Épines dorsales (Total) : 18 - 19; Rayons mous dorsaux (Total) : 10 - 11; Épines anales: 2; Rayons mous anaux: 20 - 21. This species is distinguished by the following characters: D IV + XIV-XV + 10-11 (IV+XV+11); A II, 20-21 (21), spine length half of the rays; pectoral rays 16, dorsalmost 2-3 and ventral most 7 simple, remainder branched once; pelvic rays bound together by membrane for less than one-fourth of length of shorter ray; lateral line pored scales 21-24 (22), terminates between 2nd and 3rd dorsal fins; notched scales and 14-19 (16); total lateral scales 32-35 (34); dentary pores 5-6 + 1 + 5-6; orbital and nasal cirri palmate and about as large as pupil diameter; dorsal fin also with cirri at tips of spines; head 2.9-3.6 (3.3) in SL, eye 3.0-3.9 (3.3), maxilla 2.3-3.0 (2.6) and snout 3.3-4.9 (3.8) in head length (Ref. 88983).
Adults inhabit coral or rock, often under ledges, on clear lagoon and seaward reefs (Ref. 13227). Eggs are hemispherical and covered with numerous sticky threads that anchor them in the algae on the nesting sites (Ref. 240). Larvae are planktonic which occur primarily in shallow, nearshore waters (Ref. 94114).
