Abstract Species of the subgenus Symplecta Meigen with Arctic, or at least partly Arctic, distributions are revised. Five species are redescribed: S. ( S. ) novaezemblae (Alexander), S. ( S. ) scotica (Edwards), S. ( S. ) mabelana (Alexander), S. ( S. ) sheldoni (Alexander), and S. ( S. ) horrida (Lackschewitz). Two new species are described: S. ( S. ) edlundae sp. nov. (Northwest Territories and Yukon, Canada) and S. ( S. ) echinata sp. nov. (eastern Siberia, Russia). Five new synonyms are proposed: Erioptera ( S. ) sunwapta Alexander and Helobia intermedia Lackschewitz = S. ( S. ) scotica Erioptera ( S. ) platymera Alexander = S. ( S. ) mabelana S. ( S. ) rotundiloba Podenas and Gelhaus = S. ( S. ) sheldoni and Erioptera ( Psiloconopa ) chaetophora Alexander = S. ( S. ) horrida . Symplecta ( Symplecta ) scotica and S. ( S. ) mabelana are restored as full species from subspecies rank. Symplecta ( Symplecta ) horrida , previously placed in Erioptera ( Mesocyphona ) Osten Sacken, is transferred to Symplecta s.s . The distinctions between S. ( S. ) cana (Walker) and S. ( S. ) hybrida (Meigen) are clarified and the sympatric and syntopic occurrences of these species are documented. A key to the species treated, and illustrations of both male and female terminalia, are provided and the distribution of each species is outlined.
