The phylogenetic relationships and natural classificition of the Vespoidea (Hymenptera)

Abstract. Phylogenetic relationships of the subfamilies and tribes of the Vespoidea (= Diploptera) are investigated using cladistic methods. A natural classification is proposed, sequencing seven tribes in six subfamilies within the single family Vespidae. Euparagia is the sister‐group of the rest of the Vespidae. The Gayellinae and Masarinae are sister‐groups, and are reduced in rank to tribes within the subfamily Masarinae. This is the sister‐group of the Eumeninae + Stenogastrinae + Polistinae + Vespinae. The Zethinae is a paraphyletic group; both it and the Raphiglossinae are deleted and included in the Eumeninae. The Stenogastrinae is regarded as the sister‐group of the Vespinae + Polistinae.
