This species is known only from the vicinity of the type locality, Restinga da Marambaia, in Rio de Janeiro State, southern Brazil. It has only been recorded around sea level.
Habitat and Ecology
This species occurs on the ground, near ponds on sandy bank vegetation. It creates foam nests on the ground next to temporary pools, and the tadpoles then develop in the pools. It also occurs in sandy dunes along the coast with low vegetation.
It is a common species.
The restricted range of this species makes it more susceptible to threatening processes. Habitat loss due to infrastructure development for human settlement and tourism is a significant threat.
The known range of the species is partly within a high security military area, which affords its habitat good protection. Maintenance of its habitat, since it is only known from one area, is needed. More research into the species' Extent of Occurrence, ecological requirements and population status is needed, in particular to determine if it occurs outside the vicinity of the type locality, as is currently assumed.
Red List Status
Least Concern (LC)
Listed as Least Concern because, although its Extent of Occurrence is less than 5,000km2, it occurs in a well protected military area that is not currently threatened, and its population is not thought to be in decline.
