Holotype (SCAU), ♀, CHINA: Hainan, Mt. Yinggeling, 2008.v.1-2, Jing-xian Liu, No. 200800051. Paratypes, 2 ♂ (SCAU), CHINA: Hainan, Mt. Yinggeling, 16.xi.2008, Zai-fu Xu, No. 200800189; CHINA: Guangdong, Mt. Guanyinshan, 15-16.ix.2007, Zai-fu Xu, No. 200800179; 1 ♂ (RMNH), id., but No. 200800180.

Diagnosis.

Vertex finely transversely striate (Fig. 55); frons of female with 3 triangular ivory streaks and not reaching level of anterior coronal tooth (Fig. 57); temple smooth and shiny, with a short ivory streak along eye (Fig. 56); neck in lateral view without transverse carinae and flat medially or slightly impressed (Figs 50, 51); pronotum mostly coriaceous; propodeum finely foveolate; pterostigma long and narrow, subparallel-sided, apically acute (Fig. 49); vein 2-CU1 of fore wing absent (Fig. 49); both large teeth on hind femur largely dark brown or blackish (Fig. 53); ovipositor sheath completely black (Fig. 54).

Description.

Holotype, female, length of body 12.5 mm, of fore wing 6.7 mm, and of ovipositor sheath 11.8 mm.

Head. Antenna with flagellomeres partly missing; frons with spaced striae and microreticulate (Fig. 57); three anterior coronal teeth large and acute, two posterior ones short and wider; coronal area with some longitudinal carinae; vertex flat and finely transversely striate (Fig. 55); temple smooth and shiny, narrowly rounded behind eye (Fig. 56).

Mesosoma. Pronotum (Figs 50, 51) slender and mostly coriaceous; neck anteriorly deeply emarginated and flat medial-dorsally; posterior pronotum narrowly smooth; anterior half of mesoscutum transversely striate, posterior half with shallow foveolae; scutellum (Fig. 52) smooth and aciculate, laterally with some small punctures; mesopleuron robust, microreticulate and sparsely punctured, anterior third densely setose; metapleuron and propodeum (Fig. 52) finely foveolate and rugulose in between.

Wings. Fore wing (Fig. 7): wing hyaline, vein 2-CU1 absent; pterostigma elongate and subparallel-sided, acute apically, 15 times as long as its maximum width and 2.7 times as vein r; vein r and vein SR1 obtuse-angled, vein r ends 0.2 times length of pterostigma behind level of apex of pterostigma; vein SR1 subparallel to costal margin.

Legs. Hind coxa transversely striate, subapex dilated; hind femur (Fig. 53) rugulose or microreticulate, with 2 large ventral teeth and with a comparatively smaller obtuse basal tooth; hind tibia coriaceous, 1.1 times as long as hind femur; basal narrow part of hind tibia 1.1 times as long as widened part, inner side of widened part basally distinctly depressed, followed by convex and setose area, apically densely setose.

Metasoma. First tergite transversely striate, 15.3 times as long as its maximum width, 2.5 times as second tergite and 0.9 times as remainder of tergites; second tergite basal 0.2 rugose, remaining tergites largely smooth or weakly aciculate; pygidial area distinctly differentiated, pygidial impression reverse V-shaped; ovipositor sheath completely black (Fig. 54) and 0.9 times as long as body length.

Colour.Largely black; frons with 3 short ivory streaks not reaching level of anterior coronal tooth (Fig. 57); hind legs largely dark brown.

Male. Similar to female, but differ in: comparatively smaller in size, body length 7-9.5 mm; ivory or yellowish streaks longer and reach level of anterior coronal tooth.

Distribution.

Oriental China (Guangdong, Hainan).

Etymology.

The species was named brevimaculatus because of the short ivory streaks on the frons.
