SPECIES Microtus (Pitymys) oaxacensis

Author:Goodwin, 1966.
Citation:Am. Mus. Novit., 2243: 1.
Common Name:Tarabundí Vole
Type Locality:México, Oaxaca, Ixtlán Dist., near Vista Hermosa, Tarabundí Ranch, 5000 ft (1524 m).
Distribution:Eastern slopes, Sierra de Juárez, 1600-2500 m, NC Oaxaca, México.
Status:IUCN – Lower Risk (nt).
Comments:Subgenus Pitymys. Differentially diagnosed with respect to M. mexicanus and M. umbrosus by Goodwin (1966); description amplified and resemblance to M. guatemalensis noted by Jones and Genoways (1967), an affinity supported by their dental and genetic similarity (Conroy et al., 2001; R. A. Martin, 1995). Grouped with other relictual "pitymyine" species found at southern edge of the Nearctic Microtus distribution by Hoffmann and Koeppl (1985), a biogeographic interpretation supported by Conroy et al. (2001). Karyotype reported by Cervantes et al. (1997), who noted its derived condition compared with other New World Microtus. Altitudinally parapatric distribution with respect to M. mexicanus illuminated by Sánchez H. et al. (1996). See Frey and Cervantes (1997, Mammalian Species, 556).
