Abstract

Representatives of chrysidid wasps are described for the first time from inclusions in Late Cretaceous Burmese amber, Five new genera and new species are described and illustrated: dagger Auricleptes nebulosus gen. et sp. nov., dagger Azanichrum pilosum gen. et sp. nov., dagger Bohartiura glabrata gen. et sp. nov., dagger tBurmasega ammirabilis gen. et sp. nov., and dagger Miracorium tetrafoveolatum gen. et sp. nov. We coded 49 morphological characters for species representing the subfamilies Amiseginae, Loboscelidiinae, Cleptinae and Chrysidinae. The cladistic analysis recovered the following relationships: Cleptinae + ( dagger Auricleptes + (dagger Burmasega + (dagger Miracorium + ((Loboscelidiinae + Amiseginae) + ((dagger Azanichrum + dagger Bohartiura) + (dagger Palaeochrum Krombein + (extant Chrysidinae)))))). In light of the cladistic results, we discuss the implications of characters for the interpretation of phylogenetic relationships within the family, and explore the main morphological changes occurred during the diversification of the chrysidid wasps.
