Etymology: Trichomycterus: Greek, thrix = hair + Greek, mykter, -eros = nose (Ref. 45335); pauciradiatus: Derived from the Latin pauci (few) and radiatus (with rays), in reference to the reduced number of pelvic-fin rays.

简单描述
检索表 | 型态特徵 | 形态测量图
背的软条 (总数) : 10 - 12; 臀鳍软条: 9; 脊椎骨: 36 - 38. Differs from all other members of the genus by possessing four pelvic-fin rays. Similar to Trichomycterus reinhardti by having a unique color pattern consisting of a broad dark brown stripe on the flank, dorsally bordered by a bright yellow zone without dark marks; but differs from Trichomycterus reinhardti by having a more slender body (body depth 12.6-15.1% SL) and a shorter preorbital length (25.7-39.3% HL) (Ref. 57604).
Body shape (shape guide): elongated.
藉由持有四个腹鳍鳍条有别于本属的所有其他成员。 在侧面上藉由有一个类似 莱因氏毛鼻鲶〔Trichomycterus reinhardti〕 包含一条宽的深褐色的斑纹独特的彩色斑纹, 背面接壤了一个鲜黄色的区域没有深色的标志; 但是藉由有一个有别于 莱因氏毛鼻鲶〔Trichomycterus reinhardti〕 更细长的身体 (体高 12.6-15.1% SL) 与较短的眶前骨长度 (25.7-39.3% HL).(参考文献 57604)
