Both parsimony and distance-based phylogenetic analyses of sequence data from three mitochondrial DNA (mtDNA) genes (ND3, ND4L, and ND4) revealed that, as currently recognized, the Peromyscus maniculatus species group is polyphyletic. This apparent poly-phyly is resolved when P. slevini is removed from the species-group, thus limiting the group to P. maniculatus, P. keeni, P. polionotus, P. sejugis , and P. melanotis . Additionally, the phylogenetic analysis revealed that P. m. coolidgei is closer to P. sejugis than to the other subspecies of P. maniculatus examined. The systematic integrity of P. maniculatus is further complicated by the sister-species relationship between P. keeni and P. sejugis-P. m. coolidgei . These relationships suggest either a high degree of lineage sorting within P. maniculatus or that some of the currently recognized subspecies may be distinct species.
