This species is present throughout much of the Amazonian lowlands of Peru, Ecuador, southern Colombia and western Brazil (Acre). It has been recorded from elevations of 200-950m asl.
Habitat and Ecology
This species can be found in primary tropical lowland terra firme forest. The species is usually found in the litter of tropical rainforests, occasionally in open areas. It breeds by direct development and egg deposition occurs in leaf-litter. It is not present in modified habitats.
It is a rarely found species.
Presumably there are no major threats; it is a generally widespread species with large areas of suitable habitat remaining. There is some localized habitat loss to general human activities such as collection of wood, logging, agriculture (crops, livestock etc.), oil exploration and colonization.
In Ecuador, its geographic range overlaps with Reserva Biológica Limoncocha, Parque Nacional Yasuní, and Parque Nacional Sumaco Napo-Galeras. It is present in Guepi Reserve Zone, Peru. It occurs in a number of protected areas in Brazil.
