Material examined. CHINA, XINJIANG, Jimsar Co., Dalongkou , 43°54'13''N 89°10'12''E, 1008 m, 14.vi.2015, on poplar ( Populus sp.) infested with idiocerine leafhoppers: H.-y. Hu group [6 ♀, ICXU] ; S.V. Triapitsyn [8 ♀, UCRC].

Redescription. FEMALE. Body length 1230–1370 µm. Body darkish brown to black.

Antenna ( Fig. 19 ) with radicle about 0.3× total length of scape, rest of scape 2.0–2.4× as long as wide; pedicel longer than F1; F1 the shortest funicle segment, F3 a little longer than F2 or F4, F5 the longest funicle segment, following funicle segments usually progressively slightly shorter than preceding ones; mps on F5 and F6 (1 each), F7 and F8 (2 each); clava with 8 mps, 2.4–3.7× as long as wide.

Mesosoma shorter than metasoma. Propodeum ( Fig. 20 ) with fine, subparallel submedian carinae close to each other and usually not extending to anterior margin. Fore wing ( Fig. 21 ) about 2.8× as long as wide; longest marginal seta about 0.2× maximum wing width; disc almost hyaline, bare behind venation except for 2 setae just behind stigmal vein. Hind wing 12.5–15.3× as long as wide; disc almost hyaline; longest marginal seta 1.4–2.0× maximum wing width.

Ovipositor ( Fig. 22 ) long, occupying entire length of gaster and markedly exserted beyond its apex, 2.9–3.3× as long as mesotibia.

MALE. Unknown from China.

Distribution. Holarctic ( Triapitsyn 2013a) including China (new record, known only from its Palearctic part).

Hosts. Idiocerine leafhoppers ( Cicadellidae ) listed by Triapitsyn (2013a); unknown in China.
