This species is known only from two localities 60km apart (Domingos Martins and Santa Teresa) in Espírito Santo State in the Atlantic coastal forest region of south-eastern Brazil, at 600-800m asl. It might occur a little more widely.
Habitat and Ecology
It has been found only in secondary forest, and breeds in small, swift, clean mountain brooks. It does not appear to survive outside forest. It lives on vegetation 1-4m above the streams, and the egg clutches are attached to leaves overhanging the streams.
It is a rare species, though there have been some recent records.
The major threats to this species are probably related to habitat loss due to agricultural development (for wood plantations and livestock grazing), and clear-cutting and human settlement.
It is not known from any protected areas, and the establishment of new protected areas is a matter of urgency. Surveys are urgently needed to determine whether or not this species is in decline.
Red List Status
Data Deficient (DD)
Listed as Data Deficient in view of continuing uncertainties as to its extent of occurrence, status and ecological requirements.
This species was previously within the genus Hyla but has recently been moved to the resurrected genus Dendropsophus (Faivovich et al. 2005).
