Abstract: We revise the genus Ivanauskiella Ivinskis & Piskunov, 1980. Six new species are described: I. sutteri sp. nov. (Greece: Crete), I. bovis sp. nov. (Morocco), I. nigripunctata sp. nov. (Spain), I. annekristinae sp. nov. (France: Corsica), I. limoniella sp. nov. (Bulgaria, Ukraine, Turkey, Russia), I. albimarginata sp. nov. (Armenia, Iran). Ivanauskiella turkmenica Ivinskis & Piskunov, 1980, sp. restit., is reinstated as a separate species from synonymy with I. psamathias (Meyrick, 1891). Updated distribution records are provided for all ten species recognised in Ivanauskiella. Illustrations of adults, and male and female genitalia are provided, as well as data on the DNA barcode when available.
