Abstract: A new species of the peculiar extinct myrmicine ant genus Enneamerus Mayr is described from Baltic amber (Late Eocene, Priabonian, ca. 34-38 Ma), and a neotype of E. reticulatus Mayr is designated. Enneamerus costatus sp. nov. differs from the previously known E. reticulatus by its much coarser, costulate sculpture on the frons and by the absence of long erect hairs on the antennal scape. Some additional diagnostic features for Enneamerus are provided and the taxonomic position of the genus is discussed.

Keywords: Myrmicinae, fossil, new species, Enneamerus costatus, E. reticulatus, neotype, Late Eocene, Baltic amber, Rovno amber
