Taxonomy, geographic distribution, and morphological variation in context of defining species in subgenus Terricola reported by Zagorodnyuk (1989, 1992); karyotypic information presented by Sablina et al. (1989), Zima (1986), and Zima and Krâl (1984a); biochemical comparisons among M. subterraneus, M. felteni, and other voles documented by Gill et al. (1987). Synonyms referenced according to Zagorodnyuk (1989), who speculated that dacius is a separate species.
