型态特徵 | 形态测量图
背的软条 (总数): 9; 臀鳍软条: 26 - 30; 脊椎骨: 30 - 31. This species is distinguished from its congeners, except T. anostomus, by having only 1 (vs. 2) conspicuous humeral mark; differs from T. anostomus by having a terminal mouth (vs. subsuperior mouth); differs from T. anostomus, T. araguaiensis by the number of gill rakers of the first gill arch, lower 12-13 and upper 8-9, limbs (vs. 17-20 and 10-12 respectively); differs from all congeners, except T. anostomus, T. denticulatus, T. juruena, by having principal dentary teeth 5-6 (vs. 4) and with thinner and sharper teeth (vs. more robust teeth); differs from T. denticulatus by the numbe of scale rows between lateral line and dorsal-fin origin 6 (vs. 7); differs from T. argenteus by the number of predorsal scales 8 (vs. 11-17); differs from T. carvalhoi by the presence of a rounded dark mark on the caudal peduncle (vs. a lozenge-shaped dark mark); differs from T. rarus by the absence of dark longitudinal stripes on the trunk (vs. presence); differs from T. georgiae, T. rarus by the scale rows between lateral line and pelvic-fin origin 3.5 (vs. 4.5-5.5); differs from T. ommatus by the number of maxillary teeth 2-5 (vs. 8-7) and by having the mark centered on caudal peduncle (vs. mark limited to posterior portion of caudal peduncle) (Ref. 124043).
