Wild Division of Herpetology, Museum bf Natural History, and Department of Systematics and Ecology, The University of Kansas, Laurence, Kansas 66045-2454, USA ABSTRACT The anuran fauna of the Cordillera de Huancabamba in northern Peru consists of 21 species, 10 of which are endemic. Most of the species and all of the endemics occur in the humid montane forest on the western slope and summit of the cordillera, where most of the species are eleutherodactylines that have direct development of terrestrial eggs. Only five species occur in the dry tropical forest at elevations below 1700 m in the cordillera. Seven groups are recognized based on ecological similarity. Eight species reach the southern limits of their distributions in the cordillera, and one species reaches its northern limit. Centrolene buckleyi, Eleutherodactylus cryptomelas, and E. phoxocephalus are reported for the first time from Peru. Eleutherodactylus ceuthospilus, E. rhodoplichus, E. sternothylax, and E. wiensi are described as new species. Colostethus paradoxus and Phyllobates anthonyi are placed in the synonymy of Epipedobates tricolor. The tadpole of Colostethus sylvaticus is described. Key words: Peru. Andes, Biogeography. Ecological distribution. Anura, New species. RESUMEN La fauna de anuros de la Cordillera de Huancabamba en el norte del Peru consiste de 21 especies, 10 de las cuales son endemicas.
