Two new genera of cuckoo wasps (Chrysididae: Amiseginae) from Rovno and Baltic ambers

Cuckoo wasps of the subfamily Amiseginae, Eosega heterotarsata gen. et sp. nov. and Foveorisus kilimniki gen. et sp. nov., from the Late Eocene Baltic (Russia) and Rovno ambers (Ukraine), respectively, are described. Primitive Eosega is close to the extinct genus Palaeobethylus Brues in Kieffer, 1914 and represents the so-called American series of genera of Amiseginae. Foveorisus is found to be morphologically close to a number of extant oriental genera. All known fossil Amiseginae are listed. Stick insects of the family Archipseudophasmatidae, possible hosts of the Eocene amisegines, are recorded in the Rovno amber for the first time.
