简单描述
型态特徵 | 形态测量图
背棘 (总数): 0; 背的软条 (总数): 12-13; 臀棘 0; 臀鳍软条: 11 - 12; 脊椎骨: 37 - 39. Eye covered by thin, transparent skin. Species differs from all other known members of the subfamily Trichomycterinae by the combination of its lack of both the pelvic fins and girdle, eight or nine principle dorsal fin rays, 37-39 vertebrae, 18-20 ribs on each side, the elongate body with a transversely flattened caudal peduncle, the posteriorly straight and slightly posterodorsally angled caudal fin margin, the lack of pronounced marmorated pigmentation on the body and fins, its lack of s very thick, rugose layer of fatty tissue on the body and head, the presence of a portion of the laterosensory canal system within the sphenotic, the lack of an extensive perforation of the skin surface by pores of the ampullary organs, and its maximum length.
眼被细又透明的皮肤盖着了。 种有别于亚科 Trichomycterinae 的所有其他已知成员藉由它的组合没有那两个腹鳍与肢带骨, 八或者九主要背鳍鳍条， 37-39个脊椎骨,18-20 肋骨在两边上，细长的身体横着具有一个平的尾柄, 那在后部直的而且些微地背部后方地角尾鳍边缘, 缺乏明显的大理石的颜色在身体上与鳍, 它的缺乏 s 脂肪组织的非常厚又多皱纹层在身体上与头部, 那有在蝶骨里面的侧线管系统的部分, 那壶腹器官没有皮肤表面的一个广泛穿孔经由小孔, 与它的最大长度。
Collected from a 0.5 m deep, small, clear water stream with a sandy bottom at an elevation of approximately 3500 m. The stomachs of two specimens contained dipteran larvae (Chironomidae and Ceratopogonidae), filamentous algae, and sand indicating that the species feeds, at least in part on autochthonous benthic macroinvertebrates (Ref. 37038).
采集自 0.5 公尺深，小且清澈的水水流了底部为沙质的地方在海拔大约 3500 公尺。 二件标本的腹部包含了指出此鱼种吃, 在土生土长的底栖大型无脊椎动物上至少在部份的双翅类昆虫的幼生 (摇蚊与蠓科昆虫) ，菌丝藻与沙子。 (参考文献 37038)
