Redescription. FEMALE. Body length 1059–1400 µm. General body color black; antenna dark brown; legs yellowish brown except coxae, metafemur and metatibia black, and mesofemur and two apical segments of tarsi brown.

Antenna ( Fig. 13View FIGURES 13 – 18) with radicle 0.1–0.2× total length of scape, rest of scape 2.8–4.3× as long as wide; pedicel much longer than F1; F1 the shortest funicle segment, F3 longer than F2 and F4, F3 and F5 subequal in length (the longest funicle segments), the following funicle segments usually progressively slightly shorter than preceding ones; mps on F3 (2), F4 (0 or 1), F5 (usually 2, occasionally 1 on one antenna), F6 (1 or 2), F7 (2) and F8 (2); clava with 8 mps, 3.8–5.0× as long as wide.

Mesosoma shorter than metasoma. Propodeum ( Fig. 14View FIGURES 13 – 18) with submedian carinae complete, curving anteriorly and posteriorly. Fore wing ( Fig. 15View FIGURES 13 – 18) 2.8–3.4× as long as wide, longest marginal seta 0.1–0.2× maximum wing width, disc with a brownish tinge throughout, mostly bare behind venation except for a few setae behind stigmal vein, and densely setose elsewhere. Hind wing 24–25× as long as wide.

Ovipositor ( Fig. 16View FIGURES 13 – 18) occupying 0.7–0.9× length of gaster, not exserted beyond its apex, 0.9–1.4× as long as mesotibia.

MALE. Body length 1075 µm. Color and size similar to female. Antenna ( Fig. 17View FIGURES 13 – 18) with F1 1.3× as long as wide. Fore wing 3.3× as long as wide. Genitalia ( Fig. 18View FIGURES 13 – 18) about 0.6× length of gaster.

Distribution. Holarctic ( Triapitsyn 2013a), who also recorded Gonatocerus  ? latipennis  from the Palearctic part of mainland China, Japan, Far East of Russia, and from the high altitude area in Taiwan which is an outpost of the Palearctic fauna, although most of the island is within the Oriental ecozone.

Hosts. Unknown.

Comments. We identify the specimens from China only tentatively as G.? latipennis  because the possibility exists that they may represent an undescribed species that is very difficult to distinguish morphologically from the real G. latipennis ( Girault 1911)  . Two females from Baoji, Shaanxi, have F8 of the antenna relatively longer and in one specimen from Ningshan, Shaanxi, the funicle is deformed, with F5 partially fused to F6.
