Dorsal fin IX, 13-15 (rarely 15); Anal fin 13-15 (rarely 13 or 15); Pectoral fin 11 + 3; Lateral line 55–57 pored scales; Scales below lateral line ~16-17; Vertebrae 11 + 20 (rarely 20) = 30-31 (rarely 31); Gill rakers 0 + 6-7 (rarely 7) and sometimes 1 or 2 rudimentary rakers laterally on lower limb of first gill arch.
Pectoral-fin tip reaching base of tenth to fourteenth anal fin ray; no (rarely one or two) scales on predorsal midline.
Lateral profile of body with slight convex curve from first dorsal fin origin to moderately slender caudal peduncle; distinct postorbital notch above and behind each eye and faint furrow across nape at rear of interorbital space; rostral process broadly concave or with very broad medial notch and nearly smooth anterior edge terminating with moderately small triangular spine at each apical corner; predorsal space usually naked or with few large scales on periphery.
