ABSTRACT. The species composition and distribution of the shore-flies of the genus Ephydra Fallén, 1810 (Diptera, Ephydridae) of the fauna of Russia are completely revised for the first time. In total, 9 species were found: E. afghanica Dahl, 1961, E. attica Becker, 1896, E. glauca Meigen, 1830, E. japonica Miyagi, 1966, E. macellaria Egger, 1862, E. pseudomurina Krivosheina, 1983, E. riparia Fallén, 1813, E. scholtzi Becker, 1896, and one new species, E. villosa sp.n. The new species belongs to the glauca species group and differs from E.glauca in the number of intra-alar setae and inwardly curved surstyli covered with long setae. It was found in Irkutsk Oblast. The data on the distribution of Ephydra species on the territory of Russia and the Palearctic Region are updated. E. attica is recorded from Kazakhstan, Uzbekistan, Tajikistan, Turkey and Morocco for the first time; E. glauca is newly recorded from Ukraine, Kazakhstan and Uzbekistan; likewise, the following represent new country records, E. macellaria for Kyrgyzstan, Tajikistan and Mongolia; E. pseudomurina for Ukraine, Azerbaijan, Georgia, Kazakhstan and Tajikistan; E. riparia for Kazakhstan and E. scholtzi for Tajikistan. A key to species found on the territory of Russia is compiled.
