Mearns's grasshopper mouse or the Chihuahuan grasshopper mouse (Onychomys arenicola) is a grasshopper mouse found in southwestern New Mexico, West Texas, and north-central Mexico. They are similar to Onychomys torridus, but differ in karyotype and size. This mouse is smaller in every regard except for the nasal length of the skull.[3]
