Valdesalici,
Stefano and Rudolf H. Wildekamp: A new species of the genus Nothobranchius (Cyprinodontiformes:
Nothobranchiidae) from the Luapula River basin, Zambia, pp. 89-96
Specimens
of three different populations of a Nothobranchius species, collected from ephemeral pools
in the Luapula/Bangweulu catchment in Zambia, are considered to be one species
on the basis of the coloration of males. The new species has been compared with
the Nothobranchius species now known to exist in the same river system. It differs
in some morphological features from the other species of Nothobranchius in the same river system and has
a distinct colour pattern. Information on its present known distribution is
given, as well as on its relationship to the other Nothobranchius species in Zambia and in the
adjacent region of the Democratic Republic of Congo.

Cristina, Bolando, Roberta Martini, Krajewsk, João Paulo and Ivan Sazima: The
Noronha wrasse: a jack-of-all-trades follower, pp. 97-108
Following
association between reef fishes involves opportunistic predators following one
or more foraging nuclear species (mainly bottom-diggers). The followers benefit
from food uncovered or flushed out when reef fishes disturb the bottom. At the
Fernando de Noronha Archipelago, south-west Atlantic, we recorded the plankton
eater, benthic invertebrate picker, and cleaner wrasse Thalassoma
noronhanum, commonly
known as the Noronha wrasse, acting as a very flexible feeder – a kind of
jack-of-all-trades – while following reef fishes. The Noronha wrasse
associated with 15 reef fish species, feeding on drifting particles made
available as the latter foraged on the bottom. The wrasse displayed four types
of feeding behaviour while following foraging reef fishes: 1) eating particles
stirred up; 2) eating particles expelled by the foraging fish; 3) eating faecal
particles; 4) cleaning fish. The wrasse was commonly recorded following the
parrotfishes Sparisoma frondosum, S. axillare, S. amplum, and the grunt Haemulon parra. The variable feeding behaviour
here recorded for T. noronhanum while following reef fishes seems rare among follower fish
species. Nevertheless, some wrasse species have very opportunistic foraging
habits as well, which render them likely candidates to display flexible feeding
behaviour.

Richard, Iwata, Akihisa and
Toshikazu Kozawa: Vanderhorstia nannai, a new species of burrow-associated
goby from Palau and the Philippines (Pisces: Gobiidae), pp. 109-114
A new
species of the shrimp-associated gobiid genus Vanderhorstia, V. nannai, is described from four specimens
collected in Palau, and from 15 aquarium specimens reputedly from the
Philippines. The presence of this species in the latter area is supported by an
image of the live fish photographed in situ in the Philippines available on the
internet. It is distinguished from its congeners by the elongate 5th and 9th
branched caudal fin rays; 16-18 pectoral fin rays; 41-45 lateral scale rows; no
scales in the predorsal midline; coloration pale off-white background with six
prominent yellow orange spots haloed with blue on the midlateral surface of the
body and smaller yellow-orange spots and blue spots and streaks on the head; a
single papilla on row cp÷; an uninterrupted row b on the cheek; and a total of two to four
papillae in a transverse row across the chin (row f).
