Spiriverpa lunulata (Zetterstedt) lunulata Zetterstedt (1838: 523 orig. desc.) (Thereva); Irwin and Lyneborg (1981 a: 214 type sp. desig., comb. change, 215:Figs. 72– 78 male terminalia, Fig. 79 ant.), Lyneborg (1989: 24 cat.) (Spiriverpa). Type locality Lapponia Norvegica. Holotype female in NHRS, by monotypy. clausa Frey (1911: 55 orig. desc.) (Thereva, as variety of lunulata); Lyneborg (1989: 24 cat.) (Spiriverpa). Type locality Finland. Syntypes in MZHF. Diagnosis. Like Spiriverpa albiceps and S. argentata in having the male ommatidia smaller ventrally and laterally; halter knob dark reddish brown; inner gonocoxal setae dark reddish brown; ventral apodeme extending to anterior margin of dorsal apodeme (Fig. 41); female common duct subequal or shorter than furca (as in Fig. 9); spermathecal ducts originating from common duct (as in Fig. 9). Like S. argentata in having the male epandrium dorsal view (Fig. 36) not constricted posteriorly, lateral view (Fig. 37) directed posteriorly; the male tergite 8 with setae across posterior margin (Fig. 36); and the inner gonocoxal process (Fig. 39) ending beyond posterior margin of gonocoxite. It differs from S. argentata in having the posterior margin of epandrium not yellow, glossy, glabrous (Fig. 36); and the female abdomen dark reddish brown, glossy with gray pruinescence over tergites 1 and 5–7, across posterior of tergites 2–4, with tergite 8 glossy.
