Metasoma in females dorsoventrally depressed, tapered towards apex.

Material examined. New for Europe / Sweden: Norrbotten, Kiruna kommun, Abisko NP, Bare mountain above tree limit, 900m. a.s.l., N68°21.648', E18°43.245', leg. SMTP, 26.VI.–15.VII.2006. 1♀, at NRM.

Notes. This species was described from the Arctic zone in the Northwest Territories and Greenland (Dasch 1964a) and only a single female has up to now been found in northern Sweden. The description is thus based partly on Dasch’s original description.
