This species is known only from near Santa Teresa, in the state of Espirito Santo, south-eastern Brazil, at around 650m asl, although it might be more widespread.
Habitat and Ecology
It lives in the leaf-litter on the ground of primary and secondary forest, and breeds by direct development.
It is a common species within its small known range.
The area where the species is found is quite well protected (as a biological reserve), but habitat loss is taking place nearby (where the species might occur), due to creation of wood plantations, smallholder farming, logging, human settlement and tourism.
The biological reserve in which it occurs is the Reserva Biológica Augusto Ruschi.
Red List Status
Near Threatened (NT)
Listed as Near Threatened since although the species is common within its restricted range, and its populations appear to be stable, its Extent of Occurrence is less than 5,000 km2, and the extent and quality of its habitat is declining, thus making the species close to qualifying for Vulnerable.
