Diagnosis

Description: Dorsal fin origin above vent (Ref. 12693), much closer to anal fin origin than to gill slit (Ref. 52193). Eyes before angle of jaw (Ref. 52193). Teeth bands broad without gasps between teeth rows; teeth small, inconspicuous, multiserial, forming broad continuous bands on jaws and vomer; vomerine tooth-band extending as far back as bands of upper jaw but more pointed posteriorly (Ref. 4832, 52193).

Colouration: Dorsal body colour uniform (Ref. 79840). Olive to dark bluish-brown dorsally, lighter ventrally from jaw to anus (Ref. 3971, 52193). Mature adults change to bronzy silver (Ref. 52193).
