From the IUCN Red List Species Account:


Range Description

This species is known only from the type locality: Cordillera de Carpish, at 2,920 m asl, in the Province of Huánuco, an outlier of the Cordillera Oriental of the Peruvian Andes (Duellman et al. 2004, Duellman and Trueb 2015). It is not known whether or not it occurs more widely.

Habitat and Ecology

This nocturnal frog inhabits cloud forest and use bromeliads as diurnal refuges. Frogs have also been found under leaf litter, under logs and in trees. Eggs undergo direct development inside paired lateral brood pouches of the female and hatch as froglets (Duellman et al. 2004, Duellman and Trueb 2015). One female has been found with six eggs measuring six mm (Duellman et al. 2004).


It is known from only two specimens and there have not been additional surveys since the species description (E. Lehr pers. comm. December 2017). Due to ongoing decline in the extent and quality of habitat, the population is suspected to be decreasing.

Population Trend


Major Threats

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.

Conservation Actions

Conservation Actions
This species is not known to occur in any protected areas. It 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. 

Conservation Needed
Habitat protection and management an urgently needed conservation action. 

Research Needed
Addressing the lack of data is the first step towards ensuring the species' long-term persistence. Further survey work is needed to determine if it occurs outside of the type locality, and more information is needed on this species' population status, natural history and threats.

Red List Status

Critically Endangered (CR)


Listed as Data Deficient in view of the absence of recent information on its extent of occurrence, population status and ecological requirements.
