deskripsi pendek
Morfologi | Morfometrik
duri punggung lunak (Keseluruhan (total)): 7-8; Sirip dubur lunak: 6 - 7; vertebrata, bertulang belakang: 37. Differs from its congeners by having large head 23.8-26.8% SL, which is proportionally the largest head in any Trichomycteridae. Additional diagnostic characters that distinguished this species from most or all of its congeners are the following: almost entirely cartilaginous second hypobranchial (with only vestigial ossification; mesially expanded palatine ossification; narrow and falciform cleithrum; absence of a proximal posterior concavity on the third ceratobranchial. Can be further distinguished from all congeners, except Trichomycterus stawiarski and T. sp. C, by having rigid spine-like morphology of individual procurrent rays of the caudal fin, extension of the dorsal caudal-fin procurrent rays series (extending for ten neural spine tips), and presence of ten or eleven branchiostegal rays. Dorsal fin situated on a concavity on dorsal profile of trunk, short caudal peduncle (15.4-19.7% SL) and first anal-fin ray base posterior to the vertical through the base of the last dorsal-fin ray are other useful characters for identification shared with various other species of Trichomycterus (Ref. 75005).
Feeds on larvae of Diptera (Simulidae), Ephemeroptera and Trichoptera, indicating benthic feeding habits (Ref. 75005).
