简单描述
型态特徵 | 形态测量图
背的软条 (总数): 24; 臀鳍软条: 38; 脊椎骨: 68. Two terminal bulbs separated by an interspace, 1.4-3.6 times the length of distal bulb. Barbel length mostly 36-65% SL. Terminal filaments 7-10, arising together from distal bulb or from a short stem; all prominent bulblets of various sizes and with side branches distally; 1 filament a little thicker than others and usually forked. Pigment in filament axes variably present or absent. Distal bulb small, ovoid, usually with an abruptly narrowed distal end, 1.5- 3 times proximal-bulb length, which is very small. Axis of stem and between bulbs usually pigmented, variably light or dark, sometimes unpigmented. A black spot almost always present at proximal end of distal bulb; usually partially capping base of bulb. External chevron-shaped or roundish striated areas on stem pigmented or not. Middorsal paired spots between occiput and dorsal-fin origin 8, sometimes 7 (Ref. 11333).
被一个间隙分开的二个末端的球茎,1.4-3.6 倍于末稍球茎的长度。 触须长度大部份 36-65% SL。 末端的丝状突起 7-10, 一起从末稍球茎或矮茎出现; 各种不同大小的所有突出球茎与具有支流末梢部地; 1个丝状突起稍微比其它更厚而且通常分岔了。 在丝状突起轴的有颜色易变存在或者不存在。 末稍球茎小的, 卵形体,通常有一个突然地狭窄的末梢部的末端,1.5- 3 倍近端-球茎长度, 是非常小的。 茎的轴而且在球茎之间通常有颜色, 易变淡或深色的, 有时没有颜色。 一个黑色的斑点几乎总是出现在末稍球茎的近侧端; 通常部份地加盖于球茎的基底。 在茎上的外部的锯齿形或圆的有条纹的区域有颜色或没有颜色的。 在后脑部与背鳍起点 8 之间的背面中央的成对斑点, 有时 7.(参考文献 11333)
