Habitat and Ecology
This species is found in thick leaf-litter in Atlantic forest. It is active by day, and has been observed from November to April (though it is active mainly from December to February). 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.
This species is not known from any protected areas.
