This species is known from the type locality (Boracéia) and from Atibaia, in the state of São Paulo, Brazil. It has been recorded around 800m asl.
Habitat and Ecology
It occurs in leaf-litter and low vegetation in primary and secondary forest, where it presumably breeds by direct development. It has not been recorded outside forest habitat.
The population status of this species is unknown, as it is only known from a few specimens from each locality.
There are no major threats to its habitat at present, although palm trees are collected in the Boracéia locality, potentially degrading its habitat by opening up the forest canopy.
Both of this species' known localities are within protected areas.
Red List Status
Data Deficient (DD)
Listed as Data Deficient in view of continuing uncertainties as to its extent of occurrence, status and ecological requirements.
