This species is distinguished by the following characters: body depth less than head length, 2.5-3.0 times in SL; large head length 2.1-2.4 times in SL; rounded preopercle with 3-6 enlarged serrae at the angle; upper edge of operculum slightly convex; midside of lower jaw with 2 rows of teeth; gill rakers of first gill arch 8 + 14-16 = 22-24; scaly maxilla, reaching about vertical at rear edge of eye; pectoral and pelvic fin length are equal, 1.7-2.3 times in head length; ctenoid lateral body scales, few auxiliary scales in adults. Colour of head, body and median fins are pale grey; 5 broad dark brown bars, first 2 extending into the spinous part of dorsal fin, 3rd and 4th bars extending into the soft dorsal and anal fins, 5th dark bar at the base of the caudal fin; edges of dorsal parts of body bars with small black spots; nape with dark brown saddle blotch, small black spots mainly along edge of the blotch; cheeks, snout, interorbital area, jaws and chest mostly dark brown, with 2-3 white bands radiating from the eye; irregular black bar on the middle of the caudal fin; yellow maxillary groove; small juveniles (6 cm SL) white, with black bars on body as described for adults, the fins pale yellow with small black spots (Ref. 39231, 89707).
This species is usually found on offshore coral and rocky reefs. A popular and commercially important species in Hong Kong, but not in Singapore. Caught with hand lines and sold fresh (Ref. 39231).
