This species is known only from the region of the type locality in cloud forest on the western slope of the Andes in extreme southern Colombia. It is presumed to extend into adjacent Ecuador but has not yet been recorded there. It ranges from 1,700-2,020m asl.
Habitat and Ecology
It is nocturnal, and is usually found on medium to high vegetation along side streams inside primary forest. Breeding is by direct development.
It is not a common species.
There are no major threats to the habitat at the type locality at present, but there is pressure from local people to convert the current protected area to land for agriculture and cattle farming.
The only known locality is within La Planada Natural Reserve. Continued management and maintenance of this protected area is essential to ensure the long-term survival of this species, particularly given its dependence upon good forest. Further survey work is needed to establish the current population status of this species, and to determine if it occurs outside the vicinity of the type locality.
Red List Status
Listed as Endangered because its Extent of Occurrence is less than 5,000 km2, all individuals are in fewer than five locations, and there is continuing decline in the extent and quality of its habitat on the Western Cordillera of the Colombian Andes.
