Etymology: Priolepis: Greek, prio = to saw + Greek,lepis = scale (Ref. 45335); nuchifasciata: Name from Latin nucha meaning nape and fascia meaning band, referring to the banding pattern on the head; noun in apposition (Ref. 9018). More on author: Günther.
Environment: milieu / climate zone / depth range / distribution range
Marine; brackish; reef-associated; non-migratory; depth range 5 - 30 m (Ref. 90102). Subtropical
Western Pacific: confined in the area, Australia, New Guinea, Indonesia, Philippines to Hong Kong, westward to the Gulf of Thailand; probably in Vietnam; questionable in Oman (unreported specimens).

Maturity: Lm ?  range ? - ? cm
Max length : 4.0 cm TL male/unsexed; (Ref. 9002)
(total): 6 - 7;
soft rays: 6 - 8. Distinguished from its congeners in having a pelvic fraenum and branched dorsal-fin rays (Ref. 9018); characterized by reddish to mauve with dark scale margins forming network on side of body; head and upper back below dorsal fin with series of dark-edged pale grey to whitish bars; pair of bars found anterior to pectoral fin forming inverted "Y"; sometimes with yellow head; longitudinal scale series 23-26; ctenoid body scales to level of base of pectoral fin; predorsal, cheek, opercle, prepelvic area and base of pectoral fin without scales; absence of vertical rows of papillae on cheek; depth of body 3.0-3.7 in SL (Ref. 90102).
Found in rocky estuary reefs, in small caves, usually in pairs (Ref. 9002). Cryptic (Ref. 90102).
