Diagnosis: Dorsal fin IX, 14- 15; anal fin III,8-9; pectoral fin rays 17- 18; lateral--line scales 45 -50; lateral scale series 73-80; gill-rakers 8- 10 + 14- 17; 5 or 6 rudiments on each limb. Body depth distinctly less than head length, contained 2.8-3.0 times in SL (for fish 11 - 15 cm. SL); head length 2.5 -2.6 times in SL; pectoral fins 1.4- 1.7 times in head length; pelvic fins reach anus, 1.6 - 1.9 times in head length. Caudal fm rounded; dorsal fin membranes distinctly indented between the spines. Eye diameter greater than interorbital width, 4.6-5.5 times in head length. Interorbital area flat; preopercle rounded, finely serrate, the lower edge fleshy; subopercle and interopercle smooth; upper edge of operculum convex. Maxilla scaly, reaching well past eye. Lateral body scales ctenoid, without auxiliary scales.

Colour: Dark brownish, with 3 or 4 indistinct dark bars on body (extending onto dorsal fin) and 2 more on caudal peduncle; belly reddish; sides of head with close-set reddish spots forming a reticulated pattern of dark lines; pelvic and anal fins dusky, with small pale (silvery?) spots; tips of interspinous dorsal fin membranes black.

Maximum total length: 30 cm.
