Polynema (Polynema) antoniae

Polynema (Polynema) antoniae (Soyka, 1950) Fig. 4 Novickyella antoniae Soyka, 1950: 6. Polynema antoniae (Soyka): Trjapitzin 1978: 536. Material examined. China, Xinjiang: • 1 ♀, Tekes, 43°09'19"N, 81°47'23"E, 9.VII.2021, Qin Li et al., sweeping; • 2 ♀♀, Yining, 43°42'03"N, 81°37'50"E, 8.VII.2021, Qin Li et al., sweeping. (All in ICXU). Diagnosis. Female. Body length 880–980 μm (n = 3). Body (Fig. 4 A) dark brown, scape and pedicel yellowish-brown, clava dark brown, petiole yellowish-brown, legs pale brown. Antenna (Fig. 4 B) with scape smooth, clava with six mps. Mesoscutum (Fig. 4 C) smooth. Propodeum (Fig. 4 C) with a short median carina. Forewing (Fig. 4 D) with apical part distinctly broadened, dark discal cilia extending proximally to distinctly beyond stigma. Metacoxa (Fig. 4 E) and petiole in lateral view subequal in length. Ovipositor (Fig. 4 E) slightly exserted from the apex of gaster. Male. Unknown. Hosts. Unknown. Distribution. China (Xinjiang); Austria. Comments. This species was collected in Xinjiang in both a lowland area of the Ili Valley and in the mid-elevation mountainous habitat in Tekes County. The morphology of this species is highly consistent with the type specimen described by Soyka in 1950, thus supporting their conspecificity. Shared characteristics include a predominantly dark brown body color; a similar forewing shape with the middle distinctly broadened and a length ~ 4.3–4.5 × the width; the longest marginal setae reaching ~ 2 / 3 of the maximum wing width; the scape ~ 3 × as long as wide and 1.6 × as long as the pedicel; F 2 being the longest flagellar segment and F 1 the shortest. The ovipositor is clearly exserted. Differences lie in the fact that the original description did not specify the number of sensilla and lacked details on the mesosomal characteristics, whereas the modern description adds several structural features not previously recorded, such as a complete median longitudinal groove on the mesoscutum and a short median carina on the propodeum.
