A review of the species-group (Hymenoptera, Formicidae) from Greece.

A review of the Greek members of the species-group revealed three species new to science: (Sterea Ellas, Euboea Island), (Peloponnese, Arcadia) and (Peloponnese, Arcadia and Lakonia). The diagnoses of Salata, Borowiec & Trichas, 2018 and (Dlussky & Zabelin, 1985) are updated based of the new discoveries. Additionally, presence of the latter species in Greece is discussed and its distribution range revised. All members of the species-group are associated with alpine and rocky habitats such as pastures and thermophilous forests. A dichotomous key to the species-group from Greece is given.
