Dolerus possilensis Cameron, 1882

Notes.

Dolerus possilensis Cameron, 1882a: 178-179. ♀. Syntypes (assumed). Type locality: Possil Marsh near Glasgow, Scotland. Lectotype ♀ hereby designated, labelled: "B.M. TYPE HYM. 1.573" [printed], " Dolerus possilensis Cam.", "Cameron 96-76. [printed] Possil" [handwritten], "B.M. TYPE HYM. [printed] Dolerus possilensis (Cameron 1882)", " Lectotypus [printed] Dolerus possilensis Cameron, 1882 [handwritten in block letters] M.Heidemaa design. [printed]" [red]. Most of the abdomen missing. Ovipositor preparation apparently lost, but probably figured in Cameron (1882a: plate XIX, fig. 8). BMNH.

Probably a parthenogenetic species: no male has ever been recorded. The only known Fennoscandian record is from Sweden: 1♀ [labelled as Dolerus sp.] “Resarö Waxholm / 6 1915", leg. R. Malaise, NHRS. New to the Swedish fauna.
