Neoplecostomus sp. A

Fig. 4I

Distribution.

Upper rio Santo Antônio, rio Doce basin.

Diagnosis.

Neoplecostomus sp. A differs from Neoplecostomus sp. B by the maxillary barbels poorly developed; premaxillary teeth and dentary with separate cusps and large concavity between them; lateral and central cusps with similar size; no developed papillae between branches of dentary; plates between dorsal and adipose fin meeting on the back of the dorsum.

Remarks.

In this study, we refer Neoplecostomus sp. A such as a putative new species from the rio Doce basin, due to differences in morphology between this species and another from the rio Doce basin such as N. doceensis , and N. pirangaensis .
