简单描述

脊椎骨: 41. Distinguished from all other species of Trichomycterus, except for T. castroi, in having a conspicuous, vertical unpigmented band across the proximal region of caudal fin. Can be further differentiated from T. castroi in possessing that band occupying about 30% or less than the length of the caudal fin, and being more evident in the dorsal lobe as a white ocellus (vs. that zone distinctly broader, with approximately 80% of the length of the caudal fin and better defined as a whole) (Ref. 55400).
与所有的其他种的 Trichomycterus 区分了, 除了 T. castroi, 在有一个方面显著的, 横过尾鳍的近端区域的垂直的没有颜色条纹。 从 T. castroi 在持有超过尾鳍的长度占领大约 30% 以内的那一条条纹方面可能是进一步区别,而且在背部叶中更显著作为一个白色的眼状斑 (vs. 那区域明显比较宽的, 藉由尾鳍的大约 80% 长度与比较好的清晰作为一个全部) 。 (参考文献 55400)
描述: 背鳍 iii,2,7. 臀鳍 iii,2,5.(參考文獻 55400)
A rheophilic species occurring solely in riffle areas of streams (Ref. 55400). Feeds mainly on young benthic aquatic insects during the day (Ref. 55400).
