Listed as Critically Endangered because it is known only from the type locality and it has not recuperated from the extreme decline probably caused by chytridiomycosis. It has not been recorded since 1997 despite recent surveys at the site. Therefore the population size is estimated to be probably no more than 50 individuals.

Geographic Range [top]

Range Description:This species is known only from the base of Cerro Ingles, near Vereda Las Amarillas, Município El Cairo, in Valle del Cauca Department, Colombia, at 2,160 m asl. Even though every stream within 5 km of the type locality has been sampled, the species has not been recorded, suggesting that it has a very restricted range (W. Bolívar and P. Gutiérrez pers. comm. August 2016). Its extent of occurrence (EOO) is 51 km2.

Population [top]

Population:It is a rare species and the total population is suspected to be fewer than 50 mature individuals. The last known record was in 1997 (Lynch and Grant 1998) despite recent surveys to locate the species (Colombia Amphibian Assessment Workshop 2016).
Current Population Trend:Unknown
Additional data:
Number of mature individuals:1-49
Population severely fragmented:No

Threats [top]

Major Threat(s): The species suffered a drastic population decline at the end of the decade of 1990, but there is no information on whether chytridiomycosis was the cause, however Bd has been detected in the area (W. Bolívar pers. comm. August 2016).
