Polynema (Polynema) atrosimile Soyka, 1956 Fig. 5 Polynema atrosimilis Soyka, 1956: 41. Bouček 1977: 122. Material examined. China, Xinjiang: • 2 ♀♀, Gongliu: 43°13'33"N, 82°43'15"E, 10.VII.2021, Qin Li et al., sweeping; • 1 ♀, 43°16'19"N, 82°33'44"E, 10. VII. 2021. Qin Li et al., sweeping; • 1 ♀, Xinyuan, 43°24'12"N, 82°33'45"E, 5.VII.2021. Qin Li et al., sweeping. (All in ICXU). Diagnosis. Female. Body length 790–800 μm (n = 4). Body (Fig. 5 A) dark brown, scape and pedicel yellowish-brown, clava brown; petiole yellowish-brown, legs pale brown. Antenna scape (Fig. 5 B) with indistinct cross-ridges; clava with seven mps. Mesoscutum (Fig. 5 C) with conspicuous reticulate sculpture. Propodeum (Fig. 5 C) with a short median carina. Forewing with longest marginal seta as long as greatest width of wing; dark microtrichia on disc beginning well beyond apex of stigma (Fig. 5 D); Ovipositor (Fig. 5 E) slightly exserted beyond apex of gaster. Male. Unknown. Hosts. Unknown. Distribution. China (Xinjiang); Serbia. Comments. Polynema (Polynema) atrosimile is distributed in both mid-elevation Gongliu (1136 m) and lower-altitude Xinyuan (515 m). This species shares key morphological characteristics with the type species described by Soyka (1956), including: a scape longer than the pedicel; the third flagellomere equal in length to the pedicel; gaster ~ 2 × as long as wide; the longest marginal setae nearly equal to the wing width; and clava ~ 2 × as long as F 6. However, it differs in two critical aspects: the new species exhibits a forewing length-to-width ratio of 5: 1 (vs ~ 4.6: 1 in Soyka’s type specimen) and possesses a shorter mesosoma with a mesosoma-to-gaster ratio of about 0.9 (compared to ~ 0.7 in the latter).
