Abstract 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 Susticacán, 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.

使用线粒体 DNA 在墨西哥萨卡特卡斯州分布的 Notiosorex crawfordi (Eulipotyphla, Soricidae) 的新记录和系统发育位置

摘要 墨西哥萨卡特卡斯沙漠鼩鼱的独特记录是众所周知的，自 1897 年以来一直在萨卡特卡斯州 El Plateado de Joaquin Amaro 市内的“El Plateado”地区收集。2016 年 10 月，从墨西哥萨卡特卡斯州苏斯蒂卡坎市收集了两个标本。基于线粒体DNA（mtDNA）的细胞色素b氧化酶的部分序列进行了形态学鉴定和系统发育分析。使用最大似然法 (ML) 恢复的形态学和系统发育树证实了这些标本的身份为 Notiosorex crawfordi。这是该物种在墨西哥萨卡特卡斯 121 年后的第二项记录。
