Diagnostic Features: Prenarial snout 4 to 5% of total length; upper labial furrows short, 0.7 to 1.1% of total length; total count of enlarged hyomandibular pores on both sides of head just behind mouth angle usually over 16 (7 to 11 per side); teeth not serrate; total tooth rows usually 24 to 25/21 to 23. First dorsal origin over pectoral free rear tips; second dorsal origin ranges from above last fourth to sixth of anal base; pectoral anterior margin shorter than first dorsal length from origin to free rear tip; adpressed pectoral apex reaching first third of first dorsal base or ending in front of it. Posterior monospondylous precaudal centra hardly enlarged; precaudal centra less numerous than caudals, precaudals 73 to 80, total counts 135 to 149. Size small, males maturing over 40 cm total length. Colour brownish-grey above, white below, fins light-edged but not conspicuously marked.. [517]
