This species is known from the Serra dos Itatins, in São Paulo State, Brazil, from 50-700m asl.
Habitat and Ecology
This diurnal species inhabits small streams in primary and secondary forest. Males are territorial and call from rocks along streams. Oviposition takes place in submerged nests, previously excavated by the male in sand and gravel.
It is very common in primary forest, but is less common in secondary forest.
Habitat loss due to the felling of palm trees is a threat to its habitat, and is also occurring within the protected area in which the species is found. Infrastructure development for human settlement and disturbance by tourists are also threats.
This species has recently tested positive for Batrachochytrium dendrobatidis infection (Toledo et al., 2006b).
The range of this species includes the Estação Ecológica da Juréia-Itatins.
Red List Status
Data Deficient (DD)
Listed as Data Deficient since it has only recently been described, and there is still very little known about its extent of occurrence, area of occupancy, status and ecological requirements.
