 The primitive Mesozoic genera "Andrenelia", "Botsvania", and "Praevania" are only tentatively identified as Evaniidae at present; the first was once separated as family Andreneliidae.Evaniidae seem to have undergone significant evolutionary radiation in the Cretaceous; these taxa were separated as Cretevaniidae, but seem to be a subfamily if anything.The main lineages of extant ensign wasps probably were well separated by the mid-Paleogene.
