简单描述
型态特徵 | 形态测量图
背棘 (总数): 2; 背的软条 (总数): 7; 臀棘 1; 臀鳍软条: 6. Trichomycterus trefauti differs from all other known members of the sub-family Trichomycterinae by the autapomorphic presence of ann elliptical, vertically elongated, brown spot, at caudal-fin base (vs. without elliptical spot at caudal-fin base), and the combination of homogeneously gray color pattern (vs. yellowfish, presence of stripes or or bands, or lack of color pattern), first pectoral-fin ray prolonged as a filament (vs. not prolonged), subterminal mouth (vs. inferior or terminal mouth), two supraorbital pores at interorbital space (vs. one supraorbital pore at mesial line), caudal fin truncate with attenuated edges (vs. caudal fin rounded), pelvic fins covering anus and urogenital openings (vs.not covering), interorbital space very wide 39.8-45.9% HL(vs. more or less than 39.8-45.9% HL), maxillary barbels very long 84.2-93.0% HL (vs.more or less than 84.2-93.0% HL), rictal barbels very long 67.6-74.3% HL (vs.more or less than 67.6-74.3%HL).
Trichomycterus trefauti 有别于子该科 Trichomycterinae 的所有其他已知成员藉由 autapomorphic 有 ann 椭圆形,垂直地延长, 褐色斑点, 在尾鳍基底 (vs. 没有椭圆的斑点 在尾鳍基底), 与同种灰色彩色斑纹 (vs. yellowfish, 有斑纹或者或者条纹, 或没有彩色斑纹) 的组合第一个延长的胸鳍鳍条作为一个丝状突起 (vs. 不被延长的 ) ，接近端位的嘴 (vs.下方的或者端位口), 二個眶上的孔在眼間隔 (vs. 一個眶上的孔在中央的線) ，尾鰭截形有變細邊緣 (vs. 尾鰭圓的) 腹鰭包含的肛門與泌尿生殖孔 (vs. 不覆蓋), 眼間隔非常寬的 39.8-45.9% HL(vs. 約略超過 39.8-45.9% HL), 上頜骨觸鬚非常長的 84.2-93.0% HL(vs. 約略超過 84.2-93.0% HL), rictal 觸鬚非常長的 67.6-74.3ÿÈ% HL.(vs. 約略超過 67.6-74.3%HL)
