Three species of Hilara Meigen, described by L.Oldenberg in 1916 (H. caerulescens, H. coracina, H. perversa), are redescribed and the lectotypes are designated. Hilara borealis Oldenberg (new name proposed by Oldenberg for the alpine Hilara czernyi Strobl, 1910, not Strobl, 1909) is shown to be a taxon comprising two geographically different populations, that from northern Fennoscandia is described as new to science, Hilara lapponica sp.n. The main differential features of all species are illustrated. Epigamic behaviour and swarming activity is described for H. borealis.
