Revision of rock fossils of Dryinidae and Embolemidae (Hymenoptera: Chrysidoidea) Author Olmi, Massimo Author Rasnitsyn, Alexander P.

Type species: Embolemopsis baissensis Olmi, Rasnitsyn & Guglielmino , n. sp. MALE ( Fig. 1 ): macropterous; dorsal side of head swollen; palpal formula unknown; pronotum not distinctly visible, so that it is not possible to see if it has a strong median longitudinal furrow; forewing with 3 basal cells (CC, BC, SBC) + 1DC and 1SDC enclosed by pigmented veins; stigmal vein forming right angle with pterostigma; tibial spurs unknown. FIGURE 1. Embolemopsis baissensis n. gen. n. sp. (length 2.6 mm). FEMALE: unknown. Remarks : in Embolemopsis n. gen. the forewing has 3 basal cells + 1DC and 1SDC cells enclosed by pigmented veins as in extant and fossil species of Ampulicomorpha Ashmead, 1893 ( Olmi, 1996 ) . Embolemopsis is different from Baissobius Rasnitsyn, 1975 , because in Baissobius 1DC and 1SDC cells are not enclosed by pigmented veins. In addition, the new genus has a stigmal vein forming a rectangular angle with pterostigma. In the extant and fossil Embolemidae the stigmal vein forms always an acute angle with the pterostigma.
