Diagnosis

Diagnosis: body depth 3.9x and head length 3x SL; 32 lateral line scales; lateral line reduced to 5 anterior scales; 11 anal fin branched rays; 14 dorsal fin branched rays; narrow, black longitudinal band interrupted above anal fin, extending from gill cover to middle of caudal peduncle (Ref. 2936, 86396).

Description: round snout, smaller than eye; maxilla not reaching to below anterior eye margin, with 3 teeth at its upper angle; adipose fin absent; each jaw with two rows of teeth, those in outer row bicuspid, those in inner row conical; caudal peduncle 1.5x long than high; (Ref. 2936, 86396).

Coloration: alcohol preserved specimens pal and with brown longitudinal band from gill cover to centre of caudal peduncle where it becomes much paler, the upper margin of this band running through the centres of lateral-line scales; fins colourless (Ref. 2936, 86396).
