Phylogenetic analysis reveals Archaeovespa affinities with Masarinae in mid-Cretaceous amber wasps, indicating that wasp antennal morphology diversified earlier than anticipated.
Three new species of wasps (Hymenoptera: Vespidae) from mid-Cretaceous Myanmar (Burmese) amber, with club-shaped antennae, are assigned to Archaeovespa gen. nov. and provide morphological information for new phylogenetic analyses of Vespidae. Phylogenetic results suggest that Archaeovespa has more affinities with Masarinae than with Protovespinae and, along with Masarinae, composes the sister clade to Polistinae, Eumeninae, Vespinae and Stenogastrinae. New findings indicate that the antennal morphologies of Vespidae diversified significantly during or before the mid-Cretaceous.
