Polynema (Polynema) pusillum Haliday: Triapitsyn and Fidalgo 2006: 61; Schuppenhauer and Triapitsyn 2018: 168, 170–171. Material examined. China, Xinjiang: • 1 ♀, Huocheng, 43°56'41"N, 80°52'13"E, 5.VII.2021, Qin Li et al., sweeping; • 1 ♀, Qinhe, 46°26'05"N, 90°02'45"E, 9.VII.2020, Qin Li et al., sweeping; • 1 ♀, Tacheng, 46°36'34"N, 82°57'59"E, 29.VI.2021, Qin Li et al., sweeping. (All in ICXU). Diagnosis. Female. Body length 710–800 μm (n = 3). Body (Fig. 14 A) dark brown, scape and pedicel yellow, F 1 – F 5 pale yellow, F 6 and clava brown; petiole and legs yellow. Antenna (Fig. 14 B) with scape smooth, 2.5–2.7 × as long as wide (including short radicle); F 4 and F 5 subequal in length; clava as long as combined length of three preceding flagellomeres, with seven mps. Mesoscutum (Fig. 14 C) with indistinct reticulate sculpture. Metacoxa (Fig. 14 E) in lateral view 1.1–1.2 × as long as petiole. Male. Unknown. Hosts. Unknown. Distribution. China (Xinjiang); Europe and Turkey. Comments. The specimens from Xinjiang share similarities with the European specimens of P. pusillum, as redescribed by Schuppenhauer and Triapitsyn (2018), in having a short median carina on the propodeum and the longest marginal setae on the forewing are ~ 0.7 × the wing width. However, they differ in that the scape of the Xinjiang specimens is smooth, whereas the scape of the European P. pusillum has some faint longitudinal striations.
