简单描述

背的软条 (总数) : 25 - 26; 臀鳍软条: 37 - 38; 脊椎骨: 68. Barbel with two terminal bulbs, distal one bearing tuft of filaments (Ref. 37473); separated by a long interspace, 1.7-3.8 times the length of distal bulb in specimens larger than 7 cm SL. Barbel length 31-82% SL except when developing. Terminal filaments short, 3-7 (less than 10% SL) without prominent bulblets, arising together from distal bulb or from a short distal stem; 1 filament thicker and longer than the rest. Some or all filaments with pigmented axes. Distal bulb ovoid , only slightly longer than wide, 1.2-2.5 times proximal-bulb length. Axis of stem and between bulbs variably pigmented; a black spot or cap almost always formed at proximal end of distal bulb. External chevron-shaped or roundish striated areas on stem unpigmented. Middorsal paired spots between occiput and dorsal-fin origin 7 or 8, sometimes 9 (Ref. 11333).
触须有两个末端的球茎, 末梢部的生长着丝状突起的簇;(参考文献 37473) 藉着一个长间隙分开,1.7-3.8 在标本大于 7 公分 SL 中倍于末稍球茎的长度。 除了当发展以外的触须长度 31-82% SL。 末端的丝状突起短,3-7(少于 10% SL) 没有突出的球茎, 一起从末稍球茎或短的末梢部的茎出现; 1个丝状突起比较厚而长度超过其他部分。 用着色的轴一些或所有的丝状突起。 末稍球茎卵形体 , 只些微地长度超过宽的,1.2-2.5 倍近端-球茎长度。 茎的轴而且在球茎之间易变地有颜色; 一个黑色的斑点或无边帽几乎总是在末稍球茎的近侧端形成了。 在茎上的外部的锯齿形或圆的有条纹的区域没有颜色。 在后脑部与背鳍起点 7 或 8 之间的背面中央的成对斑点, 有时 9.(参考文献 11333)
