ABSTRACT. Molecular-genetic study of blues Polyommatus fominae Stradomsky, 2005 and P. szabokyi Bálint, 1990 showed that they have the mitochondrial gene COI characteristic of P. icadius (Groum-Grshimaпlo, 1890). The nuclear gene ITS2 of all the studied P. fominae is identical to that of P. icarus (Rottemburg, 1775), the ITS2 in one specimen of P. szabokyi was characteristic of P. icarus, and in the other — to P. icadius. Basing on the external characters and the molecular-genetic data, it is supposed that the taxa P. fominae and P. szabokyi appeared as a result of hybridization of P. icarus and P. icadius.
