This species is believed to be entirely restricted to the Cosñipata Valley (1,580-1,700m asl), on the north-eastern slopes of the Cadena de Paucartambo, a frontal range of the Andean Cordillera Oriental in Cusco Department, Peru.
Habitat and Ecology
It can be found in tall forest with some tree ferns and bromeliads and luxuriant undergrowth of mosses and ferns. Except for a single individual that was collected under a rock, all specimens have been recorded calling from low vegetation in cloud forest at night. It is not known from modified habitats. This species breeds by direct development.
It is a rare species.
The major threat is small-scale agriculture (involving both crops and livestock) taking place within the valley.
Part of the range is well protected within Parque Nacional Manu. Further survey work is necessary to determine the species' current population status and whether it is indeed confined to the Cosñipata Valley.
