Habitat and Ecology
This species is found in Atlantic Forest remnants. Individuals are usually found on the forest floor, far from water bodies. Breeding takes place by larval development, with terrestrial larvae. It seems to prefer pristine areas, but is also present in forest fragments (Dixo and Verdade, 2006).
This species is common in suitable habitat, being the second most abundantly collected species in Reserva Biológica do Morro Grande (Dixo and Verdade, 2006).
The Atlantic Forest has been subject to substantial deforestation and fragmentation due to historical logging and ongoing large-scale clearance for cattle pasture, and crops such as sugar cane, coffee, and exotic trees, as well as for smallholder agriculture.
It is known from Parque Estadual Intervales and Reservas Biológica de Paranapiacaba and Morro Grande.
