Figs 11–17 View Figure

Parastephanellus politus Chao, 1964  (not Elliott, 1928): 380, 387.

Parastephanellus austrochinensis Belokobylskij, 1995: 22  (new name for junior homonym); Aguiar 2004: 65; Hong et al. 2011: 41 (as synonym of P. brevistigma Enderlein, 1913  ).

Diagnosis. Pale yellowish streak of temple moderately to hardly contrasting with brown posterior part of temple in lateral view ( Fig. 17 View Figure ), remaining separated from occipital carina in dorsal view ( Fig. 16 View Figure ); temples slightly angulate in dorsal view; frons of ♀ brownish yellow; medio-anteriorly pronotum gradually arising behind neck and superficially sculptured ( Fig. 12 View Figure ); pronotum below tegulae costate ( Fig. 12 View Figure ); pronotum stout in dorsal view ( Fig. 13 View Figure ); vein 1-M of fore wing 0.9–1.1 × as long as vein m-cu and 2.1 × vein 1-SR ( Fig. 35 View Figure ); vein 1-SR of fore wing strongly angled with vein 1-M and about as long as vein 2-M+CU1 ( Fig. 35 View Figure ); vein m-cu of fore wing approx. as long as vein 2-SR+M; sclerotized part of vein 2-M of fore wing not surpassing level of apex of vein r; vein r of fore wing ends near level of apex of pterostigma ( Fig. 35 View Figure ); pterostigma rather abruptly narrowed apically, more or less widened, not parallel-sided and 4–5 × as long as wide ( Fig. 11 View Figure ); hind coxa of ♂ approx. 3 × as long as wide in dorso-lateral view; first metasomal tergite approximately 5 × as long as its maximum width; ovipositor sheath approx. 1.7 × as long as body.

Distribution. China (Yunnan, Guangxi).

Notes. As well illustrated by Hong et al. (2011) two forms of P. brevistigma Enderlein  exist in China. One with aberrant venation of the fore wing as described in the key in this paper and typical for Taiwan (holotype of P. brevistigma  : Figs 35–42 View Figure ) and one with normal venation ( Figs 11–17 View Figure ; Chao, 1964) from continental China. Unfortunately, there is no additional material from Taiwan to study the variation of the characters used for separation, but we consider the difference in venation profound enough to reinstate P. austrochinensis  .
