简单描述
型态特徵 | 形态测量图
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).
身体细长的。 背部与腹的颜色强烈地对比; 点与破折线在上半部上不存在; 在尾柄的后面三分之一上的深色的腹鞍状斑; 在顶端与经过中间的尾鳍突出的深色条纹。 眼相当狭窄; 上眼睑有灰白的裸露区块。 尾柄延长 (18.9-21.8% TL) 。 细齿非常密集，非常细的，和娇弱的, 排列成贫乏地定义纵列。 侧面的斑纹基底在或下面些微地第二背鳍棘向前; 它的在后部分支几乎达到第二背鳍鳍的鳍游离后端; 中央的尾鳍斑纹不存在; 尾部基底的斑纹非常长又超过 7% TL 的手指。 Monospondylous 中心 37-38.(参考文献 45056)
