Apodemus peninsulae (Thomas, 1907) . Proc. Zool. Soc. Lond., 1906:862 [1907].

TYPE LOCALITY: Korea, 110 m SE of Seoul, Mingyoung .

DISTRIBUTION: SE Siberia from NE China (Xinjiang) and Altai Mtns to Ussuri, south through NE China and Korea, and E Mongolia to SW China (Sichuan and E Xizang); also on N Japanese islands of Sakhalin and Hokkaido.

SYNONYMS: giliacus, major, majusculus, nigritalus, praetor, qinghaiensis, rufulus, sowerbyi .

COMMENTS: Subgenus Alsomys . The Chinese qinghaiensis was described as a subspecies (Feng et al., 1983). Results of B-chromosomal analyses and references to chromosomal studies of A. peninsulae provided by Kolomiets et al. (1988) and Borisov and Malygin (1991). Biochemical systematics in reference to A. speciosus and the Hokkaido giliacus reported by Saitoh et al. (1989), who also reviewed the contrasting treatment of giliacus as either a subspecies of A. peninsulae or a separate species, and its bigeographical implications. Corbet (1978c) listed nigritalus as a synonym of A. sylvaticus, but the holotype is A. peninsulae (also see Pavlinov and Rossolimo, 1987:221). A. peninsulae nigritalus is sympatric with the smaller-bodied A. uralensis tscherga in the Altai region, which Hollister had noted (but under different names) in 1913b (see Ellerman and Morrison-Scott, 1951:567). Placed in subgenus Apodemus by Pavlinov and Rossolimo (1987) and Mezhzherin and Zykov (1991).
