Diagnosis. Lateral profile of body with nearly straight taper from rear of first dorsal fin to moderately shallow caudal peduncle; distinct postorbital notch above and behind each eye and faint furrow across nape at rear of interorbital space; rostral process with broad medial notch and nearly smooth anterior edge on each rostral lobe to moderately large, triangular spine at apical corner; lateral line with 56–60 pored scales; 3 or 4 scales above lateral line and about 14–16 scales below lateral line; first dorsal fin with 9 spines, second slightly longer than first, third and subsequent spines progressively shorter, second dorsal fin with 16 rays; anal fin with 16 rays; pectoral fins reaching about third or fourth anal fin ray, first free pectoral fin ray almost reaching tip of interconnected portion of fin above, extending distinctly past tip of pelvic fin, first free ray longer than pectoral fin. Distal half of caudal fin red ventrally and grey above, basal half mostly white; inner surface of pectoral fin black with dark pink base and edges; outer surface similarly blackish with reddish basal and ventral margins and free rays.
