Species
This species was formerly known as prairie spotted skunk (Spilogale putorius ssp. interrupta). A recent phylogenetic study of spotted skunks (McDonough et al., 2022) resulted in a major taxonomic revision. It showed that the four species in the genus Spilogale actually represents seven distinct species. Spilogale putorius ssp. interrupta was to full species status. The name Spilogale putorius is now the Alleghnian spotted skunk, which occurs in the southeastern US except the east coast and the Appalachians north into Pennsylvania.
