ESTADO ACTUAL Y RELACIÓN NOMENCLATURAL DE LOS MAMÍFEROS TERRESTRES DE MÉXICO.

Taking into account the methodological advancements of the last eight years, the updating of the list to subspecific level of the land native mammals of México (Class Mammalia) is been proposed, including nomenclatural changes that have taken place after 1996. The taxonomic changes, which are included, correspond to suggestion of new classification system, one above the specific level and another for the Order Chiroptera; description of new species; changes of taxonomic status of subgenera, genera, subfamilies, and families; sequence of the different orders into the classification system; separation of the components at generic and specific levels, revalidation of the species and subspecies names; incorporation of the names of species and subspecies into the synonym of others; and, correction of the nomenclature of others. The taxonomic categories mentioned in this paper belong to 12 orders, 34 families, 165 genera (13 are endemics), and 475 species (169 are endemics), 204 are monotypic and, 271 are polytypic species with 951 subspecies, 26 species exclusive to islands The information presented herein correspond only to the land native mammals of México, but the mention of two aquatic genus (Enhydra and Lontra) is made, and are excluded the components of the orders Cetacea, Pinnipedia, and Sirenia.
