mouth width 3.4-4.3 times the length of upper labial furrow; interorbital width 1.4-1.5 times the horizontal preorbital length; fifth gill slit height 1.9-2.1% TL; strongly bifurcated anterior nasal flap; first dorsal fin upright, upper posterior margin almost vertical, greatest concavity closer to free rear tip than fin apex; posterior margin of second dorsal fin deeply concave; second dorsal-fin spine with a broad base; pectoral fin of adult weakly falcate, anterior margin long, 14.6-16.4% TL; both dorsal and ventral surfaces are pale; dorsal fins pale with obvious dark
tips; first dorsal-fin spine and base of soft portion of dorsal fin both pale; caudal fin with broad white posterior margin; prominent dark, diagonal subterminal streak parallel to the upper posterior margin; flank denticles strongly tricuspid; monospondylous centra 47-49, precaudal
centra 94-97, total centra 123-127 (Ref. 58440).
