The extinct ant genus Eocenomyrma was established by Dlussky and Radchenko (2006) and included at that time four species, found in the Late Eocene Baltic, Bitterfeld and Scandinavian ambers (Priabonian stage, 33.9–37.2 Mya): Eocenomyrma orthospina Dlussky et Radchenko, 2006 (type species of the genus), Eocenomyrma elegantula Dlussky et Radchenko, 2006, Eocenomyrma electrina Dlussky et Radchenko, 2006, and Eocenomyrma rugosostriata (Mayr, 1868), though members of this genus are rare in all representative Late Eocene European amber collections (Dlussky, Rasnitsyn, 2009). Recently two more new species of this genus, Eocenomyrma ukrainica and Eocenomyrma breviscapa, were described from the Rovno amber (Radchenko, Dlussky, 2016). (Radchenko & Perkovsky, 2018)
