Listed as Endangered because its extent of occurrence (EOO) is 69 km2, it occurs in two threat-defined locations, and there is a continuing decline in the extent and quality of its habitat.
|Previously published Red List assessments:|
|Range Description:||This species is known only from a small area in the western slopes of the Cordillera Occidental, at La Planada at 1,200 m asl in the department of Nariño, extreme southern Colombia, and just across the border at Maldonado at 1,410 m asl, in the province of Carchi, extreme northern Ecuador. It may occur more widely. Its extent of occurrence (EOO) is 69 km2.|
Native:Colombia (Colombia (mainland)); Ecuador (Ecuador (mainland))

|Population:||It is a rare species. As of 2016, the species has not been recorded in at least 30 years in either Colombia or Ecuador. The Ecuadorian locality has been well surveyed, but due to civil unrest, the Colombian site has not been sampled since approximately 2005 (Colombia and Ecuador Red List Assessment Workshops July and August 2016).|
|Current Population Trend:||Decreasing|
|Habitat and Ecology:||This species is an inhabitant of cloud forest, and is associated with the spray zones of waterfalls, where it lives on vegetation and rocks. Its ability to adapt to modified habitats is unknown, but it is unlikely to tolerate significant habitat alteration. It is presumed to breed by direct development, but the site of egg deposition is not known.|
|Continuing decline in area, extent and/or quality of habitat:||Yes|
|Movement patterns:||Not a Migrant|
|Use and Trade:||There are no records of this species being utilized.|
|Major Threat(s):||The major threats are likely to be habitat loss and degradation due to agricultural development, plantations, cultivation of illegal crops, logging, and human settlement.|
This species occurs in the La Planada private nature reserve in Colombia.
There is a need for further protection of cloud forest habitat in the region.
Further research into the ecology of this species is required.
