简单描述
检索表 | 型态特徵 | 形态测量图
背的软条 (总数) : 24; 臀鳍软条: 39; 脊椎骨: 68. Two terminal bulbs separated by an interspace, 1.2-2.4 times the length of distal bulb. Barbel length mostly 31-71% SL in specimens less than 8 cm; 67-91% SL in larger ones. Terminal filaments short, 4-6 without prominent bulblets, arising together from distal bulb or from a short distal stem; 1 filament thicker and longer than others. Pigment in filament axes variably present or absent. Distal bulb spheroidal to ovoid, not much longer than wide, 1.5-4.3 times proximal-bulb length. Axis of stem usually lightly pigmented, between bulbs unpigmented or lightly pigmented; dark spot present or not 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 8, sometimes 9 (Ref. 11333).
被一个间隙分开的二个末端的球茎,1.2-2.4 倍于末稍球茎的长度。 触须长度大部份在标本的 31-71% SL 少于 8 公分; 在较大的一些中的 67-91% SL。 末端的丝状突起短,4-6 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它。 在丝状突起轴的有颜色易变存在或者不存在。 末稍球茎类似球体的对卵形体, 不是远长过宽的,1.5-4.3 倍近端-球茎长度。 茎的轴通常颜色很淡, 在球茎之间没有颜色或颜色很淡; 深色的斑点在末稍球茎的近侧端呈现。 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 8 之间的背面中央的成对斑点, 有时 9.(参考文献 11333)
