Diagnosis. The long slender antenna, uniform dark brown coloration, and rounder wing with shorter R-M vein fusion ( Fig. 4D View FIGURE 4 ) easily distinguishes this species from the other members of the genus ( Fig. 2D View FIGURE 2 ). The long slender apical projection of the gonocoxites ( Figs 8A, C View FIGURE 8 ) is shared only with U. galdes , sp. n. but most other structures of the male terminalia are unique and distinct, including the large spoon shaped projection laterally from tergite IX with a dense brush of long setae internally ( Fig. 8A View FIGURE 8 ). The female can be separated from U. trivittata and U. dorsalis by the short, truncated abdomen ( Fig. 3B View FIGURE 3 ) and by having globular spermathecae with thin inner walls and thin ducts ( Figs. 11E View FIGURE 11 ).

Description. Male (n=5). Body length 6.5–8.5, 7.79 (n=7) mm. Wing length 5–6.72. 5.83 mm, or 3.74–4.15, 3.89 as long as profemur. Antenna length 2.84–3.9 (n=4) mm. Coloration (specimen in alcohol, Fig. 2D View FIGURE 2 ). Head dark brown, mouth parts brown. Antenna brown with basal part of first flagellomere pale. Thorax dark brown; thoracic stripes dark brown, diffusely separated; humeral area brown. Wings clear, yellow tinged, veins paler brown than in other species. Halter whitish. Legs brown. Abdomen uniformly dark brown. Terminalia ( Fig. 8 View FIGURE 8 ). Gonocoxites divided ventrally, with long slender projection. Hypandrial lobe tongue shaped and curved dorsally. Double "bladder shaped" aedeagal guides situated above the gonocoxite. Gonostylus long and slender, subrectangular in lateral view with the apicodorsal corner slightly elongated. Aedeagal apparatus short and small compared to other species, with compressed plate extending only slightly beyond apex of the stout and short lateral apodeme. Tergite IX with large spoon shaped projection laterally and with large dense brush of long setae internally, with deep posterior and shallow anterior U-shaped incision. Proctiger small and short, cercus sessile, broadly ovate in lateral view.

Female (n=3). Body length 5–5.5 mm. Wing length 4.04–4.08 mm, or 3.29–3.54 as long as profemur. Antenna length 1.62–1.7 mm. Coloration. Overall brown as in male ( Fig. 3B View FIGURE 3 ). Terminalia ( Fig. 11E–F View FIGURE 11 ). Tergites VIII and IX weakly sclerotized apically in front of cercus. Cercus sessile and ovate. Sternite VIII divided ventrally, with slightly truncated corner, with a narrow excavation apicomedially covered with short stiff setae. Spermathecae globular, spermathecae and ducts with thin inner walls.

Distribution. Western Europe; known only from northern Britain ( Scotland and northern England), France, Norway, Sweden and The Netherlands.
