SPECIES Megadontomys cryophilus

Author:Musser, 1964.
Citation:Occas. Pap. Mus. Zool., Univ. Michigan, 636: 13.
Common Name:Oaxacan Big-toothed Deermouse
Type Locality:México, Oaxaca, Distrito de Ixtlán, 13 mi (21 km) NE Llano de las Flores, south slope Cerro Pelón, 9200 ft (2804 m).
Distribution:Cloud and pine-oak forests in highlands of N Oaxaca, México.
Status:IUCN – Lower Risk (nt).
Comments:Named as a subspecies of Peromyscus thomasi. Citing morphological traits and genetic differentiation reported by Werbitsky and Kilpatrick (1987), Carleton (1989) arranged cryophilus as a species. Recent elevational surveys by Briones-Salas et al. (2001) in the Sierra Mazteza and Sánchez-Cordero (2001) in the Sierra Mixteca amplify the geographic occurrence of this species in Oaxaca.
