          Abstract

          En este trabajo se presenta una lista actualizada de las especies de mamíferos terrestres de Oaxaca. Se analizó la riqueza acumulada, los patrones espaciales de riqueza, endemismo, estado de conservación y la diversidad beta taxonómica. La información proviene de recolectas recientes y se complementa con los registros de ejemplares depositados en colecciones científicas y de literatura especializada. Los resultados obtenidos muestran que a partir de la década de 1960 se incrementó el esfuerzo de recolecta; actualmente se conocen 28,060 registros. La composición taxonómica en Oaxaca está representada por 216 especies, incluyendo 48 monotípicas y 168 politípicas con 209 subespecies; esto suma un total de 257 taxones. La mayor riqueza de especies se registró en las subprovincias fisiográficas: Sierra Madre de Oaxaca (154), Planicie Costera de Tehuantepec (135) y Sierra Madre del Sur (127). La baja similitud taxonómica entre subprovincias (0.36-0.82) explica la elevada diversidad de mamíferos en Oaxaca.

          Translated abstract

          In this study we present an updated taxonomic list of the terrestrial mammals of Oaxaca. The accumulated species richness, spatial richness patterns, endemicity, conservation status and taxonomic beta diversity was analyzed. We considered specimens deposited in mammal collections, and specialized literature. The results show that from the 1960's the collection effort increased, until the 28,060 records were obtained. The taxonomic composition of terrestrial mammals in Oaxaca is represented by 216 species, including 48 monotypic and 168 polytypic with 209 subspecies, a total of 257 taxa. The highest species richness occurs in the Sierra Madre de Oaxaca (154) and the Coastal Plain of Tehuantepec (135) and Sierra Madre del Sur (127). The low taxonomic similarity between subprovinces (0.36 to 0.82) explains the great diversity of mammals in Oaxaca.

              Diversification of the arboreal mice of the genus Habromys (Rodentia: Cricetidae: Neotominae) in the Mesoamerican highlands.

              The arboreal mice of the genus Habromys (Rodentia: Cricetidae: Neotominae) are among the most poorly known Neotropical rodents. We investigated species-level phylogenetic relationships among the seven described Habromys species using 1331 aligned bases from the mitochondrial ND3 and ND4 regions. Sequences were obtained from 30 specimens of the seven known species of Habromys and we performed maximum parsimony, maximum likelihood, and Bayesian probabilities analyses. The monophyly of the genus Habromys within the Neotomines was verified. The northernmost H. simulatus is sister to the remaining species of the group; within the latter, the southernmost clade (Oaxaca to Central America) is sister to the Transmexican Volcanic Belt clade. Four major clades are clearly distinguished: H. simulatus from the Sierra Madre Oriental and the closely associated Sierra Mazateca; H. delicatulus and H. schmidlyi from the Transmexican Volcanic Belt; H. lepturus, H. chinanteco, and H. ixtlani from the northern Oaxacan highlands; and H. lophurus from Nuclear Central America. Within species, the analyses suggest that H. simulatus and H. lophurus are each composed by two different taxa.
