Messor hellenius

This species is known from Greece, the western coast of Anatolia and the European part of Turkey (Salata and Borowiec 2019a, Kiran and Karaman 2020). Borowiec and Salata (2018) suggested that the previous records of Messor capitatus from eastern parts of the Balkan Peninsula concern M. hellenius. In this regard, it is very likely that the data on M. capitatus from the northern Black Sea coast (Markó and Csősz 2002) refer to M. hellenius. Specimens from the vicinity of the Medenbuk and Golyam Dervent villages have intermediate characteristics between Messor mcarthuri and M. hellenius, which may indicate a possible hybridisation between these species (Lapeva-Gjonova & Borowiec, 2022).
