title: [Neoparasitylenchus megabothridis n. sp. (Tylenchida: Allantonematidae) parasite of Megabothris tubidus (Siphonaptera: Ceratophyllidae); observations on fleas tylenchides in the S.W. of Europa (author's transl)].
abstract: A number of nematodes (Tylenchida, Allantonematidae) were observed in 11 species of Siphonaptera from the South-West of Europe. The fleas belong of 4 differents families (Pulicidae, Vermipsyllidae,Hystrichopsyllidae, Ceratophyllidae). Neoparasitylenchus megabothridis n. sp., parasite of the flea Megabothris turbidus (Rothschild, 1909), is described and the life cycle given. It shows little pathogenicity to tis host. Psyllotylenchus sp. parasite of Nosopsyllus fasciatus (Bosc, 1801), appears to be a teratogenic and causes a feminisation of parasitised males and a masculinisation of females. A generic determination cannot be made with any certainty in the material collected from others fleas.
