Microtus (Alexandromys) maximowiczii Schrenk 1859

Microtus (Alexandromys) maximowiczii Schrenk 1859 , Reisen und Forsch., in: Saugeth. Amurlande St. Petersburg., Vol. 1: 140.

Type Locality: Russia, Chita Oblast, upper Amur region, mouth of Omutnaya River.

Vernacular Names: Maximowicz's Vole.

Synonyms: Microtus (Alexandromys) gromovi Vorontsov, Boeskorov, Ljapunova, and Revin 1988 ; Microtus (Alexandromys) ungurensis Kastschenko 1912 .

Distribution: E shore of Lake Baikal to upper Amur region (Meyer et al., 1996), E Mongolia, and NE China (Heilongjiang, Nei Mongol, Jilin, Hebei, and N Shaanxi; Zhang et al., 1997).

Conservation: IUCN – Lower Risk (lc).

Discussion: Subgenus Alexandromys , maximowiczii species group ( Pavlinov and Rossolimo, 1998; Pavlinov et al., 1995 a; Zagorodnyuk, 1990). Included in subgenus Microtus by Gromov and Polyakov (1977), Pavlinov and Rossolimo (1987), and Meyer et al. (1996). Karyotypic, morphological and hybridization evidence closely relates M. maximowiczii to M. mujanensis and M. evorensis (Meyer et al., 1996) . Reviewed by Orlov and Kovalskaya (1978) and Meyer (1983). Populations in Russia revised by Meyer et al. (1996), who attributed the two synonyms. Additional intraspecific chromosomal polymorphisms analysed by Kovalskaya (1977). Molar variation in the M. maximowiczii species group, as analyzed by Pozdnyakov (1993), reveals significant differences between maximowiczii from the Amur region and other geographic samples.
