First records of the subfamilies Bethylinae (Hymenoptera: Bethylidae) and Cleptinae (Hymenoptera: Chrysididae) in Upper Cretaceous amber from France

Two new genera and species of fossil chrysidoid wasps belonging to the families Chrysididae and Bethylidae are described from Charentese (Fouras Bois-Vert and Archingeay) lower Upper Cretaceous amber of France. New taxa include: Sphaerocleptes neraudeaui n. gen. et sp., and Nucifrangibulum carentonensis n. gen. et sp. A new bethylid wasp is also described but left in open nomenclature. These findings are the first records of the subfamilies Cleptinae and Bethylinae in these deposits and time interval. The implications of these discoveries, and the features shared with previously known taxa are discussed.     

First record of the family Scolebythidae (Hymenoptera) in mid-Cretaceous amber from Myanmar

Two new genera and species belonging to the family Scolebythidae are described from mid-Cretaceous amber of Myanmar, Cursoribythus silvestris and Siccibythus musculosus. These taxa are introduced into the current phylogenetic tree of the family, in order to analyze their relationships and observe their impacts on our understanding of the family. The implication of the findings (this is the first record of the family in the Cretaceous amber deposits of Myanmar) are discussed.
