The new species can be well distinguished from other congeneric species by following combination of features: dorsal fin rays 3+8, pectoral fin rays 13+11 (total 24); lateral-line scales 78–80, predorsal scales 31–32; head shape somewhat pointed; small pelvic fin which not extending to rear vertical of dorsal fin; position of anus with larger distance of pelvic rear tip to anus about three times to that of anus to anal fin origin; and specific coloration: predorsal region in having many very small, irregularly light brown marks and pectoral fin unmarked (Ref. 80631).
