Abstract
Chromosomes, allozymes, and mitochondrial DNA (mtDNA) were analyzed to examine the taxonomic and systematic relationships of coastal Peromys cus from northern Washington to southern Alaska. All three datasets in dicate that Peromyscus from this region constitute two distinct groups . One group comprises P. oreas, P. sitkensis, and several currently re cognized subspecies of P. maniculatus including P. m. algidus, P. m. h ylaeus, P. m. keeni, P. m. macrorhinus, and P. m. prevostensis. The se cond group comprises only populations of P. m. austerus. The former gr oup is differentiated from the latter by number of autosomal arms, all ele-frequency differences, and mtDNA haplotypes. This dichotomy in kar yotype, and the level of allozymic and mtDNA divergence between the gr oups suggest that the groups constitute distinct species. We recommend that P. oreas, P. sitkensis, P. maniculatus algidus, P. m. hylaeus, P . m. keeni, P. m. macrorhinus, and P. m. prevostensis be recognized un der the specific epithet of Peromyscus keeni.
