This species from southeastern Brazil is known from four localities: Santa Teresa (the type locality) in the State of Espírito Santo; Teresopolis and Parati in the State of Rio de Janeiro; and Ubatuba in the State of Sao Paulo State. Its altitudinal range is 200-800m asl.
Habitat and Ecology
It lives in primary and secondary forest, but not in open areas. It is usually found on vegetation near permanent or temporary shallow streams, in which the tadpoles develop.
It is common where it occurs.
The major threats are probably related to habitat loss due to agriculture, clear-cutting, human settlement and fire.
A similar species, Phrynomedusa cf. marginata has recently tested positive for Batrachochytrium dendrobatidis infection (Toledo et al., 2006b).
It has been found in several protected areas.
Red List Status
Least Concern (LC)
Listed as Least Concern in view of its wide distribution, tolerance of a degree of habitat modification, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.
