簡短描述
檢索表 | 型態特徵 | 形態測量圖
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).
與所有的其他種的 Trichomycterus 區分了, 除了 T. castroi, 在有一個方面顯著的, 橫過尾鰭的近端區域的垂直的沒有顏色條紋。 從 T. castroi 在持有超過尾鰭的長度佔領大約 30% 以內的那一條條紋方面可能是進一步區別，而且在背部葉中更顯著作為一個白色的眼狀斑 (vs. 那區域明顯比較寬的, 藉由尾鰭的大約 80% 長度與比較好的清晰作為一個全部) 。 (參考文獻 55400)
描述: 背鰭 iii,2,7. 臀鰭 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).
在溪流的急流區域中獨自地出現的一個急流生物種.(參考文獻 55400) 主要吃幼魚底棲的水生昆蟲在白天期間。 (參考文獻 55400)
