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.) edlundaesp. nov. (Northwest Territories and Yukon, Canada) and S. (S.) echinatasp. 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.

Résumé

Nous révisons les espèces de Symplecta s.s. trouvées particulièrement dans l’Arctique. Cinq espèces sont décrites à nouveau: S. (S.) novaezemblae (Alexander), S. (S.) scotica (Edwards), S. (S.) mabelana (Alexander), S. (S.) sheldoni (Alexander) et S. (S.) horrida (Lackschewitz). Deux nouvelles espèces sont proposées et décrites: S. (S.) edlundaesp. nov. (Territoires du Nord-Ouest et Yukon, Canada) et S. (S.) echinatasp. nov. (Sibérie Est, Russie). Cinq synonymes sont proposés: Erioptera (S.) sunwapta Alexander et Helobia intermedia Lackschewitz = S. (S.) scotica; Erioptera (S.) platymera Alexander = S. (S.) mabelana; S. (S.) rotundiloba Podenas et Gelhaus = S. (S.) sheldoni; Erioptera (Psiloconopa) chaetophora Alexander = S. (S.) horrida. Les deux espèces S. (S.) scotica et S. (S.) mabelana sont rétablies au rang de sous-espèces. Symplecta (Symplecta) horrida est transferée d’Erioptera (Mesocyphona) Osten Sacken et placée dans Symplecta s.s. Nous clarifions aussi les répartitions géographiques et les distinctions entre S. (S.) cana (Walker) et S. (S.) hybrida (Meigen), et nous présentons les occurrences sympatrique et syntopique des deux espèces. Une clef d’identification ainsi que des illustrations des génitalia mâles et femelles sont présentées et les nouvelles répartitions géographique sont données.
