Notes: Agosti and Collingwood (1987a) recorded Cardiocondyla nigra for Bulgaria and Turkey (Thrace), and Radchenko (1995b) repeated this record (under the name Cardiocondyla batesii that he considered as a senior synonym of Cardiocondyla nigra ). However, Seifert (2003b) regarded Cardiocondyla batesii and Cardiocondyla nigra as separate species. According to him, the first species is distributed in Iberian Peninsula and NW Africa [ Agosti and Collingwood (1987a) recorded it also for Greece], and the latter - in the Iberian Peninsula, North Africa and Turkey. Most probably, both species have distributions that include Mediterranean areas and are absent from Bulgaria; their occurrence in this country needs confirmation.
