Distribution of the Dolichopus planitarsis species group. Most species of the D. planitarsis species group occur in the northern part of the Palearctic Region. Nevertheless, D. planitarsis itself is widespread from Western Europe across Central Europe and boreal Russia to Kamchatka. Dolichopus annulitarsis is widely distributed in subarctic areas from Scandinavia across Russia to Alaska. Dolichopus bonsdorffi is known from North Europe, Russian Far East and north-eastern China. The other species of the group are rarely collected, but are also apparently broadly distributed in the arctoboreal belt of Eurasia. Dolichopus tundrensis is only known from the high-mountain tundra in Altai Mountains. It seems that this group is absent in the Nearctic Region (except D. annulitarsis) and Orient (Van Duzee & Curran 1934; Steyskal 1973; Zhang & Yang 2008). Afrotropical D. afroungulatus Grichanov, 2004, has rather similar ornamentation of mid tarsus, but differs from the D. planitarsis species group in many other respects, especially in morphology of face, wing, and hypopygium, belonging apparently to a different group of species (Grichanov 2004).
