Material examined. RUSSIA. Murmanskaya Prov. (Kildin Island): Kola Bay, 23.viii.–1.ix.1923, Serebrjansky (1 ♂, ZIN). Nenets AO (Kolguev Island) : Bugrino, sea shore, meadow, 21–22.viii.1970, KBG (3 ♂, 2 ♀, ZIN). Recognition. Mid-sized (wing length 5–6.5 mm) greyish, dark-legged, black setose flies. Male (Fig. 54): holoptic; antennal postpedicel and stylus black, scape and pedicel somewhat paler; labrum 1.1–1.5X longer than head height; palpus black, long, with several long strong setae. Thorax grey pruinose, scutum somewhat finer pruinescent, without vittae; prosternum bare, upper proepisternum in front of spiracle with a few fine setae; mesonotal setae strong bristle-like (including acr and dc), acr biserial, presutural dc 2–3-serial, 4–6 sctl; legs blackish brown, long, slender, mostly shiny to subshiny (except coxae); fore femur with single row of very long posteroventral setae; hind femur with 3–4 anterodorsal setae on about apical half, 3–6 strong anteroventral setae of different lengths over entire femur length and 1 long strong posteroventral seta on about basal third; all tibiae with rows of numerous very long strong setae dorsally, hind tibia with 1 long seta in posteroapical comb; fore basitarsus with several long setae dorsally. Wing hyaline, CuA+CuP (anal vein) complete, entirely sclerotized, 1 long basal costal seta present, axillary incision very acute, halter brown. Abdomen (except terminalia) densely uniformly light grey pruinescent, tergites with very long posteromarginal setae laterally; segment 7 with unmodified structure and vestiture; segment 8 with tergite and sternite separated; tergite 8 upturned posteriorly, with slightly convex posterior margin, without projections; sternite 8 nearly as long as sternite 7. Terminalia with cerci and epandrium brownish to reddish brown, faintly pruinescent; cerci separated from each other and from epandrium, not extended anteriorly beyond tergite 8; cercus slightly produced anteriorly, prolonged slightly beyond epandrium middle posteriorly, with narrow cavity near base dorsally forming short finger-like basal projection, rather trapezoid-like beyond cavity, lower posterior corner slightly produced downward, mostly covered with minute setulae, lower posterior corner with dense spinules, without pair of subepandrial lobes beneath; epandrium subtriangular, narrow, rounded apically, with long to moderately long setae more numerous along lower margin; subepandrial sclerite divided; hypandrium yellow, shiny, subtriangular, bare; phallus thick, vesicular apically; ejaculatory apodeme extended far beyond basal curvature of phallus, without lateral wings. Female: similar to male except, eyes dichoptic, frons very broad, parallel-sided; femora mostly with short setulae, only hind femur with 2–4 strong anteroventral setae; wing faintly brownish infuscate; abdominal tergites 5–8 and sternites with shorter setation. Distribution. Palaearctic; Fennoscandia, Great Britain, mountains of Central Europe, across northern Russia from Murmanskaya Province to Taymyr Peninsula. : Published as part of Shamshev, Igor V., Sinclair, Bradley J. & Khruleva, Olga A., 2020, The empidoid flies (Diptera: Empidoidea, exclusive of Dolichopodidae) of the Russian Arctic islands and Svalbard Archipelago, pp. 1-75 in Zootaxa 4848 (1) on pages 49-50, DOI: 10.11646/zootaxa.4848.1.1, http://zenodo.org/record/4406987 : {"references": ["Zetterstedt, J.
