discussion

Discussion: Sylvaemus group. Previously listed as a subspecies of A. sylvaticus (Corbet, 1978 c; Ellerman and Morrison-Scott, 1951; Pavlinov and Rossolimo, 1987), but now recognized as the oldest name for a distinctive small-bodied species formerly called A. microps (Musser and Carleton, 1993; Pavlinov and Rossolimo, 1998; Pavlinov et al., 1995 a). Synonymy of European microps with Asian uralensis has been documented by results of a variety of molecular and morphological studies (Bellinvia et al., 1999; Filippucci et al., 1996; Macholán et al., 2001 b; Mezhzherin, 1997 a; Mezhzherin and Mikhailenko, 1991; Mezhzherin and Zykov, 1991; Mezhzherin et al., 1992; Reutter et al., 2003). Mezhzherin (1997 b: 309) summarized historical literature indicating the presence of a species different from A. sylvaticus that corresponded to A. uralensis. Pertinent systematic treatments cover chromosomal and allozymic variation (as microps; Gemmeke, 1983; Mezhzherin, 1997 b; Vorontsov et al., 1989, 1992); morphological data presented in context of distinguishing species of Apodemus (Tvrtkovic and Dzukic, 1977); variation in banded chromosomes between A. uralensis (as microps) and A. alpicola (Reutter

discussion

COMMENTS: Subgenus Sylvaemus. Listed as a subspecies of A. sylvaticus by Ellerman and Morrison-Scott (1951), who also noted that Kuznetzov (in Bobrinskii et al., 1944) had already suspected that the Altai tscherga and uralensis refered to the same species. This identity, including those of most of the synonyms, is documented by biochemical and morphological results (Mezhzherin and Mikhailenko, 1991; Mezhzherin and Zykov, 1991). Gemmeke (1983) and Vorontsov et al. (1989, 1992) also provided chromosomal and biochemical information (under microps), and Tvrtkovic and Dzukic (1977) provided morphological data in context of distinguishing species of Apodemus. Ma et al. (1987) and Pavlinov and Rossolimo (1987) treated tscherga as a subspecies of A. sylvaticus, but Corbet (1978 c) listed it under A. peninsulae. The NW Chinese nankiangensis was described as a subspecies of A. sylvaticus (see Corbet, 1984; Ma et al., 1987); we provisionally include it and three of the other synonyms (pallidus, balchaschensis, and pallipes) pending a systematic revision of E Russian, Middle Eastern, and W Chinese Apodemus.
