Diagnosis

Diagnosis: last simple dorsal ray ossified and as long as head in largest individuals, ossified at base, ossified portion shorter than head (60-85% of head length); lips poorly developed, without mental lobe; 9 dorsal fin branched rays; scale formula 3.5-4.5/23-26/4.5; 2 scales between lateral line and pelvic-fin base; 12 scales around caudal peduncle; 1-3/10-11 gill rakers on first gill arch (Ref. 2940, 81282).

Description: mouth inferior; distal margin of dorsal fin slightly concave; D:IV,9; A:III,5; P:15-16; V:I,8-9 (Ref. 2940, 81282).

Coloration: live specimens are greyish, with scales on sides slightly tinged with yellow-orange, belly white; fins yellowish-pink, except for the dorsal fin which is dark grey; upper and lower margins of caudal fin blackish (Ref. 2940, 81282).
