Chaetodipus nelsoni出现在墨西哥高原的岩石基底上。我们利用形态学、核型和分子数据调查了该物种的地理多样性。从核（AFLP）和线粒体DNA的数据支持三个不同的遗传群体与最小的亚结构相一致，以前确定在奇瓦瓦沙漠和高原流域流域的地理障碍。我们根据分子数据检查了形态学和核型数据。这些结果支持目前公认的三个物种的识别。nelsoni：1）C. nelsoni仅分布于El Salado河流域; n. collisto种，有两个亚种：一个分布于德克萨斯州的外佩科斯，另一个分布于马皮米盆地（新亚种）; durangae，以Nazas盆地和上Río Mezquital流域为中心。
Chaetodipus nelsonioccurs on rocky substrates across the Mexican Altiplano. We investigated phylogeographic diversity within the species using morphologic, karyotypic, and molecular data. Data from nuclear (AFLP) and mitochondrial DNA support three distinct genetic groups with minimal substructuring coincident with biogeographic barriers previously identified in the Chihuahuan Desert and drainage basins of the Altiplano. We examined the morphological and karyotypic data in light of the molecular data. The results support recognition of three species within the currently accepted widespreadC. nelsoni: 1)C. nelsonirestricted to a distribution centered on the El Salado River Basin; 2) elevation ofC. n. collisto species, with two subspecies: one centered on Trans-Pecos Texas, the other on the Mapimí Basin (new subspecies); and 3) recognition of a new species,C. durangae, centered on the Nazas Basin and upper Río Mezquital drainage.
