Dorsale stekels (totaal) : 10; Dorsale zachte stralen (totaal) : 9; Anale stekels: 3; Anale zachte stralen: 7. This species is distinguished by the following characters: body moderately elongate, its depth 3.2-3.6 in SL; head length (HL) about equal to its body depth, 1.0-1.1 in HL; eye diameter a little less than snout length, 1.2 in snout; the lower margin of eye well above a line from tip of snout to upper pectoral fin base; suborbital is moderately deep, the lower edge emarginate, least depth 1.0-1.5 in eye diameter; imaginary line extended upward from posterior edge of suborbital reaching dorsal profile about 2 scale rows before origin of dorsal fin; pectoral fins are moderately long, reaching to about level of the vent; pelvic fins are very long, reaching to between level of vent and origin of the anal fin; upper lobe of caudal fin rounded and slightly longer than lower, but not produced; scale rows below lateral line more or less horizontal; maxillary reaching to between level of posterior nostril and anterior margin of the eye. Colouration: body pinkish-mauve; snout with two narrow yellow bands, the uppermost from anterior margin of eye through nostrils, the lower band from just in front of lower margin of eye to anterior edge of suborbital; upper lip is narrowly edged with yellow while the lower lip and chin beneath lip are yellow, this colour extending as narrow band posteriorly to lower margin of opercle (Ref. 93175).
