Recognition. Mid-sized (wing length 5.4–6.1) blackish slender flies. Male (Fig. 39) holoptic; scutum faintly greyish pruinescent, with 4 narrow shiny vittae; presutural dc pale 1–2-serial, hair-like, moderately long, acr biserial, similar to but somewhat shorter than dc, laterotergite with pale setae; legs long, very slender, shiny, with strongly reduced setation; hind tibia gently curved inwards beyond middle, hind basitarsus long spindle-shaped, with dense long hair-like setae dorsally; wing faintly infuscate, CuA+CuP almost complete, well sclerotized, disappearing or evanescent just before wing margin, halter yellow; abdomen with shiny dorsum, covered with pale setae; terminalia longer than thorax; epandrium elongate, almost strap-like, somewhat broadly constricted on about middle, with broadly rounded apex; cercus long, but shorter than epandrium, narrow, constricted on about middle; phallus very long, hair-like, without loops, extended beyond epandrium. Female (Fig. 40) wing broad, brownish; hind tibia and tarsus simple; legs without pennate setae. Distribution. Holarctic; R . septentrionalis occurs in the low arctic west of Hudson Bay of North America and in northern regions of Russia (Sinclair et al . 2019). Habitat.
