This species is known only from Horto Florestal de Santa Cruz, Itaguaí Municipality, in the state of Rio de Janeiro, south-eastern Brazil. The only known site is very close to sea level.
Habitat and Ecology
It was probably originally a primary forest species, but now lives only in secondary forest, since this is all that remains within its range. It is usually found near ponds in forest. The eggs are laid in a foam nest on the surface of temporary pools.
It has a very small, but stable, population.
The major threats are habitat loss due to conversion of habitat to eucalyptus plantations, and human disturbance.
It occurs in the Florestal Nacional Mario Xavier protected area, but this is poorly protected and in need of improved management.
