Rayed dorsal fin inserted above ¾ of the length of pectoral fin, inner margin of dorsal spine serrated ¾ from the base with 12- 24 teeth, pectoral fin with 22- 30 antrorse teeth along inner edge of its spine, pelvic fin not reaching anal fin; Dorsal fin and its spine, pectoral fin and its spine shorter than its relative species. The fish is described and compared with its related species.
