Trichomycterus sp. A

Fig. 4C

Distribution.

Upper rio Santo Antônio, rio Doce basin.

Diagnosis.

Trichomycterus sp. A is distinguished from its congeners of the study area by the spotted body due to high concentration of large maculae with no defined shape; caudal fin strongly truncated; eight branchiostegal rays; few dorsal procurrent rays (14 or 15).

Remarks.

In this study, we refer Trichomycterus sp. A such as a putative new species from the rio Doce basin, due to differences in morphology and color pattern between this species and another with similar color pattern from Southeastern Brazil river basins such as T. auroguttatus, T. albinotatus, T. brasiliensis group, T. caipora, T. argos, T. novalimensis, and T. rubiginosus .
