A redescription of Chabaudus leberrei (Bain & Philippon, 1969) (Nematoda: Seuratoidea) from Xenopus spp. in Swaziland

Chabaudus leberrei (Bain & Philippon, 1969) is redescribed from the pipid anurans Xenopus muelleri (Peters) and X. laevis laevis (Daudin) (new host records) in northern Swaziland, based on light and scanning electron microscope studies. The six anterior protuberances characteristic of the genus Chabaudus Inglis & Ogden, 1965, are, in C. leberrei, formed by bipartite lamellae associated with the internal margins of the three lips. Intraspecific variation in the number and disposition of male caudal papillae and in the development of the cephalic vesicle is documented.
