Range: The Korean field mouse commonly occurs throughout Korea, except in remote islands ( Fig. 128 View FIGURE 128 ).

Remarks: Due to morphological differences such as the number of mammae, skull, and teeth, Jones (1956) promoted peninsulae to a distinct species. The presence of three region-specific mtDNA types of ancient divergence likely resulted from the regions of Primorye, Siberia and the Korean Peninsula functioning as refugia for A. peninsulae during a substantial period of the Quaternary glacial ages ( Serizawa et al. 2002). According to a phylogenetic study based on cytochrome b, the Korean population is closer to populations from Shandong and Ningxia, China than from those of the Russian Far East ( Sakka et al. 2010). A numerical taxonomy and genetic study suggests the occurrence of two subspecies ( A. p. peninsulae and A. p. sowerbyi) in Korea (Heo 2002).
