Further Data on the Extinct Ant Genus Eocenomyrma (Hymenoptera, Formicidae)

sp. n. and sp. n., two new ant species of the extinct genus Dlussky et Radchenko, are described from the Rovno amber (Late Eocene, Priabonian, 34–38 Ma). (described based on the male and gyne) differs from the previously known species of this genus by the shorter propodeal spines and by the sculpture of the head and mesosoma. is described based on the single worker and differs from all known species by the punctated head, mesosoma and waist, by another shape of the petiole, by the shorter propodeal spines, and by the distinctly shorter antennal scape. Additional data on the record of (Mayr) and Dlussky et Radchenko is provided. A key for the identification of six known species is compiled. The character of the forewing venation of the male and gyne of supports our idea about relation of this genus and the genus Mayr, and placing to the tribe Formicoxenini.
