Tergite 9 with 2 pairs of dark cones, large submedial lobes ( Fig. 8View FIGURE 8 A) and small lateral appendages ( Fig. 8View FIGURE 8 C). Sternal synsclerite deeply emarginate, with specialized appendages ( Fig. 8View FIGURE 8 B).

Discussion. Mycomya fimbriata  is distributed throughout the Holarctic region. It has probably also been reported from India as M. flavithorax  (Brunetti 1912, Edwards 1924). M. flavithorax Brunetti, 1912  was described from Darjeeling though the holotype was not studied here. It is a male in poor condition and possibly deposited in Calcutta (see Väisänen 1996). The female of M. fimbriata  was described by Väisänen (1984: 295, figs. 960–961). Santini (1986) has described the biology of M. fimbriata  in Italy.
