Abstract:

Peromyscus maniculatus (Wagner, 1845) and Peromyscus keeni Merriam, 1897 are two species of deer mouse currently recognized in the Yukon. Phylogenetic analyses (Kimura two-parameter and maximum parsimony) of cytochrome-b sequences (560 base pairs) from deer mouse specimens (n = 4) collected near Haines Junction, Yukon, resulted in a monophyletic clade genetically distant from the two currently recognized species. We suggest that the Haines Junction specimens may represent a previously undescribed peromyscine species. Peromyscus arcticus is an available name.

Peromyscus maniculatus (Wagner, 1845) et Peromyscus keeni Merriam, 1897 sont deux espèces de souris à pattes blanches actuellement reconnues au Yukon. Des analyses phylogénétiques (distance à deux paramètres de Kimura et parcimonie maximale) des séquences du cytochrome-b de spécimens (n= 4) de souris à pattes blanches récoltés près de Haines Junction, Yukon, on révélé l'existence d'un clade monophylétique à distance génétique égale des deux espèces actuellement reconnues. Nous croyons que les spécimens de Haines Junction représentent peut-être une espèce encore inédite de péromyscinés. Peromyscus arcticus est un nom disponsible pour cett espèce.
