Bd. 46 H. 1-4 S. 143-190 Bonn, Juni 1996 Taxonomy and distributional records of Oriental and European Apodemus, with a review of the Apodemus-Sylvaemus problem G. G. Musser, E. M. Brothers, M. D. Carleton & R. Hutterer Abstract. Specimens of Oriental Apodemus agrarius, A. chevrieri, A. latronum, A. draco, A. semotus, A. gurkha, A. peninsulae, A. speciosus, and A. argenteus that are stored in four natural history museums are documented. Relevant taxonomic and distribu- tional discussion is provided for each species account. Also recorded are series of A. alpicola housed in the American Museum of Natural History and the Field Museum of Natural History. Some of the biochemical and morphological data is evaluated that has been used to support elevating subgenus Sylvaemus to generic rank. We conclude that the species within the genus Apodemus can be separated into three groups rather than two: Apodemus Group (A. agrarius, A. chevrieri, A. speciosus, A. peninsulae, A. latronum, A. draco, A. semotus, A. gurkha); Sylvaemus Group {A. sylvaticus, A. flavicollis, A. uralen- sis, A. mystacinus, A. fulvipectus, A. hermonensis, A. alpicola, A. arianus, A. hyranicus, A. ponticus, A. rusiges, A. wardi); and Argenteus Group {A. argenteus). We further admonish that careful systematic revision of all the species, using biochemical and morphological data in which polarities are determined, is required to test the alternate hypotheses of whether Apodemus is monophyletic or polyphyletic. Key words. Mammalia, Rodentia, Muridae, Apodemus, Sylvaemus, systematics, eastern Asia. Introduction In 1972, Martens & Niethammer reported on samples of two species of Apodemus they had collected in Nepal.
