Cosmocomoidea rugosa Aishan, Triapitsyn & Xu  sp. n.

( Figs 23–27View FIGURES 23 – 27, 33View FIGURES 33 – 34. 33)

Type material. Holotype ♀ [ FAFU] (on slide, Fig. 33View FIGURES 33 – 34. 33): CHINA, GUANGDONG, Guangzhou , 23.iv.1992, D. G Liu (Liu Deguang)  . Paratypes (on slides): CHINA: GUANGDONG, Guangzhou, D. G. Liu : 23.iv.1992 [2 ♀, FAFU]  ;, D. G. Liu [1 ♀, FAFU]. YUNNAN, Lijiang , 1.viii.1984, C. Li [1 ♀, FAFU]  .

Description. FEMALE (holotype and paratypes). Body length 1375–1750 µm. Body color brown to dark brown, antenna brown except clava dark brown, legs yellow except coxae dark brown.

Antenna ( Figs. 23, 27View FIGURES 23 – 27) with radicle about 0.2× total length of scape, the rest of scape 3.1× (2.9–3.7×) as long as wide; F1 shorter than pedicel and the shortest funicle segment, F2–F5 equal in length, F6–F8 shorter than preceding funicle segments; mps on F2–F8 (2 on each); clava with 8 mps, 3.2× (3.2–3.9×) as long as wide.

Mesosoma a little shorter than metasoma. Propodeum ( Fig. 24View FIGURES 23 – 27) rugose lateral to submedian carinae, the carinae slightly curving and narrowing, and extending to anterior margin. Fore wing ( Fig. 25View FIGURES 23 – 27) 2.5× (2.5–2.8×) as long as wide, longest marginal seta 0.12× (0.11–0.17×) maximum wing width; disc mostly bare behind venation except for a few setae behind stigmal vein. Hind wing about 15.0× as long as wide.

Ovipositor ( Fig. 26View FIGURES 23 – 27) occupying 0.8× (0.8–1.0×) length of gaster, not or barely exserted beyond its apex, 1.4× (1.3–1.4×) as long as mesotibia.

Measurements (µm) of holotype. Mesosoma 664; petiole: 45; gaster 703; ovipositor 594. Antenna: radicle 53; rest of scape 233; pedicel 83; F1 53; F2 75; F3 80; F4 75; F5 75; F6 65; F7 60; F8 50; clava 587. Fore wing 1425:575; longest marginal seta 69. Hind wing 1069:69; longest marginal seta 89.

MALE. Unknown.

Recognition. Cosmocomoidea rugosa  is most similar to C. kodaiana  to which it keys in Zeya & Hayat (1995). Females differ from those of the latter by F2 ( Fig. 27View FIGURES 23 – 27) bearing 2 mps whereas in C. kodaiana  F2 bears only 1 mps. The ovipositor of C. rugosa  is also notably longer than mesotibia (at least about 1.3×) whereas in C. kodaiana  the ovipositor is either about equal to (in the specimens from China) or a little shorter than the mesotibia ( Zeya & Hayat 1995). Females of C. rugosa  differ from those of C. tenuis  by their rugose propodeum, and mps are present in C. Tenuis  only on F3 (1), F4 (1 or 2), and F5–F8 (2 on each), whereas in C. rugosa  mps are present on F2–F8 (2 on each).

Distribution. Oriental: China (Guangdong, Yunnan).

Etymology. The species name refers to the rugose propodeum.

Hosts. Unknown.
