Southeastern Brazil, more common in Atlantic forest of São Paulo and Rio de Janeiro, but also ocurring further north in Pernambuco (Northeastern Brazil).

Conservation

Least Concern (LC). With a wide distribution in Southeastern Brazil, this species is not particularly threatened. However, with the increasing destruction of the Brazilian Atlantic forest vegetation, it may be already locally endangered in Pernambuco where it has been found only once.
