Dorsal spines (total): 13-15; Dorsal soft rays (total): 14-16; Anal spines: 3-3; Anal soft rays: 10-11. 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).
Description: body (very) deep (Ref. 52307, 53405), its depth 44.4-52.2% of standard length (Ref. 53405). Frontal profile straight to concave (Ref. 52307). Outer jaw teeth bicuspid, outer jaw teeth and posterior pharyngeal teeth tricuspid; micro-gillrakers present; scales cycloid (Ref. 53405). Caudal fin slightly rounded (Ref. 52307).
