Habitat and Ecology
This species is found in thick leaf-litter in Atlantic forest, where it is active by day, with the males calling from exposed positions in the leaf-litter. It is presumed to breed by direct development.
It is locally abundant.
This species is threatened by the substantial deforestation and fragmentation that the Atlantic forest has been subject to 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 not known from any protected areas.
