From the IUCN Red List Species Account:


Range Description

This species occurs in the humid lowlands from southwestern Costa Rica to eastern Panama on the Pacific slope, and on the Atlantic versant in central Panama, to northern Colombia and the middle Magdalena Valley. Its range is expanding in Costa Rica. It ranges from sea level up to 500m asl.

Habitat and Ecology

It is a nocturnal tree frog that inhabits lowland moist and wet forests close to shallow rocky pools, and stream banks. It can survive in secondary forest, but it generally needs good vegetation cover. In Costa Rica, it has been observed in relatively open areas (Federico Bolaños pers. comm.). It is less frequently found in the vegetation overhanging the streams. Benthic tadpoles are found in clear pools and slow-moving water.


It is a common species in Panama and Colombia. In Costa Rica it is rare, despite its expanding range.

Population Trend


Major Threats

The major threats are likely to be deforestation for agricultural development, illegal crops, logging, and human settlement, and pollution resulting from the spraying of illegal crops.

Conservation Actions

It has been recorded from many protected areas.
