This species is known from the Amazon basin of southern Ecuador, Amazonian Bolivia, and eastern Peru. The presence of this species in Brazil requires further investigation. It is found in lowlands and recorded as high as 1,700m asl by Duellman and Pramuk, (1999).
Habitat and Ecology
high-elevation, premontane and lowland primary forest (including swamp forest) with close canopy and wide leaves. It is usually observed perched on leaves of trees and bushes at night in swamp forest. It has been found in rotten logs during the day. It breeds by direct development and the egg deposition site is not known. In Ecuador the species has been found in secondary forest and areas slightly disturbed by agriculture.
It is not an uncommon species.
Presumably there are no major threats. It is a widespread species with large areas of suitable habitat remaining. There is some localized habitat loss to general human activities such as agriculture (crops, livestock etc.). For Ecuador, climate change has been suggested as a threat to this species.
In Peru, the range of this species overlaps with Parque Nacional Manu and Tambopata-Candamo National Reserve (Madre de Dios). In Ecuador, its geographic range overlaps with Parque Nacional Sumaco Napo-Galereas, Reserva Ecológica Antisana and Parque Nacional Llanganates.
