Frogs of the genus Eleutherodactylus (Leptodactylidae) in the cordillera occidental in Peru with descriptions of three new species. Scientific Papers, Natural History Museum, The University of Kansas 39: 1-13.1094-0782https://hdl.handle.net/1808/4261Three new species of Eleutherodactylus are described from the Río Zaña Valley in the Pacific versant of the Cordillera Occidental in the Departamento de Cajamarca, Peru. One of the species is a member of the Eleutherodactylus conspicillatus Group, and two are members of the Eleutherodactylus unistrigatus Group. We recognize 15 species of Eleutherodactylus in the Cordillera Occidental; 10 of these species are reported for the first time from the Cordillera Occidental. Four of these species are shared with the Cordillera Occidental in Ecuador, and five are shared with the Cordillera de Huancabamba in northern Peru.en-USThis work is licensed under a Creative Commons Attribution-NonCommercial-ShareAlike 4.0 International License.http://creativecommons.org/licenses/by-nc-sa/4.0/Cordillera OccidentalEleutherodactylusPeruTaxonomyBiogeographyLeptodactylidaeArticleopenAccess
