簡短描述
型態特徵 | 形態測量圖
背棘 (總數): 0; 背的軟條 (總數): 12-13; 臀棘 0; 臀鰭軟條: 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.
眼被細又透明的皮膚蓋著了。 種有別於亞科 Trichomycterinae 的所有其他已知成員藉由它的組合沒有那兩個腹鰭與肢帶骨, 八或者九主要背鰭鰭條， 37-39個脊椎骨,18-20 肋骨在兩邊上，細長的身體橫著具有一個平的尾柄, 那在後部直的而且些微地背部後方地角尾鰭邊緣, 缺乏明顯的大理石的顏色在身體上與鰭, 它的缺乏 s 脂肪組織的非常厚又多皺紋層在身體上與頭部, 那有在蝶骨裡面的側線管系統的部分, 那壺腹器官沒有皮膚表面的一個廣泛穿孔經由小孔, 與它的最大長度。
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).
採集自 0.5 公尺深，小且清澈的水水流了底部為沙質的地方在海拔大約 3500 公尺。 二件標本的腹部包含了指出此魚種吃, 在土生土長的底棲大型無脊椎動物上至少在部份的雙翅類昆蟲的幼生 (搖蚊與蠓科昆蟲) ，菌絲藻與沙子。 (參考文獻 37038)
