Mining flies of the genus Ophiomyia Braschnikov, 1897 occurring in the eastern part of Ukraine and some bordering regions are reviewed. In this paper, twelve species without fasciculus in both females and males, are described and figured, including Ophiomyia adunca Guglya, sp. n. and O. vanyushai Guglya, sp. n. Information on distribution, host plants and bionomics of each species is provided. A key to species of Ophiomyia known to occur in Ukraine is compiled.
