The current documented Reithrodontomys fulvescens (Fulvous Harvest Mouse) distribution includes western Mississippi. Here, we report new geographic distribution records in east-central Mississippi. We conducted live-trapping in Kemper County, MS, during the summers of 2011–2015, and captured both Fulvous Harvest Mice and Reithrodontomys humulis (Eastern Harvest Mouse). We compared measurements from captured Fulvous and Eastern Harvest Mice to verify presence of both species. Our results showed 2 separate clusters of measurements, independent of our species assignment in the field, and the clusters were significantly different (P < 0.01). It is unclear whether these new records represent a range expansion or new information about the species' historical distribution.
