From the IUCN Red List Species Account:

 

Range Description

This species is known only from the type locality: Ilha de Alcatrazes, an island off the coast of the state of São Paulo, Brazil. The maximum elevation of the island is no more than 100m asl.

Habitat and Ecology

It occurs in primary and secondary forest, and has also been recorded from degraded forest. The breeding habits are unknown, but it presumably breeds in water by larval development.

Population

The population status of this species is unknown.

Population Trend

Decreasing

Major Threats

Ilha de Alcatrazes was used as a military base in the past, but this is no longer the case. Although there currently is no human settlement on the island, direct disturbance of the species, and degradation of its habitat from touristic activities and fire are ongoing threats.

Conservation Actions

There are no protected areas established on the island. Further survey work is required to determine the biology and population status of this species.

Taxonomic Notes

This species was removed from synonymy (as a subspecies) of Scinax catharinae by Peixoto (1988).
