This species occurs on the Amazonian slopes of the Andes in Río Salado, Río Azuelo and 16km from Santa Rosa in Napo and Sucumbíos Provinces, Ecuador, at 1,300-1,740m asl.
Habitat and Ecology
It is found near streams in cloud forest, and has been recorded over 3m above the ground. Eggs are presumably laid on vegetation, with the larvae developing in water.
First collected in 1971, this species was last recorded in 1977. Several trips to known localities where the species occurs have not turned up any individuals (e.g. Bustamante 2002); however, the area of available habitat in the vicinity of the type locality is large, and the sampling effort has probably been insufficient.
The main threat to the species is habitat loss and degradation mainly due to smallholder farming and livestock ranching. It is possible that it may also have been affected by chytridiomycosis.
It probably occurs in the Reserva Ecológica Cayambe-Coca. Further survey work is needed to determine the current population status of this species.
