Figs 62–69

Parastephanellus matsumotoi van Achterberg (in van Achterberg & Quicke), 2006: 219 –221; Hong et al. 2011: 43 –44 (p.p.).

Material. 3 ♀ + 6 ♂ (ZJUH): “[China:] Henan, Luoshan, Lingshan, 22.v.2000, Cai Ping, Nos 200101873, 200101876, 200101882, 200101884, 200101893, 200101896, 200101906, 200101908, 200101911”.

Diagnosis. Ivory streak of temple distinctly contrasting with dark brown posterior part of temple in lateral view (Fig. 69), separated from occipital carina in dorsal view (Fig. 68); temples evenly rounded in dorsal view (Fig. 68); frons of ♀ largely dark brown laterally, medially and ventrally more or less reddish brown (Fig. 67); medio-anteriorly pronotum steeply arising behind neck (Fig. 63); pronotum below tegulae costate (Fig. 63); vein 1- M of fore wing 1.1–1.3 × as long as vein m-cu and 1.1–1.5 × vein 1-SR (Fig. 62); vein 1-SR of fore wing strongly angled with vein 1-M and 1.5–2.5 × as long as vein 2-M+CU1 (Fig. 62); vein m-cu of fore wing approx. 1.5 × longer than vein 2-SR+M; sclerotized part of vein 2-M of fore wing surpassing level of apex of vein r; vein r of fore wing ends far behind level of apex of pterostigma (Fig. 62); hind coxa of ♀ 2.7–3.0 × as long as wide in dorsolateral view (Fig. 65); first metasomal tergite of ♀ slender, 6.8–7.5 × as long as wide; emargination of pygidial area of ♀ wide (Fig. 66), distinctly protruding and truncate latero-apically (Fig. 66); ovipositor sheath 1.5–1.8 × as long as body.

Distribution. China (Henan), Japan (Kyushu), Korea.

Notes. As well illustrated by Hong et al. (2011) two forms exist in China; one with anteriorly steep posterior part of pronotum (as in typical P. matsumotoi from Japan: Figs 312–324 in Hong et al. 2011; Fig. 63) and one with anteriorly gradually sloping posterior part of pronotum (Figs 325–337 l.c.; Fig. 73). Thanks to the large series from Taibai Mt. it became obvious that the specimens with gradually lowered anterior slope of the pronotum are a separate species because the different pronotum is combined with a different venation of the fore wing (see couplet 1 of the key). It is described below as P. yixiwui sp. n. from Shaanxi and Henan.
