This species is known from two localities: Monte Belo, and Poços de Caldas, both in Minas Gerais State, in south-eastern Brazil, where it has been recorded at around 1,000m asl. Sampling of this area is poor, so it might have a larger distribution than is currently known.
Habitat and Ecology
It occurs in primary and secondary gallery forests on vegetation along rivers, but has not been recorded from anthropogenic habitats. Larvae were found in ponds on the streams margins.
It is a common species.
Mining is the main threat to this species, in particular due to the pollution of its habitat that this activity causes.
It is not known to occur within any protected areas, and conservation and maintenance of its habitat is needed. More research into its extent of occurrence, ecological requirements and population status is also needed, in particular to determine if it occurs outside the two known localities.
