[New filaria of the Cercopithifilaria genus, parasite of an African carnivore].

Description of Cercopithifilaria corneti sp. n., a parasite of the subcutaneous tissues of Nandinia binotata, is given. With its 16 species parasitizing a variety of mammals from all over the world, the genus Cercopithifilaria has a homogeneous morphology and a uniform biology (dermal microfilariae, ixodid vectors). It is suggested that the unexpected host range is the consequence of particular speciation phenomena in relation to the biology of Ixodidae.
