This species is known only from Cosñipata (at 1,700m asl), in Cuzco Department in the Andes in southern Peru.
Habitat and Ecology
Its habitat is tall primary and secondary Amazonian cloud forest with some tree ferns and bromeliads and luxuriant undergrowth of mosses and ferns. Individuals have been recorded perched on and calling from the upper sides of ferns along a dripping cliff at night (this species is often close to streams and waterfalls). Eggs are deposited on leaves and the larvae develop in streams.
It is an uncommon species.
There are no major threats to this species. A road passes through the park in which it is found, but this is not believed to be a significant threat.
It occurs entirely within Parque Nacional Manu. Further research is needed concerning the potential impacts of localized climate change and possible infection with the chytrid fungus.
