This species occurs on the Caribbean and Pacific slopes of the mountains of Costa Rica, at elevations of 500-1,580m asl.
Habitat and Ecology
It lives in premontane wet forest and rainforest. A nocturnal stream breeder, males call throughout the year but are most active from August to December. The species sometimes aggregates around small, shallow streams or seeps draining into streams. Tadpoles are found in quiet pools.
It is regularly encountered in suitable habitat throughout its range. This species persists in good numbers in areas known to be infected with chytridiomycosis (Gerardo Chaves pers. comm. 2007).
Threats to this species include deforestation, stream alteration, and pollution, but populations are generally stable.
Its range includes several national parks, such as Braulio Carrillo, and other protected areas.
