The Strumigenys ant species (Hymenoptera: Formicidae) are poorly studied in Bulgaria due to their small size and cryptic lifestyles. To date, only one species, S. baudueri (Emery, 1875), has been reported from a collecting site in the East Rhodopi Mountains (South Bulgaria). Herein we provide the fi rst records of another two species in Bulgaria: S. argiola (Emery, 1869) (Northeast Bulgaria) and S. tenuipilis Emery, 1915 (South Pirin Mountain). Scanning electron microscope micrographs of both species are also provided.

Three new species of the family Formicidae (Hymenoptera) are recorded for the first time from Bul-
garia: Aphaenogaster festae Emery, 1915 (East Rhodopes), Aphaenogaster radchenkoi Kiran \& Tezcan,
2008 (South Pirin and Struma Valley) and Aphaenogaster subterraneoides Emery, 1881 (North Black Sea
coast, Eastern Rhodopes and Sakar Mt.). The present record of A. radchenkoi is the first for Europe and
the occurrence of A. festae establishes its northern range border in Bulgaria. A list of 23 species recorded
in Bulgaria after publishing its catalogue of ant species in 2010 is presented.
