Diagnosis: lower pharyngeal bone about as long as broad, and with anterior lamella shorter than toothed area; median pharyngeal teeth broadened when compared to the lateral teeth; 5-6 series of scales on cheeks; 4.5-6 scales between first dorsal fin spine and upper lateral line; dark vertical bars broader than lighter inter-spaces (Ref. 53405).
