%X En este trabajo se documenta la riqueza de mam¨ªferos del Parque Nacional Barranca del Cupatitzio, Michoac¨¢n, M¨¦xico, registrada de abril de 2003 a octubre de 2004 mediante diversos m¨¦todos de campo. Se identificaron 43 especies, pertenecientes a 8 ¨®rdenes, 16 familias y 32 g¨¦neros. El estimador no param¨¦trico ACE indic¨® que podr¨ªan registrarse al menos 13 especies m¨¢s y que se logr¨® detectar el 77% de las que posiblemente existen en el parque. Los mam¨ªferos voladores constituyeron el 25.6% del total de las especies y los no voladores el 74.4%. Hay 7 especies (16.3%) end¨¦micas de M¨¦xico, 5 (11.6%) end¨¦micas de Mesoam¨¦rica, 10 (23.3%) compartidas con Norteam¨¦rica, 7 (16.3%) con Sudam¨¦rica, 13 (30.2%) con Norte y Sudam¨¦rica, y 1 es ex¨®tica (2.3%). Por sus afinidades biogeogr¨¢ficas, 22 especies (52.4%) son ne¨¢rticas, 16 (38.1%) neotropicales y 4 (9.5%) transicionales. (4.7%) La lista de la Norma Oficial Mexicana 059 incluye 2 especies:, 1 en peligro de extinci¨®n (Leopardus wiedii) y 1 amenazada (Crateogomys fumosus). Se identificaron 8 especies prioritarias para su conservaci¨®n considerando criterios de riesgo, endemismo y restricci¨®n de distribuci¨®n. No obstante su poca superficie y ubicaci¨®n en una zona de crecimiento urbano, Barranca del Cupatitzio es un ¨¢rea de importancia para la conservaci¨®n de la diversidad de mam¨ªferos, ya que protege poco m¨¢s de la cuarta parte de las especies de Michoac¨¢n. In this paper we present field information on mammal richness from Barranca del Cupatitzio National Park, Michoac¨¢n, Mexico, recorded from April 2003 to October 2004, by means of specimen collection, visual detection, photo trapping and search of remains, signs and tracks. The area is covered mainly by closed canopy conifer forests. The mammal richness of this park was 43 species belonging to 8 orders, 16 families and 31 genera. The non-parametric ACE estimator indicated that 77% of all possible species were recorded and at least 13 more species can be potentially found. From all species recorded, 25.6% were flying mammals and 74.4% were non-flying. The distribution of species shows that 7 mammals (16.3%) are endemic to Mexico, 5 (11.6%) are endemic to Meso America, 10 (23.3%) are shared with North America, 7 (16.3%) with South America, 13 (30.2%) with North and South America, and 1 is exotic (2.3%). Considering their biogeographic affinities, 22 species (52.4%) are Neartic, 16 (38.1%) are Neotropical and 4 (9.5%) are transitional. Two species (4.7%) are considered at risk by Mexican regulations: 1 in danger of extinction (Leopardus wiedii) and 1 as threatened (
