M. Langourov. Detailed occurrence data: Lapeva-Gjonova and Borowiec (2022) . Notes First record for Bulgaria. Temnothorax rogeri is an eastern Mediterranean species, known from Croatia, Greece, Montenegro and Turkish Thrace ( Borowiec and Salata 2018 , Kiran and Karaman 2020 ). Recently, it was recorded in Slovakia, but most likely this record is based on an introduced specimen ( Klesniakova et al. 2018 ). Morphologically, it is very close to T. recedens (Nylander, 1856), which is known from the southern regions and the Black Sea coast in Bulgaria ( Atanassov and Dlussky 1992 , Lapeva-Gjonova et al. 2010 ).
