A list of all 117 hymenopteran species recorded from Rovno amber is presented for the fi rst time. This list includes 50 named species (43 %) known only in Rovno amber fauna. Of the remaining species, 59 (50 %) are recorded also from Baltic amber, 37 (32 %) from Bitterfeld amber, 26 (22 %) from Scandinavian amber as well. Half of the species (50 %) are known on both sides of the Subparathetys (that is, recorded in Baltic amber as well), and another half is recorded only to south of the Subparathetys (from the Rovno, Bitterfeld and Scandinavian amber only). One subfamily, Eucoilinae Thomson, one tribe, Protomicroidini Antropov, and 19 genera (Archaeocercus Simutnik, Archaeogryon Kononova & Simutnik, Astigmaton Kasparyan, Boltonidris Radchenko & Dlussky, Dipriocampe Boucek, Disogmus Forster, Fallomyrma Dlussky & Radchenko, Foveorisus Martynova, Lissonota Khalaim, Pristomyrmex Mayr, Protomicroides Antropov, Pseudidris Kononova, Pseudotelea Kononova, Rovenosa Khalaim, Rovnoecus Antropov, Rovnoeucoila Buffington & Perkovsky, Rovnosoma Simutnik, Sierola Cameron, Trjapitzion Simutnik) are recorded only from south of the Subparathetys. These data provide evidence supporting the previously proposed suggestion on the different origin of four main European sources of succinite. The data mentioned above confirm that the source area of the Rovno amber, contrary to the Baltic amber, had been situated southwards from Subparathetys. Platystasius gracilis Kononova & Simutnik and Oxyserphus obsolescens (Brues) are recorded for the first time respectively from Baltic and Scandinavian amber.
