Hypopygium ( Fig. 12 View FIGURES 8–12 ). Tergite IX with 11–18 setae (from one side) and with anal point 62–78 μm long, which in distal half slender and hair-like. Laterosternite IX with 5–8 setae. Transverse sternapodeme like narrow arch, 170–180 μm long. Gonocoxite 250–280 μm long, with broad basal lobe and lobe-like medial field, covered with 6–9 setae 24–32 μm long. Gonostylus 110–140 μm long, with long and rounded apically crista dorsalis; macroseta 8–9 μm long. HR 2.00–2.28.

Comments. After comparing the male hypopygium and DNA analysis data of the Pseudokiefferiella sp. from Vaigach Island and the Pseudokiefferiella sp. from Northern Norway (BOLD ID: CHRFI378, BIN BOLD:AAV2899) we came to the conclusion that this is the same and apparently new to science species. However, we believe that in order to fully confirm this it is necessary to conduct an additional revision of the known species of this genus shown in Figure 17 View FIGURE 17 . It is also necessary to determine which of them is really the Pseudokiefferiella parva (Edwards) .
