This species is known from the western versant of the Cordillera Occidental, from Antioquia to Valle del Cauca in Colombia. It occurs between 1,700–2,500 m asl. Its extent of occurrence (EOO) is 14,802 km2.
Habitat and Ecology
This species has only been recorded from primary forest, where they are found on vegetation. They are direct developing frogs with the eggs kept in the pouch of the female.
The 2004 assessment described the species as being common, but it is now thought to be an uncommon species. The species has not been recorded since 1997, despite recent surveys searching for it (W. Bolívar pers. comm. August 2016). Due to ongoing decline in the extent and quality of habitat, the population is suspected to be decreasing. If a population still exists it is thought to have less than 50 individuals.
The major threat is habitat loss due to the expansion of agriculture, cattle grazing and logging. Batrachochytrium dendrobatidis has been found in two localities, and while there is currently no direct information confirming that Bd has caused declines in this species (B. Wilmar pers. comm. August 2016), the lack of records since the late 1990s is consistent with the pattern of decline in many other montane amphibian species, and it is therefore reasonable to infer that the disease might be the cause of declines in this species (Colombia Red List Assessment Workshop August 2016).
The range of the species includes Tatamá National Park and Reserva Natural Cerro El Inglés and is near Farallones de Cali National Park.
Further research in population trends, ecology, threats and distribution are recommended for the species.
Red List Status
Critically Endangered (CR)
Listed as Critically Endangered because this once abundant species has not recuperated from a drastic population decline, inferred from the apparent disappearance of most of the population possibly due to chytridiomycosis in the 1990s. If a population still exists it is thought to have less than 50 individuals.
This genus has recently been moved from the family Hylidae (Faivovich et al. 2005).
