The first sclerodermine flat wasp (Hymenoptera: Bethylidae) from the upper Eocene Rovno amber, Ukraine

Abstract A new extinct bethylid wasp attributable to the subfamily Scleroderminae is described from upper Eocene amber found at the Voronki mine in the Vladimirets District of the northwestern Rovno region, western Ukraine. The distribution of Scleroderminae in tropical and temperate regions is discussed. Three species of Bethylinae, seven species of Epyrinae, and three Pristocerinae have already been described from the same amber-bearing deposits demonstrating the rich diversity of Eocene Bethylidae.
