From the IUCN Red List Species Account:


Range Description

This species is only known from lowland and intermediate elevations between 200 and 450m asl, of the Río Napo drainage in the provinces of Napo, Francisco de Orellana and Sucumbíos, in Ecuador. It is also known from the Iquitos area in the Loreto department in Peru. Further work is likely to show that this species occurs much more widely.

Habitat and Ecology

In Ecuador it occurs in the Napo moist forest in the Eastern tropical Altitudinal Zone. It is an inhabitant of primary forest. A canopy dweller, it breeds by larval development in bromeliads, usually very high up in trees (up to 15m above the ground). It does not adapt well to anthropogenic disturbance.


The population status of this species is not known. This is primarily due to the species occurring in the high forest canopy, so it is very difficult to determine its population status.

Population Trend


Major Threats

Agriculture, both crops and livestock, as well as logging are major threats to the species’ habitat.

Conservation Actions

Its distribution range includes Parque Nacional Yasuni in Ecuador, and it might also occur in protected areas in Peru.
