Abstract

Systematic relationships of southern populations of short-tailed shrews (genus Blarina) are assessed on the basis of karyotypic data and univariate and multivariate analyses. The analyses show that the populations can be separated into two phena. The southwestern phenon is significantly larger and has a karyotype of 2N=52, FN=60, 61, or 62; the southeastern phenon is smaller and has a karyotype of 2N=37, 38, 39, or 46, FN=44. The phena apparently represent distinct species. The name Blarina hylophaga is available for the southwestern species, and the name Blarina carolinensis should be restricted to the southeastern species of short-tailed shrews.
