Etymology: Trichomycterus: Greek, thrix = hair + Greek, mykter, -eros = nose (Ref. 45335); caudofasciatus: Derived from the Latin cauda (tail) and fasciatus (with bars), referring to the caudal-fin color pattern.

Short description Bestämningsnycklar | Morfologi | Morfometri

Mjukstrålar i ryggfenan (totalt) : 10 - 11; Mjukstrålar i analfenan: 9; Ryggkotor: 35 - 37. Distinguishable from all other species of the genus by the combination of the following characters: 7-8 pectoral-fin rays, long filamentous first pectoral-fin ray (about 50-70% pectoral-fin length), 10-20 opercular odontodes, 30-52 interopercular odontodes, opercular patch of odontodes wide, and 6-7 branchiostegal rays. Can be easily distinguished from T. alternatus, T. longibarbatus and T. pantherinus by possessing a single median last supraorbital pore (vs. paired pore). Distinguished from all other species of the genus from the Brazilian Shield River basins by having a unique color pattern of four gray bars on the caudal fin (Ref. 53352).

Inhabits both turbid and clear water with shallow water (40-100 cm deep). Sometimes found swimming in daylight, but mostly collected under marginal vegetation or under vegetal debris on the bottom (Ref. 53352).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00977 (0.00400 - 0.02388), b=3.04 (2.84 - 3.24), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trofisk nivå (Ref. 69278): 3.1 ±0.4 se; based on size and trophs of closest relatives

Resiliens (Ref. 120179): Låg, lägsta populationsfördubblingstid 4,5-14 år (Assuming Fec < 100).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
