From the IUCN Red List Species Account:


Range Description

This species occurs in humid lowlands on the Atlantic slope from Costa Rica to east-central Panama and on the Pacific versant in southwestern Costa Rica to west-central Panama. Suggestions that the species occurs in Colombia are incorrect (T. Grant pers. comm.). It has an altitudinal range of 10-865 m asl (Savage 2002).

Habitat and Ecology

It is a terrestrial, diurnal species generally found in the leaf-litter of humid lowland forest; it may be found in secondary forest and plantations. Adults are often encountered along rocky sections of forest streams. Eggs are deposited in leaf-litter, the males transport hatching tadpoles to forest streams where they develop.


It is a very common species, though in certain areas of its range including Guayacan, Costa Rica, it is only seen occasionally (Kubicki 2008). In Costa Rica, the species is very abundant and the sub-populations are stable (G. Chaves pers. comm. 2015). Populations at El Copé, Panama, have experienced severe declines. The species was present before and after the chytridiomycosis epizootic in Panama (Woodhams et al. 2008).

Population Trend


Major Threats

In general habitat loss occurs by the destruction of natural forests due to urbanization, agriculture and logging.
