From the IUCN Red List Species Account:

 

Range Description

This species is known from the Pacific slope of the Cordillera Occidental, in the departments of Valle del Cauca and Choco, in Colombia, from 1,700-2,250m asl.

Habitat and Ecology

This is a nocturnal species found on medium to high level vegetation in primary cloud forest. Breeding is by direct development.

Population

It is uncommon.

Population Trend

stable

Major Threats

There are currently no major threats to the species' habitat although there are plans to build a road across the Serrania de los Paraguas. This will become a major threat if the plans go ahead, and would provide access for the expansion of agricultural activities and logging.

Conservation Actions

Most of the range of this species is within the mountains of Los Paraguas, which forms a natural unit of the high Andean ecosystem. At present there is an ongoing effort to transform this area into a wildlife reserve. Other populations are inside Parque Nacional Natural Farallones de Cali. Conservation of the species' habitat is essential for its long-term survival since it is restricted to primary forest.

Red List Status

Near Threatened (NT)

Rationale

Listed as Near Threatened because although the species appears not to be in decline, its Extent of Occurrence is less than 5000 km2, thus making the species close to qualifying for Vulnerable.

Taxonomic Notes

The form is the sister species of Pristimantis appendiculatus according to Lynch and Ruíz-Carranza (1996).
