ABSTRACT. A new genus, Vorstadt gen.n., is described from Late Eocene Baltic amber. It includes V. ambermuseum sp.n. (type species) and V. groehni (Tolkanitz et Perkovsky, 2015). Progressive oligomerization of flagellomeres in the Hybrizoninae apparently occurred by pairwise fusion. The genus Vorstadt gen.n. is likely to occupy an intermediate position between the members of the subfamily with polymerous and oligomerous flagella, i.e., the fossil genus Ghilarovites Kasparyan, 1988 as well as Tobiasites Kasparyan, 1988, Paxylommites Kasparyan, 1988 and recent genera respectively. A key on Hybrizoninae of the Baltic amber is given.
KEY WORDS: Baltic amber, palaeoentomology, Late Eocene, ant parasitoid, Ichneumonidae.
