This species is known from the eastern lowlands of Ecuador, between 250 and 350m asl. It is very poorly known, and is probably more widespread, but this requires confirmation.
Habitat and Ecology
It is an inhabitant of moist Napo forests in the tropical eastern altitudinal zone. It has been recorded only from primary forest, and does not adapt well to anthropogenic disturbance. It is an arboreal species, found up to 30m above ground at the base of bromeliads. Two specimens were found on the ground immediately after large trees had been felled.
There is very little information known about its population status, but this is probably because it is a canopy species that is very hard to detect.
Agricultural development, for both crops and livestock, as well as logging, are major threats to this species’ habitat.
Its range includes Parque Nacional Yasuní.
