Eupleridae

Eupleridae is a family of carnivorans endemic to Madagascar and comprising 10 known living species in seven genera, commonly known as euplerids or Malagasy carnivorans. The best known species is the fossa (Cryptoprocta ferox), in the subfamily Euplerinae. All species of Euplerinae were formerly classified as viverrids, while all species in the subfamily Galidiinae were classified as mongooses.

Recent molecular studies indicate that the 10 living species of Madagascar carnivorans evolved from one ancestor that is thought to have rafted over from mainland Africa 18–24 million years ago. This makes Malagasy carnivorans a clade. They are closely allied with the true herpestid mongooses, their closest living relatives. The fossa and the Malagasy civet (Fossa fossana) are each evolutionarily quite distinct from each other and from the rest of the clade.
