Temporal range: Middle Miocene to present
There are twelve extant species of mephitids in four genera: Conepatus (hog-nosed skunks, four species); Mephitis (the hooded and striped skunks, two species); Mydaus (stink badgers, two species); and Spilogale (spotted skunks, four species). The two stink badgers in the genus Mydaus inhabit Indonesia and the Philippines; the other members of the family inhabit the Americas, ranging from Canada to central South America. All other mephitids are extinct, known through fossils, including those from Eurasia.
Skunks were formerly classified as a subfamily of the Mustelidae (the weasel family); however, recent genetic evidence has caused skunks to be treated as a separate family. Similarly, the stink badgers had been classified with badgers, but genetic evidence shows they share a more recent common ancestor with skunks, so they are now included in the skunk family. In alphabetical order, the living species of Mephitidae are:
- Family Mephitidae
- Genus: Conepatus
- Genus: Mephitis
- Genus: Mydaus
- Genus: Spilogale
