This species is known only from the type locality of Pan de Azúcar, Medellín, Antioquia Department, Colombia, at 1,800 m asl.
Habitat and Ecology
This species was found on vegetation in cloud forests and was thought to be restricted to forest habitat. The habitat at the type locality has been completely transformed and has disappeared due to urbanization (Colombia Red List Assessment Workshop August 2016). It breeds by direct development.
It is only known from three specimens collected in 1983 and has never been recorded since. Surveys in areas near the type locality with suitable habitat have not recorded the species (Colombia Red List Assessment Workshop August 2016). If a population still exists it is thought to have less than 50 individuals.
The habitat at the type locality has been completely destroyed as a result of human settlement.
This species has not been recorded in any protected areas.
Any surviving individuals might need to form the basis for the establishment of an ex-situ population.
Surveys are needed to determine whether the species is extant or occurs in suitable habitat near the type locality.
Red List Status
Critically Endangered (CR)
Listed as Critically Endangered Possibly Extinct since it is only known from three specimens from the type locality and has not been seen since 1983. The type locality has been completely destroyed due to urbanization and surveys in potential suitable habitat in nearby areas have not recorded the species. If extant, it is suspected that the population is less than 50 mature individuals.
