Australoheros sp.

Fig. 5E

Distribution.

Upper rio Santo Antônio, rio Doce basin.

Diagnosis.

Australoheros sp. differs from A. mattosi by having XVIII+7 dorsal fin rays; VIII+7 anal fin rays.

Remarks.

In this study, we refer Australoheros sp. such as putative new species due to differences in morphology between it and another from rio Doce basin, since A. perdi and A. ipatinguensis seems to be restricted to small areas such as lagoons and small rivers in the rio Doce basin. However, a higher number of specimens with difference sizes is needed and a taxonomic review of the cichlid Australoheros genus as well.
