    Notes: Abstract An intestinal capillariid nematode, Aonchotheca musimon n. sp., is described from Ovis musimon imported into the Kerguelen archipelago (Terres Australes et Antarctiques Françaises). The comparison of this new material with other Aonchotheca spp. is based on the usual characters, i.e. spicule, caudal bursa, number of papillae, stichosome, bacillary bands, shape of the cirrus, and on the length of the ejaculatory duct which appears to be of some phylogenetic value. A. musimon, of which the spicule is 208–230 μm long, is close to A. bilobata, another parasite of bovids, which is redescribed here. It is distinct from this species because the posterior region of the female worm is cylindrical instead of conical, the lateral alae of the male worm are longer, quadrangular and vesicular instead of triangular and smooth, the caudal bursa has a folded dorso-lateral edge, there is a recurrent ventral fold of the cirrus, the slender distal part of the spicule is longer, the oesophagus is shorter in both sexes and the slightly larger eggs have a thicker shell. These two species from bovids and A. murissylvatici from murid rodents, of which the main characters are similar, represent a small group with a very elongate ejaculatory duct (1.9–2.5 mm). This is in contrast to a larger group of species with a short ejaculatory duct (350–600 μm), which are parasites of Chiroptera (A. brosseti, A. chabaudi, A. landauae, A. gabonensis), Insectivora (A. erinacei), mustelid Carnivora (A. putorii, A. mustelorum) and glirid rodents (A. myoxinitelae, A. legerae). A. bovis and A. dessetae, respectively parasites of bovids and lagomorphs, present an ejaculatory duct of intermediary length and do not belong to these groups. Several species are tranferred to the genus Aonchotheca: A. kashmirensis (Raina & Kaul, 1982) n. comb., A. legerae (Justine, Ferté & Bain, 1987) n. comb., A. forresteri (Kinsella & Pence, 1987) n. comb., A. chabaudi (Justine, 1989) n. comb., A. landauae (Justine, 1989) n. comb., A. brosseti (Justine, 1989) n. comb., A. gabonensis (Justine, 1989) n. comb. and A. dessetae (Justine, 1990) n. comb.

    Notes: Abstract Madathamugadia hiepein. sp., Splendidofilariinae, a parasite of a South African gecko Pachydactylus turneri is described together with its development obtained experimentally in Phlebotomus duboscqi (Diptera: Psychodidae: Phlebotominae). This new species differs from the two small, more highly evolved groups with a short tail and atrophied postcloacal papillae, the first group consisting of two Madagascan species, M. zonosauri and M. hopluri, parasites of the Gerrhosauridae and Iguanidae, and the second containing three species from the Ethiopian Region, M. huambensis, M. versterae and M. bissani, parasites of the Scincidae. It also differs from M. ineichi, the most primitive species of the genus (cuticularised buccal capsule, no atrophy of head papillae and largest number of precloacal papillae), a parasite of the Cordylidae in South Africa. M. hiepei is close to the two species parasitic in the Gekkonidae of the Mediterranean subregion, M. ivaschkini and M. wanjii, all three of which have a post-oesophageal vulva. However, the new species can be distinguished from the Mediterranean parasites by (a) the shorter oesophagus, (b) the number and position of the cloacal papillae and (c) the microfilaria. The three filariae of this group and M. ineichi, the only ones of which aspects of the life-cycles are known, experimentally develop in phlebotomine sand flies.

    Notes: Résumé Etude morphologique du genre Passalurus Dujardin, 1845. Passalurus comprend deux espèces: P. ambiguus (Rudolphi, 1819) et P. nonanulatus Skinker, 1931. P. assimilis Wu, 1933 chez Lepus sinensis (Chine) est synonyme de P. nonanulatus. P. abditus Caballero, 1937 chez un Otospermophilus mexicain est retiré du genre et devient Citellina abdita n. comb. Le genre Passalurus est spécifique d'un groupe de Lagomorphes, les Léporidés, dans toute leur aire de répartition; il possède des caractères primitifs qui témoignent d'une parenté avec certains Oxyuridae de Rongeurs et des caractères très spécialisés qui prouvent une adaptation étroite et sans doute ancienne à ses hôtes. ac]19820914

    Notes: Summary Spinicauda voltaensis n.sp. is described from a toad, Bufo sp., from Upper Volta, Africa. It differs from other Spinicauda spp. in the number, distribution and size of caudal papillae in males, in the lack of a gubernaculum, and in the possession of markedly elongate spicules and a relatively short male tail. S. mathevossianae Skarbilovich, 1950, is probably a synonym of Aplectana acuminata (Schrank, 1788) (Cosmocercidae). S. komodoensis Pinnell & Schmidt, 1977, is transferred to Moaciria.

    Notes: Abstract Stephanofilaria thelazioides n. sp. (Filarioidea: Filariidae: Stephanofilariinae) is described from a hippopotamus Hippopotamus amphibius. This nematode is close to S. dinniki Round, 1964, a parasite of the black rhinoceros Diceros bicornis in Africa, but differs from it in the number of cuticular spines surrounding the mouth, the arrangement of the cloacal papillae and the measurements of the spicules, gubernaculum and microfilariae. Species of the genus Stephanofilaria possess spines on the head which have been derived by modification of the sensory papillae. S. thelazioides is the most primitive species of the genus and has the least modified arrangement of these papillae, with six bifid internal labial spines, four bifid external labial spines and four cephalic papillae. The genus appears to have diversified in various mammals which have in common a thick skin, such as rhinoceroses, elephants, buffaloes and now the hippopotamus. It appears to have become adapted secondarily to domestic bovines, initially in Asia and subsequently in North America.

    Description: The filaria Litomosoides sigmodontis, which develops a patent infection in BALB/c mice, was used to determine the fate of a challenge inoculum following immunization of mice with irradiation attenuated infective larvae (3 subcutaneous inoculations at weekly intervals with 25 L3 irradiated at 60 krad, and challenge with 25 L3 two weeks after the final immunization). The adult worm burden of vaccinated mice was reduced to 50% of that of controls although the pattern of larval migration and microfilaraemia were not affected. Necropsies showed that the increased killing of the filariae of the challenge inoculum occurred at the L3 stage within the first 2 days of challenge. This result draws attention on the protective mechanisms operating very early and probably in the subcutaneous region.
