Apoid hymenopterans are well represented in the fossil record, particularly in the mid-Cretaceous amber from northern Myanmar with 37 species and eight families. The fossils from this deposit are providing a glimpse into an astonishingly diverse fauna, including lineages with no counterpart in the present day. In this study, we describe two new genera and six new species of a remarkable new lineage of apoid wasps from Burmese amber: dagger Temnogyna gen. nov., , containing dagger T. elegans sp. nov., , dagger T. multiplex sp. nov., , and dagger T. nyx sp. nov.; dagger Rhabdogyna gen. nov., , containing dagger R. R. festiva sp. nov., , dagger R. R. prima sp. nov. and dagger R. R. elongata sp. nov. These new fossil taxa have distinctive body morphology, particularly in the pattern of forewing venation and a remarkable anterior constriction in the 2nd metasomal segment, which sets them apart from all known apoid lineages. To accommodate these extinct taxa, a new family is introduced, dagger Temnogynidae fam. nov. (type genus dagger Temnogyna gen. nov.). ). Furthermore, the phylogenetic affinities of these new taxa are also discussed, based on the interpretations of the main morphological characters presented in previous studies. We also discuss how the discovery of this new family sheds light on the evolution of apoid wasps during the early Cretaceous. (AU) | |
