Short description Morphology | Morphometrics

Dorsal soft rays (total): 9; Anal soft rays: 24 - 28; Vertebrae: 31. This species is distinguished from all its congeners, except T. ommatus, T. kuluene, by the maxillary teeth 4-6 (vs. 1-4); differs from T. ommatus with the dark mark centered on caudal peduncle (vs. a vertically-oriented mark limited to posterior portion of peduncle); differs from T. anostomus, T. denticulatus, T. kuluene by the principal teeth in dentary 4 (vs. 5-6) and by having more robust teeth on the dentary (vs. thinner, sharper teeth); differs from T. anostomus with a terminal mouth (vs. subsuperior mouth); differs from T. anostomus, T. kuluene by the conspicuous humeral marks 2 (vs. 1); differs from T. denticulatus by the number of scale rows between lateral line and dorsal-fin origin 6 (vs. 7); differs from T. anostomus, T. araguaiensis by the number of gill rakers of the first gill arch 7-8 + 10-12) (vs. 10-12 + 17-20); differs from T. argenteus by the predorsal scales 8 (vs. 11-17); differs from T. carvalhoi by having a rounded dark mark on the caudal peduncle (vs. lozenge-shaped) (Ref. 124043).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = No PD50 data   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02188 (0.00852 - 0.05619), b=3.00 (2.78 - 3.22), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.1   ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
