Recognition. Mid-sized(wing length 4.8–5.4mm)blackish brown species.Male(Fig. 32) holoptic; anepisternum densely pruinescent, scutum densely brownish pruinescent, presutural dc multiserial, long, acr similar but 2–3- serial; legs robust, dark brown, no modified podomeres, hind femur with short spine-like setae ventrally, all tibiae with several long bristle-like ad and pd setae, mid basitarsus with 1 long dorsal seta on about middle; wing faintly infuscate, CuA+CuP incomplete, halter brown; abdomen densely brownish pruinescent, black setose; epandrium elongate, narrow, constricted in middle, projecting far beyond cercus; cercus V-shaped, strongly constricted in middle; phallus well-exposed, filamentous, very long, without loops, gently curved beyond apex of epandrium. Female: anal lobe of wing darker than wing tip, legs without pennate setae. Distribution. Holarctic; in North America, R. filicauda occurs across the low and high arctic from Greenland to Yukon (Sinclair et al . 2019); in Eurasia, it is known only from Wrangel Island. Habitat. A large series of this species was collected only once (in 1966) in the warmer central region of the island, in dry spotted tundra. In the 2000s, all collections of this species were also limited by dry biotopes of this part of the island. : 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 31-32, DOI: 10.11646/zootaxa.4848.1.1, http://zenodo.org/record/4406987 : {"references": ["Sinclair, J.
