New Ichneumonidae (Hymenoptera) from the Upper Cretaceous ambers of the Taimyr Peninsula

Two new genera and four new species of Ichneumonidae are described from the Upper Cretaceous ambers of the Taimyr Peninsula: Agapia sukatchevae gen. et sp. nov., Agapteron popovi gen. et sp. nov., Eubaeus abdominalis sp. nov., and Urotryphon baikurensis sp. nov. New detailed diagnoses are provided for the genera Urotryphon and Eubaeus. The genera Catachora, Urotryphon, and Eubaeus, previously placed in the subfamily Tryphoninae, are transferred to the subfamily Labenopimplinae, as well as the new genera Agapia and Agapteron. Possible causes of the miniaturization in ichneumonid wasps in the Cretaceous are discussed.
