Diagnosis. Lateral profile of body with slight convex curve from first dorsal fin origin to moderately slender caudal peduncle; distinct postorbital notch above and behind each eye and faint furrow across nape at rear of interorbital space; rostral process broadly concave or with very broad medial notch and nearly smooth anterior edge terminating with moderately small triangular spine at each apical corner; lateral line with 55–57 pored scales; about 16 or 17 scales below lateral line; predorsal space usually naked or with few large scales on periphery; first dorsal fin with 9 spines, second spine slightly longer than first and slightly longer or subequal to third, subsequent spines progressively shorter, second dorsal fin with 13 or 14 (rarely 15) rays; anal fin with 14 (rarely 13 or 15) rays; tips of pectoral fins reaching base of about tenth to fourteenth anal fin ray, first free pectoral fin ray reaching base of second anal fin ray. Distal four-fifths of caudal fin red with dorsally tapering narrow pink marginal band and broad reddish band at base; inner surface of pectoral fin yellowish green with large oval black spot adjacent posterior edge on basal half of fin and several curved broad bright blue transverse and marginal bands irregularly interconnected, elongate white spots encircling black spot just within its periphery.
