This species can be found in much of the upper Amazonian region of Ecuador (including the Río Santiago Valley), throughout Peru (Departamentos San Martin; Loreto; Ucayali; Huánuco; Madre de Dios) and wide-ranging in western Brazil (Acre State). It is a lowland species.
Habitat and Ecology
A forest inhabitant, most individuals have been observed on bushes and branches of trees at night (Duellman and Wiens, 1993), although, at Santa Cecilia, Ecuador, specimens have been found in primary forest, secondary forest, forest edge, banana grove, and clearing habitats; individuals were on the ground and on vegetation (Duellman, 1978). Temporary pools are used as breeding habitats.
It is not uncommon.
There are no major threats; it is a widespread species with large areas of suitable habitat remaining. There is some localized habitat loss to clear cutting, fire and smallholder farming, but it is a reasonably adaptable species, and it might not be significantly affected by the alteration of its habitat.
In Peru, it might be present in Gueppi, Santiago Comaina and Allpahuayo Mishana Reserved Zones, Pacaya Samiria National Park, Biabo Cordillera Azul Reserved Zone, Alto Purus Reserved Zone and Parque Nacional Manu. In Ecuador it is found in Yasuni National Park; Limoncocha Reserva Biológica and Reserva de Produccion Faunistica Gyabeuo.
