This species is distinguished by the following characters pectoral fin 16-17 rays; nape and posterior part of occipital region covered by cycloid scales with the scaled area extending anteriorly to around a vertical line through posterior margin of preopercle or a little posterior to this line; longitudinal scales 29-34, predorsal scales 5-13; total vertebrae 26; cephalic sensory pore system usually with B´, C, D(S), E, F, H´, K´, L´, M´, N, and O´, but often lacking one or both side(s) of pore C; cheek with transverse rows of sensory papillae. Colouration: when preserved, the lateral and dorsal sides of body with no mesh-like markings, obscure markings on cheek, and upper half of pectoral fin with dark brown band vertically across proximal part; when fresh, pectoral-fin base with a bright white vertical band reaching near bottom of fin (Ref. 125663).
