This species is known only from between 250 and 600m asl, in the Río Napo drainage in the provinces of Napo, Francisco de Orellana and Sucumbíos, Ecuador. It is expected to occur much more widely, but this has not yet been confirmed.
Habitat and Ecology
This species occurs in the eastern Cordillera Real montane forest and Napo moist forest in the eastern tropical altitudinal zone of Ecuador. Specimens have been found only occasionally, on trees or bushes around 6m above the ground in primary forest. It is a canopy dweller, which is where males call from, and is thought to breed in bromeliads (up to 30m above the ground). It has also been recorded from banana plantations.
The population status of this species is not known, since only a few specimens have been found so far. This is primarily due to it occurring in the high forest canopy, making it very difficult to survey.
The major threats to this species’ habitat are agricultural development (for both crops and livestock), and logging.
Its range includes Parque Nacional Sumaco Napo-Galeras and Parque Nacional Yasuní.
