Short description Morphology | Morphometrics

Dorsal spines (total): 2; Dorsal soft rays (total): 7; Anal spines : 1; Anal soft rays : 6. 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).
