Microtus (Alexandromys) sachalinensis Vasin 1955

Microtus (Alexandromys) sachalinensis Vasin 1955, Zool. Zh., 34: 427.

Type Locality: Russia, Sakhalin Isl, Poronaysk region, Olen River.

Vernacular Names: Sakhalin Island Vole.

Distribution: Endemic to Sakhalin Isl (Dobson, 1994).

Conservation: IUCN – Lower Risk (nt).

Discussion: Subgenus Alexandromys, middendorfii species group (Zagorodnyuk, 1990) or maximowiczii species group (Pavlinov and Rossolimo, 1998; Pavlinov et al., 1995 a). The latter species group association more accurately reflects data synthesized from karyological, morphological, and hybirdization studies, which phylogenetically link M. sachalinensis most closely to M. maximowiczii within the subgenus Alexandromys (Meyer et al., 1996) .
