Psalidodon sp.

Fig. 3P

Distribution.

Upper rio Paraúna, rio São Francisco basin, and upper rio Santo Antônio, rio Doce basin.

Diagnosis.

Psalidodon sp. can be distinguished from its congeners from the study area, except of P. rivularis, by higher body anteriorly to dorsal fin origin; from A. rivularis by having premaxilla slightly in front of dentary in lateral view; five narrow teeth aligned in the inner series of premaxillary bone; two narrow vertical lines of chromatophores surrounding border of abdominal scales; small hooks in pectoral and anal fins in mature males.

Remarks.

In this study, we refer Psalidodon sp. such as putative new species from the study area, due to differences in morphology and color pattern between this species and another Stethaprioninae from Southeastern Brazil river basins, such as P. fasciatus, P. rivularis, A. scabripinnis, and A. turmalinensis .
