Pareiorhaphis sp.
Distribution.
Upper rio Paraúna, rio São Francisco basin.
Diagnosis.
Pareiorhaphis sp. differs from Pareiorhaphis scutula by the abdomen without plates; from P. scutula and P. vetula by the pectoral, pelvic and anal fins with clear color; dark caudal with clear borders. Pareiorhaphis sp. can still be distinguished from Pareiorhaphis vetula by inferior lip with developed maxillary barbels; urogenital papilla with normal size, not elongated.
Remarks.
In this study, we refer Pareiorhaphis sp. such as a putative new species from the rio Doce basin, due to differences in morphology between this species and another from rio Doce basin such as P. nasuta, and P. proskynita .
