From the IUCN Red List Species Account:

Range Description

This species occurs in the upper humid forest at elevations of 1,960-3,400 m asl on the Pacific slopes of the Andes and from 2,590-2,700 m asl on the Amazonian slopes of the Andes in northern Ecuador (Sucumbios, Imbabura, Carchi, Napo, and Pichincha Provinces) and southern Colombia (Nariño and Putumayo Departments).

Habitat and Ecology

This species’ habitat is páramo and upper cloud forest. It is a species with low diurnal activity and extensive nocturnal activity. During the day it occurs under rocks and on logs; at night it is active on low vegetation. It can also be found amidst leaf litter (Mueses-Cisneros 2005). Specimens from the Amazon slopes have been found in clearings in cloud forest (Lynch and Duellman 1980, Lynch and Duellman 1997). It is able to withstand some habitat disturbance. Reproduction is presumed to occur via direct development.

Population

It is abundant in 2000-2003 in all five Ecuadorian provinces where the species has been recorded.

Population Trend

stable

Major Threats

General habitat loss caused by deforestation, agricultural development, and illegal crops are all threats.

Conservation Actions

In Colombia, there are no natural reserve areas in the distribution area of this species. In Ecuador, its geographic range overlaps with Reserva Ecológica Cotacachi-Cayapas.

Red List Status

Least Concern (LC)

Rationale

Listed as Least Concern since, although its Extent of Occurrence is probably less than 20,000 km², it is common and adaptable with a presumed large population, and it is unlikely to be declining to qualify for listing in a more threatened category.
