简单描述
检索表 | 型态特徵 | 形态测量图
Body extremely slender. Dorsal and ventral coloration sharply contrasted; fine dark horizontal lines forming series of fine dots and dashes on upper half of body; a dark ventral saddle near middle of caudal peduncle. Head relatively short (usually < 21% TL). Caudal peduncle very elongate (usually > 23% TL). Eyes rather narrow; upper eyelid with pale naked patch. Denticles extremely dense, bristle-like, not arranged in defined rows. Flank-marking base forward of second dorsal-fin spine; its posterior branch longer than anterior branch and extending beyond free rear tip of second dorsal fin; central caudal marking absent. Monospondylous centra 41-45 (Ref. 45056).
身体非常细长。 背部与腹的颜色锐利地对比; 在身体的上半部上的深色细的水平线形成数列细点与破折线; 在尾柄的中央附近的一个深色的腹鞍状斑。 头部相当短的.(通常 <21% TL) 尾柄非常长的.(通常 >23% TL) 眼相当狭窄; 上眼睑有灰白的裸露区块。 细齿非常密集，像刚毛一样的, 不排列成固定的列。 侧面的斑纹基底第二背鳍-鳍棘向前; 它的在后部分支长度超过前面的分支而且延伸超过第二背鳍鳍的鳍游离后端; 中央的尾鳍斑纹不存在。 Monospondylous 中心 41-45.(参考文献 45056)
