duri punggung lunak (Keseluruhan (total)) : 9; Sirip dubur lunak: 26 - 33; vertebrata, bertulang belakang: 30 - 31. This species is distinguished from T. anostomus, T. denticulatus, T. juruena, T. kuluene by the principal teeth on dentary 4 (vs. 5-6), and having larger and more robust teeth (vs. thinner and sharper teeth); differs from T. anostomus, T. araguaiensis by the gill-rakers on lower limb of the first gill arch 11-14 (vs. 17-20); differs from T. carvalhoi by the rounded dark mark on the caudal peduncle (vs. lozenge-shaped); differs from T. anostomus by having a terminal mouth (vs. subsuperior); differs from T. anostomus, T. kuluene by the conspicuous humeral marks 2 (vs. 1); differs from T. argenteus by the predorsal scales 7-9 (vs. 11-17); differs from T. franciscoensis by the number of olfactory lamellae 20-40 (vs. 11-17) and by having more robust teeth on dentary (vs. thinner and sharper teeth); differs from T. denticulatus by having humeral marks separated by a single vertical scale row (vs. marks separated by three vertical scale rows); differs from T. rarus by lacking the longitudinal dark stripes on the trunk (vs. presence); differs from T. rarus, T. georgiae by the scale rows between lateral line and pelvic fin origin 3.5 (vs. 4.5-5.5); differs from T. ommatus by the teeth on the maxilla 1-4 (vs. 7-8) and by having a conspicuous dark mark on the caudal peduncle (vs. inconspicuous and limited to the posterior part of the caudal peduncle) (Ref. 124043)

Occurs in creeks with rapidly flowing water over sandy areas and slow flowing water over plant debris (Ref. 12225).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5020 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.02455 (0.01299 - 0.04638), b=2.97 (2.80 - 3.14), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 3.2 ±0.4 se; based on size and trophs of closest relatives

Daya lenting (Ref. 120179): Tinggi, Waktu penggandaan populasi minimum kurang dari 15 bulan (Preliminary K or Fecundity.).

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