| The Chihuahuan Pocket Mouse differs only slightly in appearance from the Desert Pocket Mouse (Chaetodipus penicillatus) but there is little overlap in their geographic ranges. The Chihuahuan Pocket Mouse is a bit larger and lighter than its cousin and is found in the Chihuahua desert in southern New Mexico, western Texas, and parts of northeastern Mexico (Chihuahua, Coahuila de Zaragoza, Durango and Zacatecas). Genetic markers have provided the evidence that this is indeed a different species from C. penicillatus, its western cousin.
