Habitat and Ecology
It has been found in the margins of temporary ponds, in which it makes a foam nest, and in swampy areas in moist rainforest, and in forest edges. It can tolerate slight disturbance to its habitat, but it does not occur in more degraded areas and is not found outside forest.
It is relatively common in suitable habitat.
The major threats to this species are probably related to habitat loss due to fire and human settlement.
It occurs in Parque Estadual da Serra do Brigadeiro.
