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.

A taxon considered in past years as P. pallescens sensu Radchenko is described as a new species: Plagiolepis perperamus sp. nov. based on material from Eastern Mediterranean. Its morphological separation from P. schmitzii Forel, 1895, the second species characterized by dense gaster setosity, is supported by study on their environmental niches. Plagiolepis pallescens Forel, 1889 is redescribed based on type specimens and material collected from various localities spread within Balkans. Its taxonomical status is clarified and a definition of a \‘pallescens group\’ is improved and supplemented. Plagiolepis maura var. taurica Santschi, 1920 and Plagiolepis maura var. ancyrensis Santschi, 1920 are synonymized with Plagiolepis pallescens Forel, 1889.
