Parastephanellus matsumotoi van Achterberg, 2006 

Figs 62–69 View Figure

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 View Figure ), separated from occipital carina in dorsal view ( Fig. 68 View Figure ); temples evenly rounded in dorsal view ( Fig. 68 View Figure ); frons of ♀ largely dark brown laterally, medially and ventrally more or less reddish brown ( Fig. 67 View Figure ); medio-anteriorly pronotum steeply arising behind neck ( Fig. 63 View Figure ); pronotum below tegulae costate ( Fig. 63 View Figure ); 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 View Figure ); 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 View Figure ); 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 View Figure ); hind coxa of ♀ 2.7–3.0 × as long as wide in dorsolateral view ( Fig. 65 View Figure ); first metasomal tergite of ♀ slender, 6.8–7.5 × as long as wide; emargination of pygidial area of ♀ wide ( Fig. 66 View Figure ), distinctly protruding and truncate latero-apically ( Fig. 66 View Figure ); 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 View Figure ) and one with anteriorly gradually sloping posterior part of pronotum (Figs 325–337 l.c.; Fig. 73 View Figure ). 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.
