Euplerinae is a subfamily of carnivorans that includes four species restricted to Madagascar. Together with the subfamily Galidiinae, which also only occurs on Madagascar, it forms the family Eupleridae. Members of this subfamily, which include the fossa (Cryptoprocta ferox), falanoucs (Eupleres goudotii and Eupleres major) and Malagasy civet (Fossa fossana), were placed in families like Felidae and Viverridae before genetic data indicated their consanguinity with other Madagascar carnivorans. Within the subfamily, the falanouc and Malagasy civet are more closely related to each other than to the fossa.
