A new species of goby, Priolepis billbrooksi
n. sp., is described from mud-bottom habitat in 30
m depth at Milne Bay Province, Papua New Guinea, on
the basis of 5 specimens, 13.3-22.7 mm SL. It
belongs to a group of Priolepis that share
a well-developed pattern of transverse cheek papillae,
but differs from other members of the group by a combination
of diagnostic features that include dorsal-fin elements
VI + I, 9-10 (usually 9), a second dorsal-fin
spine forming an elongate filament extending to between
the base of the fourth and the last segmented dorsal-fin
ray when adpressed, anal-fin rays I, 8-9 (usually
9), pectoral-fin rays 18, a relatively broad interorbital
(75-91% pupil diameter), 10-12 papillae
in the posterior transverse interorbital row, the
upper portion of the opercle with about 10-12
scales arranged in 3 or 4 transverse rows, no pelvic
frenum, and the color when fresh generally yellow
with numerous pepper-like melanophores.
