Trichomycterus trefauti
differs from all other known members of the sub-family Trichomycterinae by the autapomorphic presence of ann elliptical, vertically elongated, brown spot, at caudal-fin base (
vs.
without elliptical spot at caudal-fin base), and the combination of homogeneously gray color pattern (
vs.
yellowfish, presence of stripes or or bands, or lack of color pattern), first pectoral-fin ray prolonged as a filament (
vs.
not prolonged), subterminal mouth (
vs.
inferior or terminal mouth), two supraorbital pores at interorbital space (
vs.
one supraorbital pore at mesial line), caudal fin truncate with attenuated edges (
vs.
caudal fin rounded), pelvic fins covering anus and urogenital openings (
vs.
not covering), interorbital space very wide 39.8-45.9% HL(
vs.
more or less than 39.8-45.9% HL), maxillary barbels very long 84.2-93.0% HL (
vs.
more or less than 84.2-93.0% HL), rictal barbels very long 67.6-74.3% HL (
vs.
more or less than 67.6-74.3%HL).

Estimates based on models
Phylogenetic diversity index (Ref.
82804
): PD
50
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00851 (0.00355 - 0.02043), b=2.93 (2.74 - 3.12), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245
).
Trophic level (Ref.
69278
): 3.2 ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref.
120179
): Low, minimum population doubling time 4.5 - 14 years (Assuming Fec < 100).
Fishing Vulnerability (Ref.
59153
): Low vulnerability (10 of 100).
