This species is known only from the Serra dos Orgãos in south-eastern Brazil, at about 1,200m asl. There has not been sampling outside its range, so it might have a wider distribution than is currently known.
Habitat and Ecology
It occurs on vegetation near waterbodies in clearings in primary and secondary forest, but has not been recorded outside forest. It breeds in bromeliads, and the larvae develop inside these.
It is very common within its very small range.
If it is found to occur outside its known range within a protected area it might be threatened by habitat loss or degradation.
The known range of this species is wholly within Parque Nacional da Serra dos Orgãos.
