Listed as Critically Endangered because its Extent of Occurrence is less than 100 km2, its distribution is severely fragmented, and there is continuing decline in the extent and quality of its habitat.
This species is known only from the vicinity of the type locality in the eastern Andes west of the Apurimac River, and from Cordillera Vilcabamba, Departamento Ayacucho, Peru, between 2,460 and 2,650m asl. It is believed to be a genuinely restricted-range species.
It is not known to occur in any protected areas, making habitat protection and maintenance a priority. The species is, in general, quite poorly known, and further research is needed into its biology and population status.
