简单描述
检索表 | 型态特徵 | 形态测量图
背棘 (总数) : 0; 背的软条 (总数) : 26; 臀棘: 0; 臀鳍软条: 40; 脊椎骨: 67. Two terminal bulbs separated by a short interspace, shorter than length of distal bulb. Barbel 68% SL. Terminal filament long (20%), with a series of 5 long branches beginning a short distance (a distal bulb length) from bulb, all with small bulblets, none of which approaches the diameter of the filament. All branches with 1 or more short branches. Stem axis peppered with melanophores; lightly pigmented on axis between bulbs and in proximal part of filament. Number of middorsal paired spots under skin uncertain (obscure and diffuse in holotype) (Ref. 11333).
被一个短分开的二个末端的球茎的间隔, 末稍球茎的短于长度。 触须 68% SL。 末端的丝状突起长的 (20%), 有一系列的开始来自球茎的短的距离 (末稍球茎长度),全部有小的球茎的 5个长的分支, 没有那一个接近丝状突起的直径。 所有的分支 1 或更多短的分支。 茎轴布满了黑色素细胞; 颜色很淡轴之上在球茎之间与在丝状突起的近端部份中。 在皮肤下面的背面中央成对的斑点的数字不确定的 (使与阴暗扩散的在 holotype 中).(参考文献 11333)
