Abstract

Electronoyesella antiqua Simutnik, gen. et sp. nov., is described and illustrated based on a female specimen from late Eocene Rovno amber. Like most previously described Eocene Encyrtidae, the new taxon differs from the majority of extant ones in a number of features. Sclerotised metasomal structures, similar to the paratergites of extant Tetracneminae, are seen here for the first time in fossils. The new genus is characterized also by the frontovertex with four vertical rows of piliferous punctures and the face also with intricate sculpture; notauli are present as small but distinct depressions, only anteriorly; the apex of metatibia with a peg originating from a round, deep pit; and the unusual setation of the hind wing.
