Abstract
A new species of damselfish, Pomacentrus bellipictus, is described from 13 specimens, 37.7-67.9 mm SL,
collected at the Kokas area of the Fakfak Peninsula, a portion of the Bird's Head Peninsula of western New
Guinea (West Papua Province, Indonesia). It is distinguished from most similar species in the western Pacific
Ocean by having 14 instead of 13 dorsal-fin spines. It also possesses a unique facial coloration consisting of
highly contrasted blue areas around the mouth and onto the isthmus, below the eye, and along the margin of the
preopercle. The only other species of Pomacentrus from the region with 14 dorsal spines that are also drab-brown
when alive, P. fakfakensis and P. opisthostigma, are clearly distinguished on the basis of adult and juvenile color
patterns and also show different habitat preferences. In addition, P. opisthostigma is distinguished from the other
two species by fewer lateral-line scales (usually 15-17 vs. usual 18-19) and more gill rakers on the first arch
(26-29 vs. 18-21). The three species co-occur in the Kokas area, but occupy different habitats: Pomacentrus
bellipictus inhabits rocky, wave-washed shorelines in about 1-2 m depth, while the other two species occur in
deeper water. The new species is apparently endemic to the small area around the Fakfak Peninsula, where several
other microendemic reef fish species have been described.
