This species' type locality is near Ollantaytambo in the Urubamba Valley, Cusco Region, Peru, from 2,700–2,800 m asl. There is a great deal of taxonomic uncertainty around the identity of some specimens assigned to this species. Specimens assigned to this species from the buffer zone of Manu National Park are in fact Gastrotheca nebulanastes (A. Catenazzi pers. comm. April 2017) and only the subpopulation situated in the vicinity of the type locality is treated in this assessment, which results in an EOO of 709 km2. All individuals are considered to occur at one to three locations.
Habitat and Ecology
It is known to use bromeliads as microhabitats (Duellman and Fritts 1972); all specimens have been found in small bromeliads growing on cliffs. The eggs undergo direct development in the females pouch (Duellman and Trueb 2015).
It appears to be rare. Surveys at the type locality recorded the species as recently as 2014 (L. Mamani Ccasa pers. comm. April 2017).
It is threatened by agricultural practices that clear land by burning for crop planting and livestock grazing. In addition, it occurs near archaeological sites that receive many visitors and this may put pressure on the species' habitat at those sites.
The species has not been reported from any protected areas, but it might occur in the Machu Picchu Historic Sanctuary. The species is listed as Critically Endangered (CR) in Peru and has legal protection provided by the Categorization in Endangered Species of Wild Fauna (Decreto Supremo Nº004-2014-MINAGRI), which bans all hunting, capture, possession, transport or export of the species for commercial purposes.
This species would benefit from improved habitat protection at sites where it is known to occur.
More information is needed on this species' distribution, population status, ecology, and taxonomy.
Red List Status
Data Deficient (DD)
Listed as Endangered in light of its restricted range – estimated extent of occurrence (EOO) is 709 km2 – and ongoing decline in the quality and extent of its habitat, which divides its population into three or fewer threat-defined locations.
