More Info

Body depth 3.0-3.7 in SL; pelvic fraenum and branched dorsal-fin rays present; ctenoid body scales to level of base of pectoral fin; predorsal, cheek, opercle, prepelvic area and base of pectoral fin without scales; no vertical rows of papillae on cheek.

Size

Maximum total length, about 4 cm.

Remarks

The specific name i sderived from the Latin nucha (= neck) + Latin adjective fasciatus (= banded) and is an adjective, hence the name is nuchifasciata, not nuchifaciatus (Hoese 2017)

Similar Species

Although very similar to the Halfbarred Reefgoby, Priolepis semidoliata, the Threadfin Reefgoby differs from all other species in the genus Priolepis in having both a pelvic fraenum (a flap of skin connecting the pelvic-fin bases) and branched dorsal-fin rays.

Etymology

The specific name nuchifasciata is from the Latin nucha (= nape, neck) and fasciatus (= banded), presumably in reference to the vertical bands on the head and nape.
