This species occurs in the Atlantic versant from eastern Honduras to central Panama, and on the Pacific slope from eastern Panama through the Pacific lowlands of Colombia (two known localities in Choco Department) to northwestern Ecuador. It has been recorded below 750m asl (Brian Kubicki pers. comm.).
Habitat and Ecology
A nocturnal, canopy species that inhabits primary humid lowland forest. Specimens have been found in the forest canopy and understorey above a headwater streamlet on a forested ridge. They have been seen at night on leaves and trunks of trees. It generally lives in the canopy, coming down only to breed. It breeds in tree holes and in small pools without fish. Eggs are deposited in the water-filled crevices and cavities of fallen trees; larvae develop in these pools. The same breeding site may be used until it is filled by falling debris (eg. leaves). It has been recorded only from undisturbed forest.
This species is often considered to be a rare species, although more likely it is under-recorded, since it is a canopy species and has a very soft call (Brian Kubicki pers. comm.). Only occasional individuals are seen from time to time.
The major threats are deforestation for agricultural development, illegal crops, logging, and human settlement, and pollution resulting from the spraying of illegal crops. The known localities in Ecuador are facing considerable human pressure. This species occurs at too low densities to be of interest to the international pet trade.
It has been recorded in protected areas in Ecuador but not in Colombia. It has been recorded from several protected areas in Central America.
This species was previously within the genus Agalychnis but has recently been moved to the new genus Cruziohyla (Faivovich, et al., 2005).
