This species is known only from a few sites on the southern end of the Cordillera Azul, east of the Río Huallaga Valley. It has been recorded from the Departments of Huánuco and Pasco, and it is probable that it could occur in Junín given the record so close to the border (E. Lehr pers. comm. April 2017). The range is not completely known and it may occur more widely than current records suggest. It is known from elevations of 2,500–3,090 m asl, its extent of occurrence (EOO) is 3,994 km2, and all individuals are considered to occur in five threat-defined locations.
Habitat and Ecology
This species inhabits humid subpáramo and humid montane forest; it is sometimes present near villages and can be found in pastures with trees. Known specimens have been collected by local residences who claimed that the frogs were found in trees (Duellman et al. 2001). Indirect evidence indicates this species produces tadpoles which complete their development in ponds, but tadpoles in this species are unknown (Duellmann and Trueb 2015). A female was found with 82 eggs in her brood pouch, each with a diameter of about 5.3 mm; the number and size of the eggs indicates that eggs of this species hatch as tadpoles (Duellman et al. 2001).
It is uncommon. Due to ongoing decline in the extent and quality of habitat, the population is suspected to be decreasing.
The Cordillera de Carpish is not protected under Peruvian law, making it susceptible to deforestation for agriculture and timber extraction. The main threat is habitat destruction as a result of agricultural activities, primarily from potato farming and livestock ranching, and firewood collection.
It is not known to occur in any protected areas. It is listed as Endangered (EN) 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.
Some form of habitat protection is needed to ensure the maintenance of some cloud forest within the range of this species.
More information is needed on this species' distribution, population status, natural history, and threats. Survey work is required to determine whether this species might occur between known sites.
Red List Status
Listed as Endangered because its extent of occurrence (EOO) is 3,994 km2, it occurs in five threat-defined locations, and there is continuing decline in the extent and quality of its habitat along the Cordillera Azul in Peru.
