Taxonomic Notes
Salata & Borowiec (2019): Results presented by Prebus (2017) suggest that the tuberum species group (sensu Cagniant and Espadaler 1997) and unifasciatus species group (sensu Bernard 1967) are paraphyletic. In both cases species groups were defined based on West-Mediterranean taxa. Only two Greek members of the tuberum species group were included in analysis presented by Prebus (2017): Temnothorax nigriceps and Temnothorax unifasciatus and they created a separate cluster. Confirmation, if the tuberum species group as defined by us here is a natural, monophyletic group requires further studies.
