USA. Alaska: Inaru River, 28.vii.1956; ex. dandelion flowers (1 ♀, CNC). Recognition. Mid-sized (wing length 4.2–5 mm), dark-legged, greyish species. Male (Fig. 33) holoptic; scutum densely greyish pruinescent, with two indistinct darker vittae between rows of acr and dc (dorsal view); thorax black setose, upper proepisternum in front of spiracle bare; main mesonotal setae well differentiated, strong, notopleuron with cluster of several long blunt-tipped setae, acr biserial, presutural dc 1–2-serial, 6 sctl; spiracles brown; fore coxa with strong blunt-tipped setae anteriorly; hind tibia evenly thickened toward apex, hind basitarsus slightly thickened, both with similar long, dense fine setae dorsally; wing faintly infuscate, CuA+CuP incomplete, basal costal seta absent, halter with yellowish knob; abdomen faintly greyish pruinescent, with yellowish setae; terminalia with subepandrial lobe, phallus mostly exposed, thickened at base, without loops, evenly curved. Female similar to male, except eyes dichoptic, wing darker infuscate, legs and abdomen with much shorter setation; legs without pennate setae, hind tibia and basitarsus slender. Distribution. Holarctic; in North America this species is known from a few localities along the Beaufort Sea and the Pribilof Islands in the Bering Sea (Sinclair et al . 2019); in Eurasia, it is recorded only from Wrangel Island. Habitat. Almost all specimens of this species were collected in the 2000s in the colder region of Wrangel Island (Neozhidannaya River), in biotopes with different moisture. : 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 page 32, DOI: 10.11646/zootaxa.4848.1.1, http://zenodo.org/record/4406987 : {"references": ["Sinclair, J.
