SPECIES Reithrodontomys (Reithrodontomys) megalotis

Author:Baird, 1857.
Citation:Mammalia in Repts. U.S. Expl. Surv., 8(1): 451.
Common Name:Western Harvest Mouse
Type Locality:México-USA boundary region, between Janos, Chihuahua, and San Luis Springs, Grant Co., New Mexico.
Distribution:SC British Columbia and SE Alberta, Canada; through much of W and NC USA; south to N Baja California Norte and through interior México to C Oaxaca.
Status:IUCN – Lower Risk (lc).
Comments:Subgenus Reithrodontomys, megalotis species group. Formerly included R. zacatecae, which Hood et al. (1984) identified as a separate species. The substantial chromosomal variation reported (see Engstrom et al., 1981) cautions that yet other species are lumped under R. megalotis. Multivariate discrimination from R. montanus in Kansas demonstrated by Hoofer et al. (1999). Recent range expansions into NE Illinois (see Pigage and Pigage, 1994) and within N Texas (Yancey and Jones, 1997) reported; L. Choate (1997) discussed the clinal intergradation between the subspecies aztecus and megalotis on the Llano Estacado, Texas-New Mexico; southern range extension on Baja Peninsula reported by Rios and Alvarez-Castañeda (2002). See Webster and Jones (1982, Mammalian Species, 167).
