From the IUCN Red List Species Account:


Range Description

This species occurs in the mountainous parts of southern and southeastern Brazil (from southern Minas Gerais south to northern Rio Grande do Sul), west to east-central Misiones Province, Argentina. Its altitudinal range is 400-1,700m asl.

Habitat and Ecology

This is an arboreal frog found in the canopy of primary forest. It is an explosive breeder, spawning in permanent still waterbodies in the forest. Probably not tolerant of much habitat disturbance.


This species is not well known and is probably a rare species, although some very large populations have been found breeding in the northern part of its range. The southern population (which is probably a different species) seems to be much rarer. It is probably easily overlooked when not breeding.

Population Trend


Major Threats

The major threats are probably related to habitat loss due to agriculture, livestock grazing, wood plantations, logging and human settlement.

Conservation Actions

It is not known from any protected areas in Brazil. Occurs in a small private reserve in Argentina.

Red List Status

Least Concern (LC)


Listed as Least Concern in view of its wide distribution, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.

Taxonomic Notes

Two species are included under this name (A. Kwet pers. comm.). This species was previously within the genus Phrynohyas which was recently synonymized with Trachycephalus (Faivovich, et al., 2005).
