Diagnosis: 33-43 (usually 36-40) scales in longitudinal series on flanks, and 2-5 scales on caudal fin base; 12-17 (usually 13 or 14) in rearward transverse series; body pigmentation usually dark with a broad, dark band on flanks, from pectoral-fin base towards caudal-fin base (Ref. 57413). No prominent dark spot on dorsal part of pectoral fin base (Ref. 57413), if dark pigment present, not distinct from pigment on nape (Ref. 81660). Sensory papillae on upper rear field of opercle form a forked row (Ref. 81660).
