Diagnosis

Diagnosis: relatively deep-bodied species with a steep, straight forehead (Ref. 42983, 52307) and short snout (Ref. 52307). Very flat gibbosity, most pronounced in adult males; lower pharyngeal bone with 151 teeth (mean value); usually 5 broad gill rakers on lower limb of first arch (Ref. 42983).

Description: sexes differ only in a somewhat larger adult male with more elongated rays in dorsal and anal fin and no (or only slightly developed) hump on its head (Ref. 52307).

Coloration: both sexes dark gray, with 2 blackish stripes on body that join at caudal peduncle (Ref. 52307).
