title: Cercopithifilaria leporinus n. sp. (Nematoda: Filarioidea) from the snowshoe hare (Lepus americanus Erxleben) (Lagomorpha) in Canada.
abstract: Cercopithifilaria leporinus n. sp. from the subcutaneous tissues of the trunk of snowshoe hares (Lepus americanus Erxleben) in Ontario and Alberta, Canada, is described. This is the only species of Dipetalonema--like filarioid known from lagomorphs. It is distinguished from other species of Cercopithifilaria by its small size, numerous mucrons on the female tail, vulva leading into a large, spherical vestibule and the pattern of papillae on the male tail. Eight species of filarioids, representing four genera, are now known from lagomorphs. Dirofilaria timidi Gubanov and Fedorov, 1966 is considered as a species inquirenda.
