Variation at 21 allozyme loci and 10 restriction enzymes within the mitochondrial DNA control region was assessed among 3 allopatric populations of montane vole (Microtus montanus) in the American Southwest. Among populations of M. montanus, the population from the White Mountains, Arizona, was most genetically divergent. Genetic and biogeographic evidence supported recognition of the White Mountains population as a distinct subspecies, M. m. arizonensis. Results also supported recognition of the Mogollon vole (Microtus mogollonensis) as distinct from the Mexican vole (Microtus mexicanus).
