Ants of the Genus Fallomyrma Dlussky et Radchenko (Hymenoptera, Formicidae, Myrmicinae) from Late Eocene European Ambers

Resumo

The extinct monotypic ant genus Fallomyrma was described by Dlussky and Radchenko in 2006 based on workers from Late Eocene Rovno (Ukraine), Scandinavian (Denmark), and Bitterfeld (Germany) ambers. Three new Fallomyrma species from the Rovno amber are here described based on workers: F. anodonta sp. nov., F. marginata sp. nov., and F. robusta sp. nov. A key to all known species of this genus is compiled. The quantity ratios (of the numbers of species and specimens) of Fallomyrma and other amber Myrmicinae genera are considered. The opinion of the autochthonous origin of the Rovno amber is confirmed.
