This species is only known from the region of the type locality, 8 km east of Sonsón in the Cordillera Central, in the department of Antioquia, Colombia, at 2,780 m Asl. Its EOO is 10 km2.
Habitat and Ecology
The species was recorded on wet rocks very close to the surface of the stream in primary forest. The habitat at the type locality has been completely degraded (G. Gonzalez Duran pers. comm. 2016). Its breeding ecology is unknown.
This species is only known from three specimens. Since its first description, it has not been seen and at least a dozen surveys in the type locality have failed to record it. Recent surveys (2014–2015) in the area of the type locality also failed to record the species (C. Marin pers. comm. August 2016). Due to ongoing decline in the extent and quality of habitat, the population is suspected to be decreasing.
In the past, habitat at the type locality was degraded by guerrilla activities and smallholder farming. However civil unrest has now ceased and is no longer a threat, but agriculture continues to be the main threat to this species (Colombia Red List Assessment Workshop August 2016).
This species has not been recorded in any protected areas.
If the species still survives, restoration and protection of its habitat will be necessary for its survival.
Further survey work is needed to confirm whether or not the species still survives at the type locality or if it occurs outside the vicinity of the type locality.
Red List Status
Critically Endangered (CR)
Listed as Critically Endangered because its extent of occurrence (EOO) is 10 km2, it occurs in one threat-defined location, and there is ongoing decline in the extent and quality of habitat.
