Abstract
We evaluated the taxonomic status of three specimens of gray shrews, Notiosorex (Insectivora: Soricidae), collected in isolated mountain valleys in Tamaulipas, Mexico, with specimens referable to the Recent taxa N. crawfordi crawfordi (n = 229) and N. c. evotis (n = 34). Statistical analyses of cranial morphometric data revealed that the specimens from Tamaulipas represented a heretofore unknown taxon which is described herein as a new species of Notiosorex (N. villai). Also, N. c. evotis was found to be equally distinct from N. c. crawfordi, thus was elevated to specific status.
Resumen---Se evaluó el estado taxonómico de tres especímenes de la musaraña gris Notiosorex (Insectivora: Soricidae), colectados en valles dentro de las motañas en Tamaulipas, México y referidos a los taxa recientes N. crawfordi crawfordi (n = 229) y N. c. evotis (n = 34). Análisis estadísticos morfométricos del cráneo indicaron que los especímenes de Tamaulipas representan un taxón desconocido, el cual se describe como una especie nueva de Notiosorex (N. villai). Asimismo, N. c. evotis se encontró distinto a N. c. crawfordi, por lo que se elevó aI nivel específico.
