This species is known from two localities in Peru: Cosñipata (Cusco Department, at 1,700m asl) in the southern montane forest and Perene Valley (Pasco Department, at 1,200m asl) in the central montane forest. It is believed to occur in suitable intervening habitat.
Habitat and Ecology
Its habitat is montane primary and secondary tropical forest, close to streams. Individuals have been recorded calling at night from the upper sides of leaves of herbaceous plants adjacent to a small stream. It is not present in degraded areas. Eggs are deposited on leaves, and larvae develop in streams.
It is an uncommon species.
In the Perene Valley it is threatened by agriculture (coffee, tea and coca cultivation) and human settlement.
It is present in Parque Nacional Manu. Further research into the distribution of this species is required as well as into the potential impacts of localized climate change and possible infection with the chytrid fungus.
