|Taxonomic Notes:||It is considered as a species complex (W. Bolívar pers comm. 2016).|

Listed as Least Concern because although the distribution and extent of occurrence (EOO) is somewhat restricted (EOO of 16,563 km2), the population trend appears to be stable, threats are mostly localized, and it is found in several protected areas.
|Previously published Red List assessments:|
|Range Description:||This species is known from Chocó, Antioquia, Cauca, Valle de Cauca and Risaralda Departments, on the western flank of the western Andes, Colombia. Its altitudinal range is 1,280–2,000 m Asl (Bernal and Lynch 2008).|

|Population:||Formerly common, it is now considered to be an uncommon species and therefore it is inferred that the population is decreasing. During 2008–2009, visual encounter surveys in Reserva Forestal Protectora del Río Bitaco, Valle del Cauca, detected 35 individuals in riparian forest habitats over 35 person-hours (Méndez-Narváez and Bolívar-G 2016). The population is not considered severely fragmented.|
|Current Population Trend:||Decreasing|
|Habitat and Ecology:||It occurs on vegetation next to streams in primary sub-Andean forests. Eggs are laid on the upper surface of leaves and when hatched the larvae fall into the water below where they then develop further.|
|Movement patterns:||Not a Migrant|
|Use and Trade:||There are no records of this species being utilized.|
|Major Threat(s):||Localized threats include habitat fragmentation and loss due to logging, agriculture, livestock, illegal mining activities, and pollution of water sources. Batrachochytrium dendrobatidis has been reported in the range of the species, but there is no evidence on how it may be affected (W. Bolívar pers. comm. August 2016).|
This species occurs in Parque Nacional Natural Farallones de Cali, Parque Nacional Natural Tatamá, Reserva Forestal Protectora del Río Bitaco, and Parque Nacional de Las Orquídeas.
More information is needed on this species' distribution, population status, natural history, and threats. Studies are needed to obtain information on its susceptibility to threatening processes, including chytrid fungus. Taxonomic work is needed to determine if this form is a complex of more than one species.
