Dorsal fins almost of similar size, not falcate; interdorsal space 18.2 – 19.4 % TL. First dorsal fin slightly larger, length 13.4 – 15.1 % TL, height 5.8 – 8.3 % TL, subtriangular (with a narrowly rounded apex in juveniles), posterior margins nearly straight to shallowly concave and its free rear tip reaching just anterior to pelvic-fin origin. Second dorsal fin almost as high as first, subtriangular, length 11.2 – 12.1 % TL, height 5.2 – 7.1 % TL, 82 – 92 % of first dorsal-fin height. Pectoral fin moderately long, 12.5 – 15.5 % TL and not falcate, anterior margins weakly convex; pelvic fin moderately long 9.8 – 11.5 % TL; anal-fin height 3.8 – 6.0 % TL. No dermal ridge between dorsal fins, and no keels on caudal peduncle. Upper anterior teeth subtriangular (almost cordiform), evenly serrated. Lower anterior teeth long, narrow, erect, with entirely smooth cutting edge; tooth row counts 40 – 44 / 40 – 44. Fins without any prominent markings in adults.
