Neoplecostomus sp. B

Fig. 4J

Distribution.

Upper rio Paraúna, rio São Francisco basin.

Diagnosis.

Neoplecostomus sp. B differs from Neoplecostomus sp. A by the maxillary barbels developed; premaxillary teeth and dentary with close cusps; median cusp more developed than lateral one; plates between dorsal and adipose fin not meeting.

Remarks.

In this study, we refer Neoplecostomus sp. B such as a putative new species from the rio São Francisco basin, due to differences in morphology between this species and another from rio São Francisco basin such as N. franciscoensis .
