Characidium sp. B

Fig. 3D

Distribution.

Upper rio Santo Antônio, rio Doce basin.

Diagnosis.

Characidium sp. B differs from its congeners from the study area by predorsal length less than 45% of total length; lateral vertical bars absent or without defined shape; dark maculae on caudal fin not forming defined bands.

Remarks.

In this study, we refer Characidium sp. B such as a second 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. alipioi, C. grajahuense, C. lagosantense, and C. lauroi .
