South America: Rio Tocantins, various locations within the Amazon basin, and the southern and southwestern portions of the Rio Orinoco basin. Reports of T. quadrifilis from the Rio Orinoco system are considered herein to refer to T. wallacei, which is the only member of the genus known to occur in this river basin.

Short description Bestämningsnycklar | Morfologi | Morfometri

Diagnosis: Distinguished from T. quadrifilis in the alignment of the lateral margins of the head in the region from the anterior margin of the orbit to the posterior limit of the opercle (running approximately in parallel from ventral view vs. diverging laterally, respectively); in the body width at the pectoral-fin insertion as a proportion of the head width at the posterior margin of the orbit (0.99-1.10 vs. 1.17-1.25, respectively); in the distance from the tip of the snout to the anal fin origin (0.29-0.32 of SL vs. 0.33-0.36 of SL, respectively); and in the position of the anterior termination of the gill opening (one orbital diameter posterior of the transverse plane running through the posterior margin of the orbit vs. positioned in the transverse plane running through the center of the orbit, respectively) (Ref. 56964).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00741 (0.00341 - 0.01611), b=3.06 (2.88 - 3.24), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trofisk nivå (Ref. 69278): 3.4 ±0.4 se; based on size and trophs of closest relatives

Resiliens (Ref. 120179): Hög, lägsta populationsfördubblingstid mindre än 15 månader (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (15 of 100).
