Abstract

Four external and 27 cranial characters of Korean field mice (Apodemus peninsulae) from nine regions in China and Korea, representing three subspecies, were analyzed by multivariate methods. Four size-forms were recognized a largest-size form Mt. Weolak and Yeoncheon in Korea (= subspecies peninsulae) and Kirin and Heilung in China (= subspecies praetor), a large-size form from Inner Mongolia in China (= subspecies praetor) and Sanxi and Sandong in China (= subspecies sowerbyi), a middle-size form from Beijing in China (= subspecies sowerbyi), and a small-size form from Xinjiang in China (= subspecies sowerbyi). Although Corbet (1978) recognized only two subspecies in A. peninsulae, subspecies peninsulae and sowerbyi, within its distributional range in the continent of Asia, it was revealed in this study with morphometric characters that A. peninsulae could not be classified simply into two subspecies, because subspecies praetor and subspecies sowerbyi formed the large-size form and because subspecies sowerbyi was so diverse in its morphology as to be composed of three size-forms. Further analyses with the samples from other regions of China and Russia seem to be necessary to clarify the taxonomy of A. peninsulae.
