Range Description

This species is present in eastern Suriname, central Guyana, French Guiana and Amazonian Colombia, Ecuador, Peru, Bolivia, and Brazil. Lescure and Marty (2001) gave a record for Peru. McDiarmid and Paolillo (1988) gave the first and only record of this species in Venezuela: Rio Baria, base del Cerro Neblina in Amazonas State; no further Venezuelan samples are known. Its altitudinal range is 0-450m asl.

Habitat and Ecology

This frog inhabits the canopy of tropical primary rainforest, where they breed in tree cavities and may seldom, if ever, descend to the ground (Rodríguez and Duellman, 1994). At Yasuní National Park, Ecuador, this species has been found in open area, floodable forest, and in Terra firme forest on branches of trees (Ron, 2001). It reproduces in tree cavities and it is characterized by loud vocalization.


Rarely recorded, probably because of its arboreal habits.

Population Trend


Major Threats

Local populations are no doubt impacted by forest conversion, clear cutting, selective logging, and human settlement. However, overall this species is not significantly threatened.

Conservation Actions

Conservation units are present within its range. Venezuelan population protected in Sierra de la Neblina National Park, Amazonas state. In Ecuador, its geographic range overlaps with Parque Nacional Yasuní.

Taxonomic Notes

This species was previously within the genus Phrynohyas which was recently synonymized with Trachycephalus (Faivovich, et al., 2005).
