Lambertia uliginosa G. n. Sp. n. (Nematoda, Nothotylenchidae)

Abstract

Nematodes of the family Nothotylenchidae, as outlined by Jairajpuri and Siddiqi (1969) and by Golden (1971), show more affinities to Tylenchidae than to Neotylenchidae. Boleodorus Thorne was already transferred to Psilenchinae, a subfamily of Tylenchidae (Geraert, 1971), and Nothanguina Whitehead was placed in Anguininae (Paramonov, 1970). Lambertia comes close to Tylenchinae by general morphology and by having amphis in the form of longitudinal slits, but differs mainly by the lack of valvae in the median oesophageal bulb. Therefore, it is tentatively placed in Nothotylenchidae, but further study of Tylenchidae - Nothotylenchidae complex may change the taxonomic position of this genus.
