This species is known only from the vicinity of Santa Teresa and Domingos Martins, in the state of Espírito Santo in south-eastern Brazil, at 650-700m asl.
Habitat and Ecology
This species lives in forest, where it was found on vegetation near streams. It apparently breeds in streams, and hides in bromeliads.
Only a few specimens are known. It has not been found in Santa Teresa since its initial discovery, despite searching, and so it is probably rare there, and only a few specimens are known from Domingos Martins.
There is no direct information on the threats to this species, but in the vicinity of the type locality it is potentially at risk from expanding agriculture, wood plantations, and human settlements, as well as from the collection of bromeliads. The lack of recent records, despite searching, gives cause for concern, given the decline of stream-breeding frogs in other parts of the wet tropics. Declines that have taken place in suitable habitat could be the result of other threats such as climate change or disease (possibly chytridiomycosis).
In view of the lack of recent records and the decline of stream-breeding frogs in other parts of the wet tropics, it is an urgent priority to carry out surveys for this species.
Red List Status
Data Deficient (DD)
Listed as Data Deficient in view of the absence of recent information on its extent of occurrence, status and ecological requirements.
