| Abstract: | The first definitive Burmese amber fossil of the family Gasteruptiidae s.str. (Evanioidea) is described and figured from a male entombed in amber from the Hukawng Valley, Myanmar. The Cenomanian-aged fossil is plesiomorphic in many respects when compared to the modern subfamilies Hyptiogastrinae and Gasteruptiinae. The genus Hypselogastrion Engel, gen. nov. (type species: Hypselogastrion simplex Engel and Wang, sp. nov.), is segregated into the extinct subfamily Hypselogastriinae Engel, subfam. nov., owing the more enriched wing venation, aulcid-like mesoscutal sculpturing, non-clavate metatibia, and absence of U-shaped notauli. The affinities of H. simplex among other living and fossil Aulaciformes are discussed. |
