Bryophryne bustamantei is known only from the Umasbamba Valley, near Abra de Málaga, and Canchayoc, District of Huayopata, Province of La Convención, Department of Cusco, Peru, between 3,555–3,950 masl (Chaparro et al. 2007).
Habitat and Ecology
This species inhabits the transitional zone from cloud forest to puna. Individuals were found in two kinds of habitats: humid, grassy puna (between 3,700–3,950 m) and the adjacent humid forest (between 3,555–3,700 m). These frogs can be found during both rainy and dry seasons, under stones along roads, within bushes and grass, and under moss. Males call from bushes during the day in April. The female holotype, collected in April, contained convoluted oviducts. Other amphibians found in sympatry were Nannophryne corynetes, Gastrotheca excubitor, Pleurodema marmoratum, and Pristimantis rhabdolaemus (Chaparro et al. 2007).
The species is thought to have direct development. It may possibly reproduce during the rainy season, e.g., April (J.C. Chaparro, pers. comm. 2008).
This is considered to be a rare species (Chaparro et al. 2007).
The type locality of B. bustamantei is being severely affected by the construction of the Cusco-Quillabamba road and the increasing human activity in the area (Chaparro et al. 2007). Given the restricted distribution of the species and its rarity, Chaparro et al. (2007) proposed to include it as “Endangered” in the Peruvian official list of threatened species and in the IUCN Red List.
No conservation measures are currently known for this species.
Bryophryne bustamantei can be distinguished from other similar species by a combination of morphological features and colour patterns (Chaparro et al., 2007).
