Scatopsciara (Xenopygina) fratercula ( Vilkamaa & Hippa, 2006) comb. n.

( Fig. 12 D–F)

Literature: Vilkamaa & Hippa (2006): 33, 37, figs 3 C–E, 4 B, 4 D, 4 E, 5 C, 6 D (as Corynoptera ); Mohrig et al. (2013): 183– 184.

Further material (not mentioned in Mohrig et al. (2013): 183–184): 2 males, 30.iv.–11.vi.1994, leg. E. Fuller, Canada, Alberta, Berland River at Hwy 40, 53.42°N, 118.20°W, pine forest, Malaise trap ( PWMP) ; 1 male, 24.vii.1974, leg. P. H. Arnaud, USA, Oregon, Crook County, Cougar Camp ground, Marks Creek ( CAS) .

Comments. The species is characterized by two spines with fused bases in the middle of the inner side of gonostylus and 6 spines on the apex. The inner ventral base of gonocoxites is lobe-like and haired rather long. The short lobes of the two spines at the inner side seem to be intermediate between other species of the paradoxa group and Sc. hastata as well as Sc. paradoxa , which have a long protuberance at inner side.

Distribution. Canada (Alberta, British Colombia); USA (Alaska, Oregon).
