Etymology: Pteragogus: Greek, pteron = wing, fin + Greek, ago = to drive (Ref. 45335).
Environment / Climate / Range
Marine; reef-associated; depth range 2 - 12 m (Ref. 90102). Tropical; 19°N - 12°S
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 9.0 cm TL male/unsexed; (Ref. 48636)
(total): 9-10. This species differs from P. cryptus by having a concave rather than straight dorsal head profile, a higher modal gill raker count, and a series of five well-defined dark brown spots on the mid lateral line (these spots may be present on some P. cryptus, but are never well-defined). Best identified by the thin white barring on dorsal fin and upper sides (Ref. 48636). SL to 57 mm.
Western Central Pacific: Indonesia, Philippines, Solomon Islands, New Guinea and Palau.
Found in sheltered inner reefs amongst broken coral and rubble. Usually seen in less than 10 m depth, staying well hidden in reefs, but sometimes swimming amongst the long-spined Diadema urchins or in thick algae coverage (Ref. 48636).
