This species is distinguished by the following set of characters: moderately long snout; similarly-sized dorsal fins; when mouth is closed, the lips mostly concealing teeth, except near symphysis; upper anterior teeth broadly triangular and serrated; lower anterior teeth long, narrow, erect, with non-hastate cusps which are either smooth or finely serrated; tooth row counts 33-40/34-40; interdorsal space 16.2-20.4% TL; pectoral-fin anterior margins weakly convex, its length 12.4-14.4% TL; pelvic fin anterior margins 7.4-9.3% TL and 48-53% of pectoral anterior margin; first dorsal fin is relatively small, raked, sub-triangular, with nearly straight to shallowly concave posterior margin, its free rear tip just anterior to pelvic-fin origins, length 14.9-17.1% TL, height 5.6-8.1% TL; second dorsal fin large, sub-triangular, almost as high as first dorsal fin, length 11.8-14.3% TL, height 4.8-7.3% TL and 83-93% of first dorsal-fin height; anal-fin height 3.8-5.6% TL and 70-85% of second dorsal-fin height, base 78-98% of second dorsal-fin base; 174-181 total vertebral centra, precaudal 98-100, monospondylous precaudal centra 50-51 and 28-29% of total centra, diplospondylous precaudal centra 48-49 and 27-28% of total centra, diplospondylous caudal counts 75-81 and 43-45% of total counts; demarcation of light and dark colour surfaces (waterline) on head strong, extending from lateral angle of snout to upper margin of eye, dark surface not visible in ventral view of head; fins lack distinct black or white tips or markings (Ref. 84282).
