Hasemania sp.

Fig. 3L

Distribution.

Upper rio Paraúna, rio São Francisco basin.

Diagnosis.

Hasemania sp. differs from H. nana by having 11-14 branched rays in anal fin and presence of rounded blotch in the base of median caudal fin rays.

Remarks.

In this study, we refer Hasemania sp. such as putative new species and second record from the rio São Francisco basin, due to differences in morphology and color pattern between this species and another from Southeastern Brazil river basins such as H. bilineata , H. crenuchoides , H. nana , and H. uberaba . In the taxonomic revision carried out by Serra (2003) there is no mention of the morphotype. The same have occurred in Vieira et al. (2015) resulting here in the first record of the taxon for the basin.
