Characidium sp. C

Fig. 3E

Distribution.

Upper rio Santo Antônio, rio Doce basin.

Diagnosis.

Characidium sp. C differs from its congeners from the study area by predorsal length up to 55% of total length; vertical bars always arranged above and below the lateral line in a “y” or “yy” shape; weak of narrow dark band on caudal fin.

Remarks.

In this study, we refer Characidium sp. C such as a third 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 C. cricarense and C. litorale .
