Deuterodon sp.

Distribution.

Upper rio Santo Antônio, rio Doce basin.

Diagnosis.

Deuterodon sp. differs from its congeners from the study area by having five hexacuspidate to heptacuspidate teeth in the inner series of the premaxillae; cusps straight, not forming notch; infraorbital 3 with naked area anteriorly, and below it; low concentration of chromatophores in the infraorbital 3; inconspicuous humeral spot slightly verticalized, straight anteriorly and straight or half-moon shaped posteriorly; 5.5 scales above lateral line; iii+21 anal fin rays.

Remarks.

In this study, we refer Deuterodon sp. such as putative new species from the rio Doce basin, due to differences in morphology and color pattern between this species and another from southeastern Brazil river basins such as D. giton , D. intermedius , and D. taeniatus .
