Diagnosis

This small species is distinguished by the following characters: snout relatively long and bluntly pointed; upper anterior teeth are oblique and blade-like, coarsely serrated, lateral margin deeply notched and with several large and serrated basal cusplets; lower anterior teeth are narrower, slightly oblique, lateral margins notched and without large basal serrae, finely serrated; total tooth row counts 26-28/24-30 rows or 51-55; interdorsal space often with a moderate to strong ridge, 19.4-22.0% TL; first dorsal fin is relatively low, not falcate, origin over middle of pectoral-fin inner margin, length 14.1-15.6% TL, 1.4-2.0 times height, inner margin 2.0-2.7 in base; second dorsal fin is much smaller, broadly triangular, height 29-37% of first dorsal fin height, origin slightly posterior of anal-fin origin; anal fin is slightly falcate, height 0.9-1.3 times second dorsal-fin height, base 0.9-1.2 times second dorsal-fin base; body colour pale brownish dorsally, whitish ventrally; second dorsal fin with a black blotch on upper third of fin, not extending onto upper surface of body and very well defined from whitish region below; other fins are mostly plain; total vertebral counts 113-129; monospondylous precaudal counts 37-44; diplospondylous precaudal counts 17-19; diplospondylous caudal counts 58-72; precaudal counts 55-63 (Ref. 89954).
