Diagnosis. Lateral profile of body with slight convex curve from posterior part of first dorsal fin base to moderately narrow caudal peduncle; narrow but distinct postorbital notch above and behind each eye and faint furrow across nape at rear of interorbital space; rostral process with broad to deep medial notch and nearly straight to slightly curved anterior edge on each rostral lobe to triangular spine of moderate size at apical corner; lateral line with 58 to 61 pored scales; 3 scales above lateral line and about 14 to 17 scales below lateral line; first dorsal fin with 9 spines, second distinctly longer than first, barely longer than third, subsequent spines progressively shorter, second dorsal fin with 15 or 16 rays; anal fin with 15 (rarely 14 or 16) rays; pectoral fins reaching about fourth or fifth anal fin ray, first free pectoral fin ray reaching to between anus and base of third anal fin ray, not or just reaching tip of pelvic fin. Broad red band just distal to middle of caudal fin with broad ventrally tapering pink margin and transverse red band basally; inner surface of pectoral fin dark greenish brown with large black patch covering ventral third to half of fin from base to distal margin except for fine red margin dorsally and distally and broad red margin ventrally, prominent white spots scattered over all but red areas on fin.
