RADCHENKO, Sándor Csősz, Annamária SZÁSZ-LEN, Ioan Tăuşan, Klára BENEDEK & Bálint MARKÓ Summary: Genus Myrmica is one of the largest ant genera in Romania with 18 species distributed across the entire country. In the frame of this study we present the distribution data of all Romanian Myrmica species: M. bergi, M. constricta, M. gallienii, M. hellenica, M. lobicornis, M. lonae, M. karavajevi, M. rubra, M. ruginodis, M. rugulosa, M. sabuleti, M. salina, M. scabrinodis, M. schencki, M. slovaca, M. specioides, M. sulcinodis and M. vandeli. Four species are reported for the first time in the Romanian fauna: M. bergi, M. constricta, M. gallienii and M. karavajevi, while the occurrence of several species is probable. These species are listed separately. In addition, a key to the worker caste of Myrmica (with the use of male characters for some species) is provided, including species with likely occurrence in Romania.
