<i>Emplastus biamoensis</i> nom. n., a replacement name for ant (Hymenoptera: Formicidae) from Bol’shaya Svetlovodnaya (Late Eocene of Sikhote-Alin, Russian Far East)
<i>Emplastus biamoensis</i> nom. n. is proposed as replacement name for the female ant <i>Emplastus dubius</i> Dlussky, Rasnitsyn et Perfilieva, 2015 from Late Eocene of Sikhote-Alin, Russian Far East, because of homonymy with <i>E. dubius</i> Dlussky et Putyatina, 2014. Comparison of the renamed species with congeners is updated.
