Tetragonopterus araguaiensis Silva, Melo, Oliveira & Benine, 2013: 1613  –1631 (original description; type locality: “Brazil, Goiás, Aruanã, Rio Araguaia, Amazon basin).

Diagnosis. Tetragonopterus araguaiensis  is distinguished from all congeners except T. anostomus  by having 18–20 gill rakers on the lower limb and 10–12 gill rakers in the upper limb of the first gill arch (vs. 12–14 and 8–10).

Tetragonopterus araguaiensis  differs from T. anostomus  by having a terminal mouth (vs. subsuperior mouth) and by having two conspicuous humeral marks (vs. only one conspicuous humeral mark). It differs from T. anostomus  , T. kuluene  , T. juruena  and T. denticulatus  by the presence of 4 principal dentary teeth (vs. 5–6) and also by having larger and more robust teeth (vs. thinner and sharper teeth). Tetragonopterus araguaiensis  differs from T. argenteus  by having 7–9 predorsal scales (vs. 11–17); it differs from T. carvalhoi  by having a rounded mark on caudal peduncle (vs. a lozenge-shaped mark); it differs from T. ommatus  by having 0–2 teeth on the maxilla (vs. 7–8 teeth) and by having a centered mark on the caudal peduncle (vs. mark limited to the posterior portion of the caudal peduncle). Tetragonopterus araguaiensis  differs from T. rarus  and T. georgiae  by the presence of 3.5 scale rows between lateral line and pelvic-fin origin (vs. 4.5–5.5). Finally, T. araguaiensis  differs from T. rarus  by the absence of longitudinal dark stripes on the trunk (vs. presence of stripes).

Description. A detailed description of Tetragonopterus araguaiensis  was recently provided by Silva et al. (2013).

Distribution. Tetragonopterus araguaiensis  is only known from the middle portion of the Rio Araguaia ( Fig. 2 b).
