Range: As the most common small mammal in Korea, the distribution of A. agrarius covers most of the Korean Peninsula and most islands (except Jeju Island; Jo et al. 2017b; Fig. 130 ).

Remarks: Jones and Johnson (1965) reported four subspecies of A. agrarius principally based on body color and size: mantchuricus in the extreme northern part of the peninsula, pallescens in the coastal lowlands of southern Korea; coreae throughout a significant portion of the peninsula; and chejuensis on Jeju Island. Koh (1986, 1987, 1991) and Koh and Yoo (1992) proposed placing pallenscens as a synonym of A. agrarius coreae . Populations on the mainland and the two islands, Jeju Island and Wan Island had significant genetic differences ( Koh 1986). However, three mainland localities shared several haplotypes, suggesting a considerable gene flow among populations. A morphometric study of these populations found two distinct morphotypes ( coreae , small-sized group; chejuensis , large-sized group) and implied different species ( Koh 1986). Recent microsatellite analysis ( Jo et al. 2017b) showed that populations of striped field mouse on Heuksan Island, Jeju Island, and mainland clustered in three different groups. Additional studies are needed to resolve the taxonomy of Apodemus in Korea.
