Range Description

Melanophryne barbatula is only known from Yanachaga-Chemillen National Park, at approximately 2500 masl, District of Oxapampa, Province of Oxapampa, Department of Pasco, Peru. Yanachaga-Chemillén is in the valley of the Río Palcazu in the Amazon Basin of central Peru (Lehr and Trueb, 2007).

Habitat and Ecology

Yanachaga-Chemillen National Park is 122 000 ha in area and consists primarily of the Cordillera de Yanachaga, reaching an elevation of 3643 masl. On the eastern side of the park, the Cordillera de Yanachaga descends gradually into the valley of the Río Palcazu. On the western flank, the Cordillera de Santa Barbara reaches an elevation of 3400 m and is
separated from the Cordillera de Yanachaga by the deep Huancabamba Canyon (Lehr and Trueb, 2007).

The species is found within forested areas (E. Lehr, pers. comm. 2008). One female contained 22 pigmented eggs with an average diameter of 1.6 ± 0.09 mm (n = 10). One stomach content revealed a diet consisting of arthropods belonging to Blattelidae, Carabidae, Cryptorhynchinae, Galumnidae, Oribatidae and Formicidae, suggesting that the species is a leaf litter inhabitant (Lehr and Trueb, 2007). Although the reproduction mode is unknown, it is possible that the species may use terrestrial bromeliads like M. carpish (E. Lehr, pers. comm. 2008).

Population

The current populations size for this species is unknown (E. Lehr, pers. comm. 2008).

Population Trend

Unknown

Major Threats

Deforestation was observed to occur in the region (E. Lehr, pers. comm. 2008).

Conservation Actions

The species occurs within a protected area, Yanachaga-Chemillen National Park (Lehr and Trueb, 2007).

Taxonomic Notes

Melanophryne barbatula is diagnosed by a combination of morphological characters (Lehr and Trueb, 2007).
