This species is known from the Amazonian slopes of the eastern Andean Cordillera (Cordillera de Matanga to the Abra de Zamora) in southern Ecuador from 2,195-2,850m asl. It has also been reported from 3,400m asl at Río Mazan, Azuay. It is recorded from six localities.
Habitat and Ecology
It inhabits páramo grassland, sub-páramo shrubland and cloud forests (Lynch and Duellman 1980). Breeding is by direct development.
There is very little information available on the current population status of this species. Four individuals were collected in 1985, but there appear to be no subsequent records, though this is probably due to a lack of survey work within its range.
The habitat of this species is under threat from agricultural activities and dam construction.
Its range overlaps Parque Nacional Sangay, and also Parque Nacional Cajas.
