A new record and phylogenetic position of Notiosorex crawfordi (Eulipotyphla, Soricidae) with distribution in Zacatecas, Mexico, using mitochondrial DNA

A unique record of the desert shrew in Zacatecas, Mexico, is known and has been collected since 1897 in the locality "El Plateado" within the municipality of El Plateado de Joaquin Amaro, Zacatecas. On October 2016, two specimens were collected from the municipality of Susticacan, Zacatecas, Mexico. A morphological identification and phylogenetic analysis based on partial sequences of cytochrome b oxidase of mitochondrial DNA (mtDNA) were implemented. Morphology and the phylogenetic trees that were recovered by using maximum-likelihood (ML) confirmed the identity of these specimens as Notiosorex crawfordi. This is the second record for the species in Zacatecas, Mexico, after 121 years.
