簡短描述
檢索表 | 型態特徵 | 形態測量圖
脊椎骨: 76 - 82. Body slender. Dorsal and ventral coloration strongly contrasted; dots and dashes absent on upper half; dark ventral saddle on posterior third of caudal peduncle; prominent dark bands at the tip and through mid caudal fin. Eyes rather narrow; upper eyelid with pale naked patch. Caudal peduncle elongate (18.9-21.8% TL). Denticles extremely dense, very thin, delicate, arranged in poorly defined longitudinal rows. Flank marking base under or slightly forward of second dorsal spine; its posterior branch barely reaching free rear tip of second dorsal fin; central caudal marking absent; finger of caudal base marking very long, more than 7% TL. Monospondylous centra 37-38 (Ref. 45056).
