Short description Identification keys | Morphology | Morphometrics

Vertebrae: 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).

Biology     Glossary (e.g. epibenthic)

A rheophilic species occurring solely in riffle areas of streams (Ref. 55400). Feeds mainly on young benthic aquatic insects during the day (Ref. 55400).
