A total of 408 species of Syrphidae have been reliably registered in Ukraine, as well as another 30-50 taxa, the records of which have not been confirmed by modern material. The Ukrainian hoverfly fauna has one endemic (Merodon dzhalitae Paramonov, 1926: the Crimean Peninsula) and two subendemic species with narrow ranges (Merodon alexandri Popov, 2010: Ukraine and adjacent Russian regions; Paragus medea Stănescu, 1991: Hungary, Romania, Ukraine). At the same time, some species, such as Chalcosyrphus jacobsoni (Stackelberg, 1921), which have traditionally been considered present in Ukraine, are not confirmed by any old or new material. We highlight the view that national lists should be backed up by reference material for all the species. For some taxa, the publishing years of the first descriptions (namely Paramonov's papers) are still incorrectly cited. A number of taxa have the type locations in Ukraine: Chalcosyrphus obscurus (Szilády, 1939), Zakarpattia Region; Eumerus tauricus Stackelberg, 1952, the Crimea; Merodon crassifemoris Paramonov, 1926 (sic!), the Crimea; etc. In Ukraine, some species have a westernmost frontier in Europe, such as Helophilus continuus Loew, 1854 (also found in Romania and Belarus), Mallota eurasiatica Stackelberg, 1950, etc. Here is the southern borderline of the range for the Eastern European Melanogaster jaroslavensis (Stackelberg, 1922), etc. Finally, it is in Ukraine that the largest populations of the Pseudopelecocera latifrons (Loew, 1856) survive.
