farfantepenaeus californiensis and Litopenaeus stylirostris, known as brown and blue shrimp, respectively. Subsequently these two species were reared to assess their age from their length. Wild postlarvae range from 7 to 13 mm and average 9 mm. It was concluded that wild postlarvae are recruited to the upper Gulf of California 20 to 28 days after being spawned in oceanic waters.

Luiz A. Rocha, Richardo Z. P. Guimarães, and João L. Gasparini: Redescription of the Brazilian Wrasse Thalassoma noronhanum (Boulenger, 1890) (Teleostei: Labridae), pp. 105-108

Thalassoma noronhanum is a poorly known wrasse that inhabits tropical reefs of the western South Atlantic. The species is found from Parcel de Manuel Luiz reefs to the coast of São Paulo, and at all Brazilian oceanic islands. It inhabits rocky and coralline algae reefs, and was collected from the shoreline to depths of 60 m. Juveniles are known to clean other fish, and adult females form harems dominated by a few terminal-phase males.

João Luiz Gasparini, Luiz A. Rocha, and Sergio R. Floeter:  Ptereleotris randalli n. sp., a new dartfish (Gobioidei: Microdesmidae) from the Brazilian Coast, pp. 109-114

Ptereleotris randalli n. sp., the third species of the genus from the Western Atlantic, is described from the Brazilian Coast. It differs from P. helenae, its North Atlantic sister species, in having the second dorsal and anal fins comparatively lower and slightly more elevated anteriorly; a shorter caudal fin with the fifth and sixth rays prolonged as filaments; and shorter pelvic fins which are about the same length as the pectorals. This species is known from Parcel de Manuel Luiz (00°52÷S, 44°16÷W), NE Brazil to Alcatrazes Archipelago (24°06÷S, 45°42÷W), SE Brazil, in depths between 8 and 60 m.

John E. Randall, Richard L. Pyle, and Robert F. Myers: Three Examples of Hybrid Surgeonfishes (Acanthuridae), pp. 115-120

Three hybrids of surgeonfishes (Acanthuridae) are documented: Acanthurus nigricauda x A. olivaceus from the Marshall Islands, A. olivaceus x A. tennentii from Bali, Indonesia, and Zebrasoma rostratum x Z. scopas from Kiritimati (formerly Christmas Island), Line Islands.

Gerald R. Allen: Lentipes multiradiatus, a New Species of Freshwater Goby (Gobiidae) from Irian Jaya, Indonesia, pp. 121-124

A new species of freshwater gobiid, Lentipes multiradiatus, is described on the basis of a single male specimen, 27.4 mm SL, collected from the Cyclops coast, near Jayapura, Irian Jaya Province, Indonesia. The species is characterised by a combination of features that include: dorsal rays VI-I,10;  anal rays I,10; pectoral rays 20; first dorsal fin connected basally to second dorsal fin; four oculoscapular sensory pores; and the absence of both bilobed urogenital structures and a sac of replacement teeth on the upper jaw. It is the only species of Lentipes, except for L. watsoni from southern Papua New Guinea, in which males possess a small black spot at the beginning of the second dorsal fin.

Volume 4, Issue 4 - August 2001

Gerald R. Allen: Description of Two New Gobies (Eviota, Gobiidae) from Indonesian Seas, pp. 125-130

Two new species of Gobiidae are described from Indonesia. Eviota raja is described from 16 specimens, 12.7-23.8 mm SL, collected at the Raja Ampat Islands, Irian Jaya Province. It is closely related to E. bifasciata, a sympatric species that is distributed across the Indo-Australia Archipelago. The two species differ in colour pattern, as well as counts for segmented rays in the second dorsal fin and lateral scale rows (usually 9 and 22 respectively for E. bifasciata and 10 and 25 in E. raja). The second new species, Eviota mikiae, is described on the basis of 9 specimens, 12.6-19.1 mm SL, collected at Pulau Weh, northern Sumatra. It is similar in appearance to E. pellucida of the western Pacific, but differs in having more segmented rays in the second dorsal fin, (9 versus a usual count of 8), more branches on the fourth pelvic fin ray (modally 8 versus 5), ad fewer segments between branches on the fourth pelvic fin ay (1 versus 5).

John E. Randall and Aharon Miroz: Thalassoma lunare x Thalassoma ruepellii, A Hybrid Labrid Fish from the Red Sea, pp. 131-134

A hybrid of the endemic Red Sea labrid fish Thalassoma ruepellii (Klunzinger) (identified as T. klunzingeri Flower and Steinitz by most recent authors) and the wide-ranging Indo-Pacific T. lunare (Linaeus) is documented. Colour illustrations of the hybrid, the parent species, and the young and subadult of T. rueppellii are presented. The hybrid specimen (BPBM 38478, 247 mm SL) is deposited in the Bishop Museum, Honolulu, Hawaii.

Shelley Walker and Francisco J. Neira: Aspects of the reproductive biology and early life history of black bream, Acanthopagrus butcheri (Sparidae), in a brackish lagoon system in southeastern Australia, pp. 135-142

Aspects of the reproductive biology and early life history of black bream (Acanthopagrus butcheri) in the Gippsland Lakes, a large brackish lagoon system in southeastern Australia, are described. Trends in mean gonadosomatic indices of males and females between November 1993 and March 1996 indicate that spawning occurred between October and February, with a peak in October-November when water temperatures were 15-22°C. Larvae (4.6-11.2 mm body length (BL)) were caught in shallow brackish ponds in November 1996 ad January 1997 and possess the typical sparid characteristics. Notochord flexion in larvae occurs at 4.6-6.0 mm BL, while early juveniles settle from about 13 mm BL. Ageing of black bream showed that the youngest sexually mature male (15.6 cm fork length (FL)) and female (15.9 cm FL) were 3+ year olds. The ability of black bream to complete their life cycle within estuarine environments appears to be unique amongst members of the Sparidae worldwide.

Gerald R. Allen: Two New Species of Cardinalfishes (Apogonidae) from the Raja Ampat Islands, Indonesia, pp. 143-149

Two new species of apogonid fishes are described from the Raja Ampat Islands, off western New Guinea (Indonesian province of Irian Jaya), based on specimens collected during a Conservation International Survey in March-April 2001. Apogon leptofasciatus is described from three specimens, 48.2-50 mm SL, collected from a depth of 15 m. It is most similar to A. nigrocinctus Smith and Radcliffe (northern Australia to the Philippines) and A. jenkinsi Evermann and Seale (Australia to Japan), both of which possess similar black markings on the dorsal fins and caudal fin base. However, adults of these species lack narrow stripes on the upper body, and A. jenkinsi also differs in having a black spot on each side of the nape. The new species further differs from these two species in having fewer developed rakers on the first branchial arch (18 versus 22-25). Apogon oxygrammus is described on the basis of three specimens, 30.8-38.7 mm SL, collected from a depth of 46 m. It differs from all known species in the genus on the basis of colour pattern (overall whitish with a tapering black mid-lateral stripe that extends onto the caudal fin) and jaw dentition (enlarged teeth in relatively few rows).

Victor G. Springer and Gerald R. Allen: Ecsenius ops, from Indonesia, and E. tricolor, from Western Philippines and Northwestern Kalimantan, New species of Blenniid Fishes in the Stigmatura Species Group, pp. 151-160

Based on additional material and numerous colour photographs taken in the field, Ecsenius melarchus, as treated by springer (1988), is shown to comprise three species, two of which are described as new. We hypothesize that six species within Ecsenius (E. stigmatura, E. melarchus, E. ops n. sp, E. tricolor n. sp., E. midas, and E. lividanalis) form a monophyletic clade, the Stigmatura species group. We further hypothesize that the Bicolor species group (E. bicolor, E. namiyei) is the sister group of the Stigmatura group. The Stigmatura group comprises a trichotomy of two monospecific branches and the Stigmatura complex, which comprises an unresolved polytomy of E. melarchus, E. stigmatura, E. ops, and E. tricolor. Aspects of the distribution of the Stigmatura complex species are discussed with regard to Huxley÷s Line.

Luiz A. Rocha and Ricardo S. Rosa: Halichoeres brasiliensis (Bloch, 1791), a valid wrasse species (Teleostei: Labridae) from Brazil, with notes on the Caribbean species Halichoeres radiatus (Linnaeus, 1758), pp. 161-166

Halichoeres brasiliensis (Bloch, 1791), previously considered to be a junior synonym of H. radiatus (Linnaeus, 1758), is a valid species. It differs from H. radiatus by having 19-21 instead of 21-23 gill rakers, lacking four whitish blotches on the dorsum, and having a blue instead of a yellow margin on the caudal fin. The two species have allopatric distributions: H. brasiliensis is found on the Brazilian continental shelf and at Trindade Island, whereas the range of H. radiatus comprises the Caribbean, Gulf of Mexico, Florida, Bermuda, and the Brazilian oceanic islands of Fernando de Noronha, Atol das Rocas, and St. Paul÷s Rocks.

Gerald R. Allen, Walter Ivantsoff, Margaret A. Shephert and Samuel J. Renyaan:¬Ý Pseudomugil pellucidus (Pisces: Pseudomugilidae), a newly discovered blue-eye from Timika-Tembagapura region, Irian Jaya, pp. 1-8

Pseudomugil pellucidus, a new species of blue-eyes, is described on the basis of 30 specimens collected from tributaries of the Iweka and Kopi rivers in the vicinity of Tembagapura, Irian Jaya. The new species is very closely related to P. novaeguinaeae but is distinct from the latter on the basis of greater number and length of first dorsal fin spines, number of anal rays, shape of vomer, basibranchials, pectoral girdle, urohyal, and anal pterygiophores. The new species is different in coloration; and is also quite transparent.

Gerald R. Allen and M. N. Feinberg: Descriptions of a New Genus and Four New Species of Freshwater Catfishes (Plotosidae) from Australia, pp. 9-18

¬ÝA new genus and four new species of plostosid catfishes are described from frsh waters of Australia. Neosiluroides, new genus, differs from all other plotosid genera by the possession of two, apparently derived, characters, namely a thick epidermal covering around the posterior nostril, which forms an outer chamber, and a peculiar ski structure, consisting of a dense covering of minute papillae. In addition, it is separable from nearly all other Australiana and New ginean freshwater catfishes by its high vertebral count. The genus contains a single member,¬Ý N. cooperensis, new species, which is described from 32 specimens, 167-346.5 mm SL, from the Cooper Creek system of north-eastern South Australia and adjacent south-western Queensland. Neosilurus gloveri, new species, is described from 64 specimens, 36-84 mm SL, collected from warm artesian pools at Dalhousie Sprigs in the desert of northern South Australia. It grows to a maximum size of about 84 mm SL. It is the smallest member of the family and is further characterized by 38-42 total vertebrae, 14-16 total gill rakers on the first branchial arch, 7-9 soft pectoral rays, and 7-8 branchiostegal rays. Neosilurus pseudospinosus, new species, is described from 279 specimens, 24-333 mm SL, collected from the Kimberley region of north-western Australia. It is closely related to N. mollespiculum,¬Ý new species, which is described from 11 specimens, 39-345 mm SL, collected from the Burdeki River system of north-eastern Queensland. Both resemble N. ater or northern Australia and southern New Guinea, but differ in having lower gill raker counts and soft, flexible dorsal and pectoral fin spines. N. pseudospinosus differs from¬Ý N. mollespiculum primarly in having a greaer average umber of procurret caudal rays, a slightly shorter dorsal-caudal fin base, and a longer nasal barberl.

Victor G. Springer, Hans Bath and John E. Randall: Remarks on the species of the Indian Ocean Fish Genus Alloblennius Smith-Vaniz & Springer 1971, (Blenniidae), pp. 19-24

Females of Alloblennius anuchalis (Springer & spreitzer, 1978), previously known only from the male hototype, are described and illustrated. Thez differ from the male, and both sexes of the three other Alloblennius species, in having alternating dark and pale bands in the anal fin. Geographic range extensions are noted for A. anchalis, A. parvus, and A. pictus. Males of A. parvus from Mauritius, but not Comores, have statistically significantly higher mean numbers of segmented dorsal- and anal-fin rays, and caudal vertebrae, than do females from their respective localities. Colour photographs of all four Alloblennius species are included.

John E. Randall: Review of the Cardinalfishes (Apogonidae) of the Hawaiian Islands, with descriptions of two new species, pp. 25-38

The 10 species of apogonid fishes of the Hawaiian Islands are differentiated in a key. Paseudamiops diaphanes, sp. n., endemic to Hawaii, is distinct in having VI-I,8 dorsal rays, II,8 anal rays, 16-18 pectoral rays, a spine-like ventral projection posteriorly on the maxilla, deciduous cycloid scales, no lateral line, a rhomboid caudal fin, and in being transparent in life. Apogon deetsie, sp. n., from the Hawaiian Islands and Tuamotu Archipelago, has VI-I,9 dorsal rays, II,8 anal rays; 11-12 (usually 12) pectoral rays, 24 lateral-line scales, 6 predorsal scales, 3-4 + 12-13 gill rakers, a protruding membranous flap on corner and lower edge of preopercle, a forked caudal fin with rounded lobes, and is light red with two blackish bars posteriorly on the body. The remaining species are diagnosed, and their distributions given, Apogon erythrinus Snyder appears to be endemic to Hawaii and Johnston Island; A. maculiferus Garrett is also a Hawaiian endemic; A. evermanni Jordan and Snyder is widespread in the Indo-Pacific and is also known from the western Atlantic; A. kallopterus Bleeker, A. taeniopterus Bennett (A. menesemus Jenkins is a synonym), Apogonichthys perdix Bleeker (A. waikiki Jordan and Evermann is a synonym), Foa brachygramma (Jenkins), and Lachnearatus phasmaticus Fraser and Struhsaker are wide-ranging Indo-Pacific species.

Ivan Sazima, João Luiz Gasparini and Rodrigo L. Mourra: Gramma brasiliensis, a new basslet from the western South Atlantic (Perciformes: Grammatidae), pp. 39-43

¬ÝThe basslet Gramma brasiliensis sp. n. is described from the coast of Brazil. The new species differs from its congeners by the combination of the following characters: upper jaw extending a distance of about one pupil diameter beyond rear margin of eye, first dorsal-fin spine noticeably shorter than the remainder, life color of anterior part of body purple to violet and posterior part yellow to orange, yellow streaks on head absent. Gramma brasiliensis sp. n. represents the southernmost record for this genus.

Uwe Romer and Frank Warzel: Apistogramma arua sp. n. (Teleostei: perciformes: Cichlidae), a new species of dwarf cichlid from the Rio Arapiuns system, Para State, Brazil, pp. 45-44

Apistogramma arua sp. n. is described on the basis of four specimens collected in a small igarapé near Arua in the lower course of the Rio Arua. This relatively small species (males up to 45 mm SL) may be related to the species of the A. cacatuoides complex sensu stricto as well as to the A. trifasciata-group, but at the time has to be placed incertae sedis within the genus. A. arua sp. n. is characterised by a wedge-shaped spot on the abdominal flank beneath the lateral band, which sometimes, depending on mood, is modified to a line or band between the gill cover and the frontal base of the anal fin, or to three indistinct abdominal bands formed by three rows of half-moon-shaped spots. Males additionally exhibit a forked caudal fin and extended membranes to the first 5-7 dorsal fin lappets.

Ronald E. Watson and I-Shiung Chen: Freshwater gobies of the genus Stiphodon from japan and Taiwan (Teleostei: Gobiidae: Sicydiini), pp. 56-66

Three species of the freshwater goby genus Stiphodon (Sicydiini) recognized from Japan and Taiwan, are compared in text and tabular information. Stiphodon atropurpureus (Herre, 1927) is rediagnosed. Common in the Philippines, it is rare in Japan and Taiwan. It is distinguished in usually having 15 pectoral rays, 9 segmented second dorsal fin rays, and 30-33 lateral scales. Males are distinguished from other species in having a patch of white fatty tissue posterior to lower base of pectoral fin, first dorsal fin spines not elongate or filamentous, body and head grayish in preservation, in life with a bright metallic green stripe above the midline turning bright blue after death.  Females with a zigzag-like midlateral stripe and never with fatty tissue posterior to pectoral base. Stiphodon imperiorientis sp. n., is a rare species known from 10 specimens from Iriomote Island, Ryukyu Islands, and has 15 (15-16) pectoral rays, 9 segmented second dorsal fin rays, and 35-36 (34-36) lateral scales. It is distinguished in males always being without white fatty tissue posterior to lower base of pectoral fin, spines 4 and 5 elongate in first dorsal fin, in preservation body and head mostly tannish or brownish with dusky bars on trunk and caud-al peduncle, in life head bright blue, laterally blue between dusky bars. Female with midlateral stripe appearing mostly straight with blotches present ventral to second dorsal and on caudal peduncle. Stiphodon percnopterygionus sp. n., is a fairly common species in the islands of Iriomote and Ishigaki, Ryukyu Islands, Japan and eastern Taiwan, but very rare in Micronesia. It is distinguished by usually having 14 pectoral rays and 10 segmented second dorsal fin rays. Males are unusual in having two distinctive colour phases, young males mostly blue and older males mostly orange: colour phases are associated with size and not geographical distribution.

Gerald R. Allen and Samuel J. Renyaan: Three new species of Rainbowfishes (Melanotaeniidae) from Irian Jaya, Indonesia, pp. 67-78

¬ÝThree new melanotaeniid fishes are described from Irian Jaya. Melanotaenia batanta sp. n. is described from 12 specimens, 39.1-87.4 mm SL, collected at Batanta Island. It is most closely related to M. fredericki, but has a higher modal number of dorsal fin rays and fewer cheek scales. The remaining two species were collected in the Wapoga River system of northern Irian Jaya. Melanotaenia rubripinnis sp. n. is described from 51 specimens, 25.0-102.3 mm SL. It is most closely allied to M. vanheurni, but differs in colour, and generally has fewer soft dorsal rays and fewer cheek scales. Glossolepis leggetti, sp. n. is described from 79 specimens, 35.4-92.9 mm SL. It is most closely related to G. multisquamatus, but usually has a higher number of soft dorsal rays, fewer predorsal scales and a more slender body shape in adult males.

Rudie H. Kuiter: Pipefishes of the Syngnathid Genus Dunckerocampus (Sygnathiformes: Sygnathidae) with a Description of a New Species from the Indian Ocean, pp. 81-84

Dunckerocampus Whitley, 1933, is recognised as valid pipefish genus, rather than a sub-genus of Doryrhamphus Kaup, 1856, as treated by Dawson, 1985. A new species, D. boylei, with a distinctive broadly-banded pattern is described from the Indian Ocean, bringing the total number of species in the genus to six. Notes and underwater photographs of species occurring sympatric with D. boylei are provided.

Rudie H. Kuiter: A new Pygmy Angelfish (Teleostei: Perciformes: Pomacanthidae) from the Coral Sea, pp. 85-88

A new species of pomacanthid fish, genus Centropyge, is described from the Coral Sea. Centropyge woodheadi sp. n. lives in clear offshore conditions and is known from the Coral Sea to the Solomon Island and Fiji region. It is sympatric with the closely related C. heraldi Woods & Schultz, 1953, that is widespread in the West Pacific. The two species differ with regards to colour pattern, length of head and length of median fins.

Ivan Sazima and João Luiz Gasparini: A presumed hybrid of the hogfishes Bodianus pulchellus and Bodianus rufus in the western South Atlantic (Perciformes: Labridae), pp. 89-92

A  presumed hybrid between the hogfishes Bodianus pulchellus and B. rufus is described from the coast of Brazil. The putative Bodianus hybrid shows a bled of the colour pattern of the presumed parent species, a common trend among hybrids of several species of reef fishes.

Ronald E. Watson: Two new subgenera of Sicyopus, with a redescription of Sicyopus zosterophorum (Teleostei: Gobioidei: Sicydiinae), pp. 93-104

The sicydiine goby genus Sicyopus is divided into three subgenera based largely on dental characteristics found in both jaws. Juxtastiphodon, new subgenus, has conical teeth in both jaws crowded closely together, none recurved and without canines. Subgenus Sicyopus has widely spaced conical teeth in both jaw with most sharply recurved and without canines. Smilosicyopus, new subgenus, is with slightly recurved conical teeth anteriorly in both jaws, laterally needle-like teeth with none recurved, between anterior and lateral teeth, at least one (1-3) canine tooth, well developed imales. Sicyopus zosterophorum, tye species for Sicyopus, is redescribed. Juxtastiphodon, new subgenus, Sicyopus, and Smilosicyopus, new subgenus, most closely resemble Stiphodon in having pelvic disc fused to belly between fifth rays only; in all other sicydiine genera pelvic disc is fused between all five rays.

Jacques Géry: A new anostomid species, Leporinus bleheri n. sp., from the Rio Guaporé-Iténes basin, with comments on some related species (Teleostei: Ostariophys: Characiformes), pp. 105-112

A new anostomid species, Leporinus bleheri n. sp., from the Rio Guaporé-Iténez basin, with comments on some related species (Teleostei, Ostariophysi, Characiformes). Topotypical specimens of Leporinus pearsoni Flower, 1940 are redescribed. Leporinus bleheri n. sp., also from the upper Rio Mamoré basin and with a similar colour-pattern and ecology, is described and compared with it, as well as with two other species apparently belonging to the same taxonomic sub-unit.

Ronald E. Watson and Gerald R. Allen: New species of freshwater gobies from Irian Jaya, Indonesia (Teleostei: Gobiidae), pp. 113-118

¬ÝSicydiine gobies from Irian Jaya, Indonesia, and the region, are listed in the introduction. Three species ae described as new. Lentipes crittersius, new species, differs from congeners in having 19 pectoral rays, scales restricted to posterior half of body with some ctenoid scales on midline, and mid-lateral stripe slightly ventral to septum. Lentipes dimetron, new species, differs from congeners in having 15 pectoral rays, first dorsal spines erect with tips flexing posteriorly only slightly, cyclod scales restricted to posterior half of body, and pore D usually absent. Sicyopus (Smilosicyopus) mystax, new species, is distinguished from other in the genus with canine teeth in both jaws, in having 14 pectoral rays and no sexual dimorphism in jaw length.

Rudie H. Kuiter and Gerald R. Allen: Descriptions of three new wrasses (Teleostei: Perciformes: Labridae: Paracheilinus) from Indonesia and North-western Australia with evidence of possible hybridisation, pp. 119-132

Three new species of the labrid genus Paracheilinus are described from Indonesia and offshore reefs of north-western Australia. Paracheilinus cyaneus, new species, is described from two specimens, 48.7-52.2 mm SL, collected at the beggai Islands, Sulawesi. It is distinguished from other members of the genus by a consistently higher number of elongate dorsal filaments and colour pattern, particularly that of displaying males, which have iridescent blue over most of the head, back, and dorsal fin, in addition to bright red dorsal filaments. Paracheilinus flavianalis, new species, is described from 20 specimens, 20.2-53.0 mm SL, collected at Bali Indonesia and Scott-Seringapatam reefs, Western Australia. Males of P. flavianalis have a yellow anal fin, whereas in the closely related P. maccoskeri this fin is deep red on the outer two-thirds and yellow basally, the  two colours being separated by a violet band. Males of P. flavianalis also different in having a distinctive dark red mark at the middle of the outer part of the dorsal fin, which encompasses the first three soft dorsal rays (at least one of these forms a long filament). Paracheilinus togeanensis, new species, is described from a single specimen, 47.8 mm SL, collected at the Togean Islands, northern Sulawesi. It is distinguished by colour pattern, a lack of dorsal fin filaments, a lunate caudal fin, and rounded posterior profile of the dorsal fin.

Volume 3, Issue 4 - December 1999

Gerald R. Allen and Rudie H. Kuiter: Descriptions of two New Wrasses of the Genus Cirrhilabrus (Labridae) from Indonesia, pp. 133-140

Two new species of labrid fishes are described from Indonesian seas. Cirrhilabrus aurantidorsalis, new species, is described from a single male specimen, 84.1 mm SL, collected off Togean Islands in tomini Bay, Indonesia. It is closely allied to C. solorensis, but differs on the basis of male colour pattern, particularly the bright orange area on the upper back and dark violet ”crown’ on the forehead. Cirrhilabru tonozukai, new species, is described from three specimens, 55.8-58.1 mm SL, collected at the Baggai Islands off central eastern Sulawesi, Indonesia. It is closely related to C. filamentosus, but males have a shorter forsal fin filament and differ in colour pattern, as well as attaining a smaller size. These two species differ from other members of the genus (hence their placement in the subgenus Cirrhilabrichthys Klausewitz) by a combination of characters that include a prolonged, filamentous extension of the posterior dorsal spines in males, a rounded caudal fin, and a single row of cheek scales.

Gerald R. Allen and Aaron P. Jenkins: A Review of the Australian Freshwater Gudgeons, Genus Mogurnda (Eleotridae) with Descriptions of Three New Species, pp. 141-156

The six Australian members of the freshwater fish genus Mogurnda are reviewed, including description of three new taxa. Mogurnda adspersa (Castelnau) ranges southward in Pacific coast drainages from Cape York Peninsula to the Clarence River of northern New South Wales. It so also widespread in the Murray-Darling system of inland New South Wales and Queensland. Mogurnda mogurnda (Richardson) is distributed across northern Australia from the Kimberley region to Cape York Peninsula. Mogurnda larapintae (Zietz) is confined to the Finke River system of central Australia. It was formerly confused with M. mogurnda, but is clearly separable on the basis of its smaller scales. Mogurnda oligolepis new species is described from 75 specimens, 15.8-62.7 mm SL, collected in the Kimberley region of northern Western Australia. It is similar to M. mogurnda, but differs in having larger body scales, modally fewer dorsal and anal fin rays, and a smaller maximum size. Mogurnda clivicola new species is described from 61 specimens, 21.3-69.8 mm SL collected in the northern flinders Ranges of South Australia. It is distinguished from other central desert Mogurnda (i.e. M. larapintae and M. thermophila) by its colour pattern and modal counts for vertebrae, lateral scales, predorsal scales, circumpeduncular scaler, and pectoral rays. Mogurnda thermophila, new species is described from 25 specimens, 12.6-98.6 mm SL, collected from the complex of thermal springs at Dalhousie, South Australia. It is similar in general appearance to M. larapitae, but has larger scales.

Gerald R. Allen and Bradley J. Pusey: Hephaestus tulliensis De Vis,a valid Species of Grunter (Terapontidae) from Fresh Waters of North-eastern Queensland, Australia, pp. 157-162

Hephestus tulliensis De vis was formerly considered a junior synonym of H. fuliginosus Macleay, but evidence is provided for its recognition as a valid species. The two species differ in a variety of characters including number of lateral body scales, preopercular and opercular serration/spination, body depth, eye width, interorbital with, maxillary length, caudal peduncle depth, and length of fin spines/soft rays of the dorsal, anal, pectoral, ad pelic fins, a redesription is provided for H. tulliensis and it is compared with h. fuligiosus, the two species having sympatric distributions in certain freshwater habitats of north-eastern Queensland, Australia.

Gerald R. Allen and Samuel J. Renyaan: Pseudomugil ivantsoffi (Pseudomugilidae), a new species of blue-eye from the Timika region, Irian Jaya, pp. 163-168

Pseudomugil ivantsoffi, a new species of blue-eye, is described on the basis of 60 specimens, 17.9-30.8 mm SL, collected from the Timika vicinity of southern Irian Jaya. The new species was formerly confused with P. reticulates, which occurs in the vicinity of Lake Ayamaru on the Vogelkop Peninsula of Irian Jaya. The differences between these two species are contrasted and illustrations of each are provided.

Steven Grant: A replacement name (Nomen novum) and neotype designation for Hara malabarica Day, 1865, with notes on related species (Siluriformes), pp. 169-174

¬ÝA neotype is designated and a replacement name proposed for Hara malabarica Day, 1865. The species is also moved to the family Bagridae, and to the genus Mystus Scropoli, 1777. The identity of Mystus malabaricus (Jerdon, 1849), Mystus montanus (Jerdon, 1849) is discussed in view of misidentifications made previously. The generic placement and validity of Mystus maydelli R??ssel, 1964, ad Mystus var. dibrugarensis Chaudhuri, 1913, is also discussed.

Allen, G. R. and S. J. Renyaan: Three new species of rainbowfishes (Melanotaeniidae) from the Triton Lakes, Irian Jaya, New Guinea, pp. 13-24.

Three new melanotaeniid fishes are described from the Triton Lakes area of western Irian Jaya, Indonesia. They are closely related to one another and apparently evolved from an ancestor of the wide-ranging Melanotaenia goldiei. Melanotaenia kamaka n. sp. is described from 29 specimens, 38.5-60.5 mm SL, collected at Lake Kamakawaiar, and M. lakamora n. sp. is described on the basis of 75 specimens, 25.5-54.9 mm SL, from nearby Lake Lakamora and Lake Aiwaso. They differ primarily in colour pattern, but also in modal number of anal fin rays and the length of the poster rays of males (those of M. lakamora are more elongate). Melanotaenia pierucciae, the third new species, is described from 13 specimen, 28.9-58.7 mm SL, collected from a small creek near Lake Kamakawaiar. It is similar to M. kamaka and M. lakamora, but differs in colour pattern and proportions. Males are more slender and the species also has a more slender caudal peduncle, and shorter dorsal rays in the second dorsal fin. It further differs from M. kamaka in having a shorter caudal peduncle and shorter anal rays.

Andreone, F.: Another new green treefrog, Boophis anjanaharibeensis n. sp. (Ranidae: Rhacophorinae), from northeastern Madagascar, pp. 25-32.

In the course of a series of herpetological surveys in Madagascar a new arboreal frog belongin to the ”green Boophisi group’ (family raidae, subfamily Rhacophorinae) has been discovered. Boophis anjanaharibeensis n. sp. was found in the mid-altitude rainforest of the Anjanaharibe-Sud Special Reserve, in northeastern Madagascar. It is similar ins ome characters to B. luteusi and to B. elenae, from which it differs in the greater development of the head and eyes and in the coloration, dorsally dark green with scattered light spots. The eyes are not red, as in B. l. luteus, but golden with a narrow outer brownish area. The belly is whitish with bluish shadings, as well as digital expansions.

¬ÝElecantinus figaro n. sp., a cleaner goby of the horsti complex, is described from the coast of Brazil. The new species differs from its congeners of the horsti complex by the combination of the following characters: enlarged caninens lacking in females, pale dorso-lateral stripe (bright yellow in life) reaching the lateral septum, and pale median spot (bright yellow in life) on snout. This species represents the southern most record for a cleaner goby in the western South Atlantic.

¬ÝThe ontogenetic development, reproduction, feeding habits and habitats and habitat of the stingrays Paratrygon aiereba and Potamotrygon orbingyii from the Venezuelan Ilanos (Apure river basin) were studied. According to the ontogenetic development, four stages were considered. Fetuses, immatures, sexually maturing and mature individuals. The variation of 12 measurements and their development in relation to disk width are described. P. aiereba attained greater size (780 mm DW) and weight (25 kg) than P. orbignyi (325 mm DW) and weight (2 kg). In P. aiereba males, sexual maturity is apparently reached at a size larger than 410 mm DW, whereas in P. orbingyi sexual maturity is attained at 230 DW. Females show signs of sexual maturation at 370 and 185 mm DW in P. aiereba and P. orbignyi respectively. Pregnancy and littering in both species goes on all year. Births seem to be more frequent during the rainy season. According to our data, the litter size varies between one and two young in each reproductive cycle in both species. P. aieereba is a piscivore even though shrimps are important items in tis diet. P. orbignyi is essentially an insect feeder. P. aiereba has been observed obly in the main channel of the Ca?±o Guaritico (clear water) whereas P. orbignyi is usually found in a wide range of habitats and water types.

W. Ivantsoff, Aarn, Margaret A. Shepherd and G. R. Allen: Pseudomugil reticulatus (Pisces: Pseudomugilidae) a review of the species originally described from a single specimen, from Vogelkop Peninsula, Irian Jaya with further evaluation of the systematics of Atherinoidea, pp. 53-64

¬ÝPseudomugil reticulates, hitherto only known from a single specimen from Vogelkop Peninsula, Irian Jaya is redescribed on the basis of selected specimens collecte din the environs of Timika and Tembagapura, (approx. 4¬? 23??S 136¬?53??E) Irian Jaya. Examination of a large number of specimens allows for a much more accurate description of meristics, morphometrics, coloration, and sexual dimorphism. Osteological study of P. reticulates provides a clear cut diagnosis of the species. Although the present study does not contradict the hypothesized systematic position of Pseudomugilidae, it suggests that Telmatherinidae, Pseudomugilidae and Melanotaeniiae may form a transformation series. The latest definition of the family Pseudomugilidae and the genus Pseudomugil are given.

J. Géry & U. Römer: Tucanoichthys tucano gen. n. sp. n., a new miniature characid fish (Teleostei, Characiformes, Characidae) from the Rio Uaupés basin in Brazil, pp. 65-72

A new dwarf genus and species, Tucanoichthys tucano, less than 17 mm in maximal standard length, is described. It comes from a brook tributary of the Rio Uaupés, upper Rio Negro basin, in Brazil. Its affinities are discussed. It belongs to the Characidae in the broad sense, but could not as yet be attached to a particular subfamily. Its ecology and behaviour are also described, following observations in the field as well as in the aquarium.

Romer: Uwe: Apistogramma mendezi nov. sp. (Teleostei: Perciformes: Cichlidae): description of a new dwarf cichlid from the Rio Negro system, Amazonas State, Brazil, pp. 1-12.

¬ÝApistogramma menezi n. sp. (Fig. 1) is described on the basis of 18 specimens from a little river near Barcelos do Rio negro, Dept. Amazonas, Brazil (near 63.04??W / 0.01??S). For biometric data see Table I. Separated from all other Apistogramma species except A. paucisquamis, A. elizabethae and A. uaupesi by the prolongation of spies D3 and V3 in lyrate caudal fin. In contrast to A. paucisquamis, A. mendezi shows complete squamation of caudal peduncle, lacks the positive growth-allometry of lower jaw, 3(-4) narrow ventral bars of vent (versus 1 wide in a. paucisquamis) and always missing bars in caudal fin. Distinguished from A. uaupesi by completely different colouration and unprolonged membranes of dorsal fin. A. elizabethae also shows a completely different dorsal fin shape. A. mendezi was foud syntoptically with A. gephyra and A. gibbiceps in a fast following water with gravel-like bottom. Females in breeding colours have been caught.

Sands, D.D.: Crypsis in Corydoras (Pisces: Siluriformes: Callichthyidae), pp. 13-20.

Cryptic pattern sharing amongst a number of sympatric species of Corydoras has yet to be fully understood. The possible development of pigment patterns alongside crypsis behaviour if discussed. Laboratory research details the behaviour of Corydoras adolfoi Burgess, 1982, and Corydoras imitator Nijssen & Isbrücker, 1983, sympatric in a tributary of the Upper Rio Negro, Brazil. Data, based on observations of combined species groups has shown that both freeze in the presence of a predator model or a live predator. Predator-prey reactions are recorded for both species when they are together and grouped with allopatric Corydoras species.

Kaspiris, P., A. Argyriou and A. Vertsiotis: Food of Hygophum benoiti (Pisces: Myctophidae) in Korinthiakos Gulf (Greece), pp. 21-24.

The present study examines the diet of Hygophum benoiti (Cocco, 1838) from specimens collected in May and July 1990 in the Korinthiakos Gulf. This mesopelagic fish migrates during the night towards the surface where zooplankton is more abundant and from which this species is feeding.

Banister, K. E.: Glossogobius ankaranensis, a new species of blind cave goby from Madagascar (Pisces: Gobioidei: Gobiidae). pp. 25-28.

A new species of cave-adapted goby, glossogobius ankaranensis, is described from a subterranean river in the Ankarana massif in northern Madagascar. The only other hypogean fishes from the island are two species in the family Eleotrididae from the south west of the country. It is most probably related to the widespread epigean and euryhaline Glossogobius giuris (Hamilton, 1822).

Klossa-Kilia, E. and I.C. Ondrias: Age, growth and length-weight relationship of brown trout Salmo trutta L. in the upper stream of Acheloos River, Greece, pp. 29-36.

The age, growth, length-weight relationship and condition factor (k) of brown trout, Salmo trutta L. was studied in a small tributary of the Acheloos river. Totally 309 specimens were collected. The age group 1+ and 2+ formed the greatest part of the population. The annual growth was estimated with the back-calculation method based on the relationship between scale radius and body length in 101 individuals. The length-weight relationship can be described by the following equations: W = 0.0000266 L2.865 and W = 0.0000322 L2.825 for males and females respectively. The average codition factor (k) ranged from 1.16-1.25 and 1.10-1.21 for males and females respectively.

Géry, J.: Description of new or poorly known Alestinae (Telostei: Characiformes: Alestidae) from Africa, with a note on the generic concept of the Alestinae, pp. 37-63.

¬ÝDescription of new or poorly known Alestinae (Teleostei: characiformes: Alestidae) from Equatorial Africa, with a note on the generic concept in the Alestinae. The study is in two parts. In the first part, the difficulties encountered in the generic attributions of certain species are pointed out, and the generic concept in Alestinae is discussed. A key to the so-called dwarf African Tetras (tribe Petersiini) is given. Their number is reduced, compared to that proposed by Poll (1967), but the monophyly of several of these genera cannot, at the moment, be demonstrated. In the second part, 3 new species are described: Brycinus fwaensis n. sp., from Lake Gwa, Micralestes ambiguous n. sp. and Phenacogrammus bleheri n. sp., from northern Za?Øre (Oubangui basin, Equateur Province); what is probably a new form is described but not named: Brycinus sp. Agg. Chaperi (Sauvage, 1882); 5 poorly-known species are discussed and, in some instances, redescribed: Brycinus abeli (Fowler, 1936), Phenacogrammus ansorgii (Boulenger, 1910), Pheacogrammus gabonensis (Poll, 1967) and Phenacogrammus aurantiacus (Pellegrin, 1930). Phenacogrammus ansorgii is newly recorded from the interior part of Equatorial Africa as is Brycinus abeli from northern Za?Øre. In the appendix, and index of the scientific names cited in the seminal revision of the Petersiini by Poll (1967) is given, in the hope that it will permit easier access to the references of the present study and others.
