Range Description

This species is known from the Umasbamba Valley, near Abra de Málaga, and Canchayoc, District of Huayopata, Province of La Convención, Department of Cusco, Peru. Further individuals were recorded in upper reaches of the adjacent Ocobamba Valley during surveys in 2013 (A. Ttito pers. comm. April 2017). It occurs between 3,555–3,950 m asl (Chaparro et al. 2007). In the previous assessment, this species' distribution was incorrectly mapped 15–25 km east of the known localities, largely extending into to Calca Province from which there are no records. Based on the current range map, its EOO is 149 km2.

Habitat and Ecology

This terrestrial species inhabits the transitional zone from cloud forest to the humid grassy puna. Individuals were found in two kinds of habitats: humid, grassy puna (between 3,700–3,950 m asl) and the adjacent humid forest (between 3,555–3,700 m asl). These frogs can be found during both rainy and dry seasons, under stones along roads, within bushes and grass, and under moss (Chaparro et al. 2007). Males call from bushes during the day in April. The female holotype, collected in April, contained convoluted oviducts. It possibly reproduces during this month, in the rainy season (J.C. Chaparro pers. comm. 2008). The species is thought to reproduce by direct development. Other amphibians found in sympatry were Nannophryne corynetes, Gastrotheca excubitor, Pleurodema marmoratum and Pristimantis rhabdolaemus (Chaparro et al. 2007).


This species is infrequently encountered. Four surveys carried out in April, August and December 2006 and February 2007, comprised of 10 transects of 100 m each, detected six specimens in April and four in August (Chaparro et al. 2007). However, surveys in 2008 (A. Catenazzi pers. comm. April 2017), 2013 and Feburary 2017 (A. Ttito and F.P. Condori pers. comm. April 2017) were able to record the species.

Population Trend


Major Threats

A road was constructed at the type locality increasing human activity in the area (Chaparro et al. 2007), but at the same time a private conservation area was created in the same area (A. Catenazzi pers. comm. April 2017). In March 2008, an anuran at Abra Málaga was found to be infected with the pathogenic fungus Batrachochytrium dendrobatidis (Lehr and Catenazzi 2010)The pathogen has yet to be reported from this species, however it has been found to infect individuals of the related species, Bryophryne cophites (Catenazzi et al. 2011). However, direct developing frogs such as this species are not likely to be affected by chytrid (A. Catenazzi pers. comm. April 2017).

Conservation Actions

Conservation Actions
It occurs within Abra Málaga Private Conservation Area, a private reserve between Málaga Chico and Río San Luis, established in 2007.

Research Needed
More information is needed on this species' distribution, population status, and natural history.

Red List Status

Endangered (EN)


Listed as Least Concern because, although it has a restricted range —its estimated extent of occurrence (EOO) is 149 km2—there are no ongoing threats at known sites, it is protected by the Abra Málaga Private Conservation Area, and it is regularly encountered when surveys are conducted.

Taxonomic Notes

Bryophryne bustamantei can be distinguished from other similar species by a combination of morphological features and colour patterns (Chaparro et al. 2007).
