Amer. Fauna, 21: 64 . Type Locality: USA , Alaska , Cook Inlet, Turnagain Arm, head of Bear Creek in mountains near Hope City. Vernacular Names: Singing Vole . Synonyms: Microtus andersoni Rand 1945 ; Microtus cantator Anderson 1947 ; Microtus muriei Nelson 1931 ; Microtus oreas Osgood 1907 ; Microtus paneaki Rausch 1950 . Distribution: Alaska , USA , except the central portion and Alaska Peninsula; eastwards through much of Yukon Territory to westernmost Northwest Territories and extreme NW British Columbia , Canada . Conservation: IUCN – Lower Risk (lc). Discussion: Subgenus indeterminate. Classically treated as a member of the subgenus Stenocranius (e.g., Hall, 1981 ; Miller and Kellogg, 1955 ), an association that purported close affinity to Old World M. gregalis (see that account); synonymized with same to form a Holarctic species by Rausch (1964) and Rausch and Rausch (1968) . Other data convincingly argue their specific distinctiveness and distant kinship ( Anderson, 1960 ; Fedyk, 1970 ; Gromov and Polyakov, 1977 ; Vorontsov and Lyapunova, 1986 ), and phylogenetic studies of chromosomes ( Zagorodnyuk, 1990 ) and mitochondrial DNA sequences ( Conroy and Cook, 2000 a ) require the removal of M. miurus (along with M. abbreviatus ) from Stenocranius proper. Zagorodnyuk (1990) had emphasized this divergence by placing M. miurus in the subgenus Alexandromys , M. middendorfii species group, along with M. mongolicus and M. sachalinensis . According to the results of Conroy and Cook (2000 a ) , M. miurus , and its sister species M. abbreviatus , originated early within the radiation of North American Microtus , apart from Palearctic species.
