Male (Fig. 13) holoptic; thorax black setose, scutum densely brownish grey pruinescent, with dark vittae beneath acrostichal and dorsocentral rows; mesonotal setae mostly fine, long, presutural dc and acr multiserial; legs robust, entirely dark brown, hind femur without setae on about apical 2/3 ventrally, only densely pale pilose, hind tibia evenly thickened toward apex; wing brownish infuscate, halter yellowish; cerci directed anteriorly, very long, extended nearly to middle of abdominal tergite 3, epandrium dark. Female wing broadened; legs without pennate setae. Distribution. A Holarctic species with huge area of distribution; in Eurasia, R. nigrita is widespread across the low and high arctic of Norway, Sweden and Russia (with some records from the boreal zone; e.g ., Altay, Magadanskaya Province); in North America, from Greenland to Alaska and as far south as Churchill, Manitoba and northern British Columbia (Sinclair et al . 2019). However, among the Russia Arctic islands, R . nigrita was found only from Wrangel Island. Habitat. On Wrangel Island this species is most common in the warmer central region of the island, where it is found in various biotopes. In colder areas (Neozhidannaya River, coastal plain in Somnitelnaya Bay), a single specimen was found. : 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 26-27, DOI: 10.11646/zootaxa.4848.1.1, http://zenodo.org/record/4406987 : {"references": ["Zetterstedt, J.
