This species is known from lowland forest in western Brazil, southeastern Colombia, eastern Ecuador and eastern Peru (all Loreto and one record in Ucayali). Its altitudinal range is between 100-500m asl.
Habitat and Ecology
This species occurs in primary forest, where it is most commonly seen on the ground, logs, or tree roots along small streams at night (Rodríguez and Duellman, 1994). The microhabitat is very moist and the forest floor is heavily littered with wet dead leaves. It occurs in areas of flooding forest with close canopy and wide leaves. It also occurs in the forests edges, near small streams secondary and modified forest. It breeds by direct development, leaf-litter Ovid position.
It is common in Peru, Ecuador and Colombia; it is uncommon in Brazil.
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 collection of wood, logging, agriculture (crops, livestock etc.), oil exploration and colonization.
The range of this species in Peru overlaps with some areas proposed as Priority by Conservation of Biodiversity (Rodriguez, 1996). In Ecuador, its geographic range overlaps with Parque Nacional Yasuní and Cuyabeno Reserva. It is present in at least three Colombian protected areas. In Brazil it has been recorded in Parque Nacional da Serra do Divisor and Reserva Extrativista do Alto Juruá, Acre State.
