This species occurs in the lowlands of south-western Costa Rica, adjacent south-western Panama, and possibly in south-eastern Costa Rica, from 20-100m asl.
Habitat and Ecology
A diurnal, terrestrial species most often found in relatively undisturbed humid lowland forest, but also recorded from secondary forest and plantations. Eggs are deposited on the forest floor and the female transports the tadpoles to bromeliads to complete metamorphosis.
It is common in Costa Rica.
The major threat is habitat loss due to agriculture, selective logging, and human settlement. The current level of offtake of specimens for the international trade is unknown.
It is present in several protected areas, including Parque Nacional Corcovado.
