Falsiformicidae are found to belong to Vespoidea s.l. and not to Chrysidoidea because of sexually dimorphic antennae (12-segmented in female and 13-segmented in male) and permanently internalized female tergum 7. Eight described species in three genera are known in the family including five new species (Siccibythus oculatus sp. nov., S. pallidus sp. nov., S. martynovae sp. nov., S. ohmkuhnlei sp. nov., S. paulus sp. nov.) as well as a number of undescribed ones, all from mid-Cretaceous ambers (mostly of Kachin in Myanmar but also of Charente in France and Agapa in North Siberia). Phylogenetic affinities of Falsiformicidae within Vespoidea are left to be clarified, and biology of this family is enigmatic yet.
