Abstract	Three species of shrews of the genus Blarina inhabit the central and eastern U.S. —B. brevicauda, B. hylophaga, and B. carolinensis. These shrews are quite similar morphologically, and prior to 1972 they were considered a single species (B. brevicauda). Genoways and Choate (1972) and Genoways et al. (1972) separated B. brevicauda into two species (B. brevicauda and B. carolinensis) by elevating B. brevicauda carolinensis. Later, George et al. (1981, 1982) split B. carolinensis into two species (B. carolinensis and B. hylophaga) based on karyotypic and morpholologic data. They described the distribution of B. brevicauda as extending south to Platte, Randolph, and Ralls counties of Missouri (George et al. 1982), with a broad area of sympatry with B. hylophaga occurring across southern Iowa and northern Missouri. Thompson et al. (2011) examined this purported area of sympatry (using karyotypic and nuclear DNA markers) and found that the two species occurred parapatrically rather than sympatrically. Within their study area, B. hylophaga was found to occur in two counties of southern Iowa (Fremont and Page) and three counties of northern Missouri (Atchison, Holt, and Nodoway). Since shrews from the southernmost extent of their study area (Platte, Clay, and Ray counties) were identified as B. brevicauda, the southern limit of the range of B. brevicauda must be south of those counties. Additionally, Webster et al. (2011) extended the distribution of B. brevicauda into northeastern Kansas (based on morphologic data)
