New Records of Upper Eocene Chrysidoid Wasps (Hymenoptera: Chrysidoidea) from Basins of Styr and Stokhod Rivers (Rovno Amber)

Three species of chrysidoid wasps, Palaeobethylus longicollis (Chrysididae), Dryinus wunderlichi and D. reifi (Dryinidae) are recorded for the first time for Rovno amber from the basin of Styr River (Voronki), and one species, Palaeoanteon janzeni (Dryinidae), is recorded for the first time for Rovno amber from the basin of Stokhod River (Kukhotskaya Volya). Taking into account the new records of chrysidoid wasps and myrmiciine ants, a total of 64 species of Rovno hymenopterans (52%) are registered at Baltic amber. All known fossil records of the wasps in the superfamily Chrysidoidea are listed.
