This species is only known from the type locality: 4km south of the junction of the Sonsón-Dorada and Argelia roads, Municipality of Sonsón, Department of Antioquia, in the northern part of the Central Cordillera of the Colombian Andes, at 2,350m asl.
Habitat and Ecology
It has been recorded from primary cloud forest on herbaceous vegetation and fallen leaves, and breeds by direct development.
It is uncommon; two specimens were collected in 1978 and a further four in 1981. Since then, repeated searches of the type locality have not found any individuals, and surveys in the surrounding areas have not recorded this species.
Habitat loss caused by logging and agricultural development (illegal crops) is the major threat at the type locality.
The type locality does not fall within a protected area, and the habitat has been so badly disturbed that it might not even be suitable for protection. Further survey work is required to determine whether or not the species still survives at the type locality; any surviving individuals might need to form the basis for the establishment of an ex-situ population.
