ABSTRACT. 198 hoverfly species belonging to 45 genera of three subfamilies were collected from Magadanskaya Oblast. Representatives of the subfamily Microdontinae have not been found in the study area as well as in many other northern regions. Most species were recorded in the subfamily Syrphinae (104 species), followed by Eristalinae (88 species) with a difference of 14 taxa, and the subfamily Pipizinae with 6 species closes the list. At the same time, in terms of the number of generic taxa, Eristalinae is noticeably ahead of Syrphinae, 24 and 19 genera, respectively. The species rich Syrphinae genus Platycheirus Lepeletier et Serville, 1828 includes 30 species, which share 15.7% of the fauna. The genus Cheilosia is the most species rich in the subfamily Eristalinae and includes 13 species. Analysis of species distribution showed that the fauna is formed mainly by widely spread species with multi regional, Holarctic or Trans-Eurasian ranges.
