英文摘要	The genus Notiosorex is the only group of shrews in North America with adaptations to arid or semiarid zones. The genus was described with a single variable species, Notiosorex crawfordi, from which 5 new species have since been distinguished. To date, the phylogenetic relationships of Notiosorex species have only been partially analyzed and it is possible that there are still distinct species included within the catch-all of N. crawfordi. Here, we use geometric morphometrics on cranial and mandibular characters of the described extant species, 3 fossil species, and a distinctive population of N. crawfordi as a proxy for an integrated assessment of phylogenetic relationships of all Notiosorex species. Our results indicate that the population from the Altiplano Mexicano is more similar to, yet distinct from, N. villai than it is to N. crawfordi-we describe it as a new species. We also used the resulting tree to reconstruct phylogeographic history within the genus, which suggests that Notiosorex sp. nov., N. villai, N. evotis, and N. tataticuli all diverged allopatrically as populations from the ancestral area that is currently occupied by N. crawfordi (and in the deeper past by the fossil species N. harrisi), and pushed south into the Gulf Coast, the Altiplano, and Baja California within the last 5 million years following the end of the Miocene. The genus Notiosorex includes the shrews of North America with adaptations to arid or semiarid zones. Notiosorex has 5 species and we describe a new species from the Altiplano Mexicano, analyzing fossil and the living species. We also used the resulting tree to reconstruct phylogeographic history within the genus. El g & eacute;nero Notiosorex es el & uacute;nico grupo de musara & ntilde;as con adaptaciones a zonas & aacute;ridas y semi & aacute;ridas en Norteam & eacute;rica. El g & eacute;nero fue descrito con base en una sola especie muy variable, Notiosorex crawfordi; desde ese entonces, se han descrito cinco nuevas especies. Hasta la fecha, las relaciones filogen & eacute;ticas de las especies dentro del g & eacute;nero Notiosorex solo han sido analizadas parcialmente, y es posible que haya a & uacute;n mayor n & uacute;mero de especies nuevas incluidas dentro del grupo general de N. crawfordi. En este estudio, utilizamos morfometr & iacute;a geom & eacute;trica del cr & aacute;neo y mand & iacute;bula de las especies vivas ya descritas, adem & aacute;s de tres especies f & oacute;siles, y una poblaci & oacute;n distintiva de N. crawfordi del Altiplano Mexicano como un indicador para una evaluaci & oacute;n integrada de las relaciones filogen & eacute;ticas de todas las especies de Notiosorex. Nuestros resultados indican que la poblaci & oacute;n del Altiplano Mexicano es m & aacute;s similar y claramente diferenciable de N. villai que de N. crawfordi, y la describimos como una nueva especie. Utilizamos el & aacute;rbol filogen & eacute;tico para reconstruir la historia filogeogr & aacute;fica del g & eacute;nero, lo que sugiere que esta nueva especie del Altiplano, junto con N. villai, N. evotis y N. tataticuli, todas divergieron de forma alop & aacute;trica como poblaciones separadas a partir de la zona ancestral que actualmente ocupa N. crawfordi (y en el pasado m & aacute;s antiguo, por la especie f & oacute;sil N. harrisi) y se desplazaron hacia el sur, hacia la costa del Golfo, el Altiplano y Baja California en los & uacute;ltimos 5 millones de a & ntilde;os, desde finales del Mioceno.
