This species is known only from the Serra da Bocaina and the Serra Itatiaia, in Rio de Janeiro and São Paulo States, in south-eastern Brazil, although it might occur more widely. It occurs above 1,200m asl.
Habitat and Ecology
It breeds in bromeliads in montane moist forest, but very little other ecological information is known.
It is known from fewer than 10 specimens, so its population status is not known. No attempts have been made to return to the localities for many years to try to collect the species.
There is very little information regarding potential threats to this species.
Both of the known localities are in protected areas.
