General distribution. Eastern Austria, Bulgaria, Croatia, Greece: Macedonia, North Aegean Islands, Sterea Ellas, Peloponnese, and Thessaly, Hungary, Slovakia, western Turkey. Comment. We examined a syntype of Temnothorax tauricus (Ruzsky, 1902) preserved in Forel's collection (MHNG) and it appears to be very similar to specimens of T. turcicus collected in Greece. The only difference is a slightly darkened antennal club in the syntype specimen of T. tauricus (all studied specimens of T. turcicus have antennae uniformly yellow). We discussed this issue with Alex Radchenko (Kiev, Ukraine) who confirmed that all 17 syntypes of T. tauricus preserved in Karavaiev's collection (Kiev, Ukraine) also have slightly darkened antennal club. In our opinion this difference could be an infraspecific variation. Within nest samples of Temnothorax messiniaensis , a member of the aveli species group, we observed single specimens with more or less darkened antennal club. Temnothorax tauricus was recorded from Caucasus and southern Ukraine but is sympatric with T. turcicus in Bulgaria and Greece. Temnothorax tauricus have nests in dry stems of herbs, grasses or rarely in soil under stones ( Radchenko 2016 ) and by those preferences reminds species of the T. aveli species group. Clarification of taxonomic relation between those two taxa requires further study based on material collected from the whole distribution range of both species. If our supposition on the conspecifity of both taxa is confirmed, then the name T. tauricus will have priority over the name T. turcicus . Biology. Specimens collected on shadow localities, from seacoast to 1000 m a.s.l. Foraging workers were observed on herbs in stream valley of tourist resort, valleys with Platanus trees, mountain coniferous forest and mountain pastures close to border of coniferous forest. Nests were not found, probably like other species of this group, are located inside dry stems of herbs. The following ant species were recorded in the same areas as T. turcicus : For localities on Macedonia : Pieria, road to P. Poroi loc. 1, Pieria, road to P. Poroi loc. 2, Pieria, road to P.
