Recognition. This species remains known by the female sex only. Small (wing length of lectotype 3.2 mm) blackish flies ( Fig. 38 ); thorax black setose, upper proepisternum in front of spiracle with 3 short setae; scutum brownish grey pruinescent; main mesonotal setae fine, hardly distinguishable, 4 npl, 6 sctl (4 stronger), presutural dc rather long, 2–3-serial, acr biserial; legs brownish, with simple setae, fore coxa with fine setae anteriorly; wing uniformly brownish infuscate, no distinct basal costal seta, CuA+CuP incomplete, axillary incision right-angled, halter brownish; abdomen dark brown, faintly greyish pruinescent, subshiny (lateral view), with brownish setae (extracted from Shamshev & Sinclair 2018: 313).

Distribution. This species remains known only from Novaya Zemlya. In addition to the type material, Sack (1923: 7) noted a female of R. nordqvistii among his specimens of Empididae collected from Krestovy Island (Novaya Zemlya). However, this record needs verification because the original description of R. nordqvistii is noninformative and Sack never examined the types of this species. Also, Frey (1915: 8) identified as R. nordqvistii several females from the delta of Lena River (Yakutia). At least one specimen of this series is present in ZIN and it belongs to a different species.

Remarks. Shamshev & Sinclair (2018) have already noted that the synonymy of R. eunordquisti with R. nordqvistii is doubtful.
