Abstract
A new wasp of uncertain affinities within the family Diapriidae is described after a single specimen preserved in mid-Cretaceous (Early Cenomanian) amber from France. The possible relationships of the new fossil within the family and related groups are discussed. The fossil was studied using phase contrast X-ray synchrotron imaging, a powerful tool recently used in palaeontology studies. Several other organisms (arthropods, plants remains and microorganisms as well) were also found in the same piece of amber, notably aquatic organisms, which supply informations on the habitat of this specimen. Une guêpe Diapriidae (lnsecta, Hymenoptera) énigmatique de l'ambre crétacé français. Une guêpe d'affinités incertaines au sein des Diapriidae, est décrite à partir d'un spécimen unique préservé dans l'ambre crétacé moyen (Cénomanien basal) de France. Les relations possibles du nouveau fossile au sein de la famille et des groupes proches sont discutées. Le fossile a pu être étudié grâce à l'imagerie par rayonnement X synchrotron en contraste de phase, un outil puissant récemment employé en paléontologie. Plusieurs autres organismes (arthropodes, restes végétaux mais aussi micro-organismes) ont été trouvés dans le même morceau d'ambre, et notamment des organismes aquatiques qui nous fournissent des informations quant à l'habitat de ce specimen.Keywords
