The ant fauna of Greek Thrace has been least known of all Greek regions with only 12 species mentioned in the literature. We conducted two field trips to this region in 2014 and 2015 and included some unpublished ant material, thus compiling new records from 72 sampling localities.
We found 115 ant species, 108 of them are recorded for the first time in Greek Thrace. Cataglyphis viaticoides, Temnothorax aeolius, Tetramorium cf. davidi, Tetramorium hippocratis, and Tetramorium rhodium were so far not known for continental Greece. In the checklist of recorded species, we also give information on the taxonomic status and distribution of certain taxa.
