Distinguished from all congeners in having a thick transverse skin flap between the pelvic fins. Further differs by the following combination of characters: presence of eight or nine paired ribs, reduced pigmentation, and eyes reduced to small ovoid dots. Shares features commonly observed among troglomorphs, yet is distinguished from troglobitic Trichomycterinae in having the maxillary barbel extending to the anterior pectoral-fin margin, nasal barbels reaching the opercular odontodes, three supraorbital pores on the head, eight pectoral-fin rays and the first ray prolonged as a filament, tip of adpressed pelvic-fin not reaching anal-fin origin, 39-40 vertebrae, eight to 13 opercular odontodes, 14-15 interopercular odontodes (Ref. 55665).
在有一个方面与所有的同类区分了在腹鳍之间的厚横跨的皮褶。 进一步不同之处为下列的组合特征: 有八或九根成对的肋骨,缩小的颜色了，而且眼缩小成小的卵形点了。 分享通常在 troglomorphs 之中被观察, 然而被与穴居的 Trichomycterinae 区分的特征有颚的延伸至前面的胸鳍边缘的触须,鼻骨触须达到鳃盖齿, 三个眶上的孔在头部上，延长的八个胸鳍鳍条与第一个鳍条作为一个丝状突起, 紧贴腹鳍的顶端不达成臀鳍起源， 39-40个脊椎骨，八到 13个鳃盖齿, 14-15个间鳃盖骨齿.(参考文献 55665)
