Range Description

This species is known from Cotia, Ibiúna, Juquitiba, Piedade, Pilar do Sul, Ribeirão Grande, and São Bernardo do Campo Municipalities, Reserva Biológica de Paranapiacaba, Santo André municipality, and Parque Estadual Intervales, in São Paulo State, south-east Brazil. It is likely to occur throughout the Serra de Paranapiacaba.

Habitat and Ecology

This species is found in Atlantic Forest remnants. Individuals are usually found on the forest floor, far from water bodies. Breeding takes place by larval development, with terrestrial larvae. It seems to prefer pristine areas, but is also present in forest fragments (Dixo and Verdade, 2006).


This species is common in suitable habitat, being the second most abundantly collected species in Reserva Biológica do Morro Grande (Dixo and Verdade, 2006).

Population Trend


Major Threats

The Atlantic Forest has been subject to substantial deforestation and fragmentation 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.

Conservation Actions

It is known from Parque Estadual Intervales and Reservas Biológica de Paranapiacaba and Morro Grande.

Red List Status
