Reithrodontomys megalotis (Baird, 1857)

Western Harvest Mouse

Reithrodontomys megalotis was known from specimens from northwestern Oklahoma, including the counties of Beaver, Cimarron, Texas, and Ellis; an observation was known from Woods County (Caire et al. 1989). Since Caire et al. (1989), few additional specimen records have been reported. Payne et al. (2001) reported the occurrence of this species from Osage County and Braun and Revelez (2005) reported records from Murray and Washita counties. Understanding the distribution of this species in Oklahoma requires additional information. A new record is reported for Roger Mills County in western Oklahoma.
