Description
Dorsal spines (total): 6-7; Dorsal soft rays (total): 10-11; Anal spines: 1; Anal soft rays: 10-11; Pectoral fin rays: 17; Longitudinal scale series: 77-92; Greatest depth of body: 5.4-6.0 in SL. Body elongate, compressed. Head slightly compressed; Jaws subequal, not reaching to a vertical through posterior margin of eye; Gill opening reaching anteriorly around a vertical through posterior margin of preopercle. Pelvic fins united medially; Frenum present. Scales cycloid or weak ctenoid; Head, breast and pectoral-fin base naked. Sensory canals and pores present on head; Distinct transverse sensory-papillae rows on cheek; A pair of short longitudinal sensory papillae rows just behind chin. Rounded caudal fin, longer than head length. Max. length: 12.0 cm SL. Depth range: 0 - 18 m.
Color
Body brownish-green, becoming whitish ventrally; Six-seven diffuse brownish bars on side; Head, back and dorsal fins with pale-edged pink to red spots and smaller white spots; First dorsal fin with blue-edged orange to brown spots.
