Male (Fig. 9) holoptic; scutum mostly subshiny (dorsal view); mesonotal setae mostly hair-like, 4–6 strong npl, at least 10 sctl, acr biserial, presutural dc multiserial; legs dark, fore basitarsus distinctly thickened (slightly broader than tibia width at apex), with long setae (except dorsal and ventral face), hind basitarsus usually slightly thickened but often quite slender, with long setae dorsally (more numerous and longer in southern populations); wing infuscate, basal costal seta absent, CuA+CuP reaching wing margin but sometimes weakened on about middle, halter with yellowish knob; abdomen with faintly pruinescent tergites dorsally; segments 6–8 modified, tergite 6 broadened, deeply concave posteriorly, sternite 6 inflated, with dense transverse cluster of strong golden setae, sternite 7 with pair of horn-like projections ventrally. Female legs without pennate setae; wing brownish, broadened. Distribution. Holarctic; in North America, R . albopilosa is widespread across the low arctic, with isolated southern records (Sinclair et al . 2019). In Eurasia, the species occurs in Eastern and Western Siberia (Shamshev 2016). Among the Russian Arctic islands, R . albopilosa is known only from Wrangel Island. Habitat. On Wrangel Island this species is found in various biotopes. : 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 16-17, DOI: 10.11646/zootaxa.4848.1.1, http://zenodo.org/record/4406987 : {"references": ["Coquillett, D.
