Two new species, Plagiolepis wheeleri sp. nov. and P. paradoxa sp. nov., are described. A lectotype of Plagiolepis klinsmanni Mayr, 1868 and neotypes of P. kuenowi Mayr, 1868 and P. solitaria Mayr, 1868 are designated. Rhopalomyrmex pygmaeus Mayr, 1868 (= Plagiolepis balticus Dlussky, 1997) is recognized as a new synonym of P. kuenowi Mayr, 1868. A key for identification of the Late Eocene species of Plagiolepis from the European ambers is provided.
