Description synthétique
Clés d'identification | Morphologie | Morphométrie
Distinguished from Trichomycterus therma by having prepelvic length 56.6-57.6% of SL (vs. 58.7-61.0); head width 17.4-18.9% SL (vs. 19.1-22.8); and submaxillary barbel length 43.3-54.8% SL (vs. 23.9-37.5). Shares with Trichomycterus corduvensis for having the shape of maxilla, which has anterior process enlarged and equal to, or longer than the main axis of the bone and with an anterolateral orientation (Ref. 72406).
