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).
