Carebara oertzeni Forel is recorded from the European part of Turkey for the first time based on queens, a male, and workers. The hitherto unknown worker caste of C. oertzeni is recorded and described for the first time. Our queen and male specimens have some differences from the typical C. oertzeni specimens. The differences are the sculpture on the anterior half of head, on the pronotum, and the area between the metanotal teeth, larger head measurements and some body ratios in queen; head measurements, 4-toothed mandibles, scape measurements, ratio of scape and 2nd funicular segment, and hair density on head dorsum in male. Moreover, some biological notes for the species are given.
