Body and antennal colour largely brown to dark brown except gaster in basal third pale yellow. Occiput with fine striations. Antenna with scape 5× as long as broad, funicular segments all longer than broad and increasing in length towards apex (F1 the shortest segment); clava subequal to F3–F6 ( Fig. 1B). Mesoscutum, scutellum and frenum with fine striations. Fore wing disc near venation bare, medially with a few microtrichia and apically setose; longest marginal seta as long as maximum wing width ( Fig. 1C). Metasoma as long as mesosoma; ovipositor with a narrow basal loop, 1.5–2× as long as metatibia ( Fig. 1D) ( Triapitsyn, 2003; Triapitsyn et al., 2007; Hu & Triapitsyn, 2013).
