Harttia sp.

Distribution.

Upper rio Santo Antônio, rio Doce basin.

Diagnosis.

Harttia sp. differs from H. intermontana by inferior region of orbit straight; compressed and narrow plates with developed odontodes in the dorsal and ventral region of caudal peduncle.

Remarks.

In this study, we refer Harttia sp. such as a putative new species from the rio Doce basin, due to differences in morphology between this species and another from Southeastern Brazil river basins such as H. carvalhoi, H. garavelloi, H. leiopleura, H. loricariformis, H. novalimensis, and H. torrenticola .
