This species occurs on the Pacific slopes of the Andes in Ecuador (Imbabura and Pichincha Provinces) and extreme southern Colombia (Department of Nariño). It is likely to occur between these two areas, and perhaps more widely. Its known altitudinal range is from 1,460-2,800m asl.
Habitat and Ecology
It is a species of montane cloud forest, also surviving in secondary growth where there is good vegetation cover. It has been found on low vegetation in dense forest at night, sometimes close to streams. Juveniles are active during the day on the forest floor. It breeds by direct development and the eggs are deposited in leaf-litter.
It is common in both undisturbed and secondary habitats.
The major threats are likely to be deforestation for agricultural development, plantations, illegal crops, logging, and human settlement, and pollution resulting from the spraying of illegal crops.
It occurs in the La Planada private reserve in Colombia. In Ecuador, its geographic range overlaps with the Reserva Ecológica Los Illinizas.
This species was redescribed by Lynch (1970).
