This species can be found in the upper cloud forest at elevations of 2,075-3,000m asl on the western flank of the Andes in the provinces of Pichincha, Imbabura, Carchi, Cotopaxi and Bolívar, Ecuador.
Habitat and Ecology
It seems to be restricted to the upper humid montane forest, and has been found most commonly under stones, logs, and wood chips along road cuts and in pastures by day (Lynch and Duellman 1997). In Cashca Totoras, this species is only found near streams. Reproduction occurs by direct development.
It is recorded as being uncommon in two sites (at Intag and Moran, in 2002), but common in Cashca Totoras (in 2000-2003).
The major threat is habitat destruction and degradation due to livestock farming and wood extraction activities, and the habitat is now severely fragmented.
Its geographic range overlaps several protected areas, including the Reserva Geobotánica Pululahua and the Reserva Ecológica Cotacachi-Cayapas.
