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.
