This species occurs disjunctively in Amazonian Ecuador and northeastern Peru. Further field sampling is expected to identify new localities. It probably occurs more widely than current records suggest, especially in areas between known sites. Its altitudinal range is 200-1,200m asl.
Habitat and Ecology
Its habitat is primary and secondary lowland tropical rainforest, often close to bamboo habitats. At Yasuní National Park, Ecuador, this nocturnal species has been collected in floodable forests (Ron, 2001). Breeding takes place in bamboo and tree holes, tadpoles are raised by the female on unfertilised eggs. It is not present in disturbed areas.
It is not locally common.
There are no major threats; it is a relatively 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.).
In Ecuador Its distribution range overlaps with Parque Nacional Yasuni. It is not present in any Peruvian protected areas.
