. Body compressed and elongate; greatest body depth usually located anterior to dorsal-fin origin. Dorsal profile of head between vertical through posterior nostril and tip of supraoccipital spine straight or slightly convex. Profile of body convex from tip of supraocciptal spine to base of last dorsal-fin ray, and straight from that point to adipose-fin origin. Ventral profile of body slightly convex from vertical through posterior nostril to pectoral-fin insertion, and nearly straight from that point to anal-fin origin. Body profile along anal-fin base posterodorsally slanted. Caudal peduncle elongate and nearly straight to slightly concave along both dorsal and ventral margins.

Premaxilla with two tooth rows; outer row with three pentacuspid teeth with central cusp longer. Five teeth in inner premaxillary row; teeth gradually decreasing in length from first towards fourth teeth with last tooth distinctly smaller: teeth with five to seven cusps with central cusp twice as long and broad as other cusps. Maxilla with two or three (usually two) teeth with tree to five cusps and central cusp longest. Four anterior-most dentary teeth larger, with five or seven cusps, followed by one medium-sized tooth with five cusps, and then four or five teeth with one to three cusps. Central cusp in all teeth two to three times as long and broad as other cusps. All cusp tips slightly curved posteriorly towards inside of mouth (

Dorsal portion of body densely pigmented in larger specimens. Scales on midlateral surface of body bordered with dark brown chromatophores forming reticulate pattern. Body with black, pigmented, midlateral stripe extending from humeral region to base of middle caudal-fin; faint dark pigmentation present of middle caudal-fin rays. Midlateral body stripe expanded dorsally and ventrally proximate to caudal-fin base and forming small caudal spot. Single black, narrow, vertically-elongate humeral spot present with dorsal portion of spot wider. Spot located over second to fourth lateral-line scales and extending over 2 or 3 horizontal series of scales, including lateral line. Fins with scattered dark chromatophores (
