SPECIES Microtus (Pitymys) quasiater

Author:Coues, 1874.
Citation:Proc. Acad. Nat. Sci. Philadelphia, 26: 191.
Common Name:Jalapan Vole
Type Locality:México, Veracruz, Jalapa.
Distribution:Eastern slopes of the Sierra Madre Oriental, 500-2150 m, SE San Luis Potosi to N Oaxaca, México (Ramírez-Pulido et al., 1991:Fig. 1).
Status:IUCN – Lower Risk (lc).
Comments:Subgenus Pitymys. Named as a variety of M. pinetorum but specific status affirmed thereafter (Bailey, 1900; Hall and Cockrum, 1953; Repenning, 1983). Typically viewed as most closely related to pinetorum in subgenus or genus Pitymys (Anderson, 1960; Hall and Cockrum, 1953; van der Meulen, 1978), a convention challenged by Repenning (1983) and Moore and Janecek (1990), who supported sister-group kinship between ochrogaster and quasiater. Closest kinship with M. pinetorum, however, reaffirmed in phylogenetic analysis of cytochrome b sequences that included M. ochrogaster and 16 other species of North American Microtus (Conroy et al., 2001). Nongeographic variation, distribution, and natural history summarized by Ramírez-Pulido et al. (1991); nonbanded karyotype reported by Cervantes et al. (1994) and compared with other Mexican species.
