Diagnosis.

Headtransverse in dorsal view and (Figs 189, 198, 208) globose in lateral view (Figs 190, 199, 209); vertex coarsely transversely carinate-rugose (Figs 189, 198, 208); face coarsely transversely striate, yellow patch on frons variable in size (Figs 191, 200, 210); pronotum transversely distinctly or weakly striate (Figs 184, 185, 193, 194, 202, 203); propodeum densely and distinctly to shallowly foveolate (Figs 186, 204); pterostigma moderately short and comparatively wide (Figs 183, 192, 201); vein 2-CU1 of fore wing nearly absent (Figs 183, 192, 201); hind femur with 3 large teeth ventrally (Figs 187, 195, 206); ovipositor sheath nearly completely brownish or black (Figs 188, 196, 207), without subapical band and about as long as body.

Description.

Redescribed after a female from Guangdong (Nanling), length of body 10.3 mm, of fore wing 5.6 mm, and of ovipositor 10.5 mm.

Head. Flagellum with 28 flagellomeres; length of first flagellomere 3.0 times its maximum width, and 0.6 times as second flagellomere; frons transversely striate, sculpture coarser near the central frontal coronal tooth (Fig. 210); three anterior coronal teeth acute, both posterior ones widely separated and arcuate; between posterior ocelli with three strong, transverse carinae, third one interrupted medially; vertex irregularly coarsely transversely carinate (Fig. 208); temples largely smooth but with some sculpture originating from vertex; temple indistinctly protruding (Fig. 209), head transverse in dorsal view (Fig. 208).

Mesosoma. Neck (Figs 202, 203) robust, dorsally with several irregular rugae, anteriorly distinctly emarginate, postero-dorsally at same level as middle pronotum; middle and posterior parts of pronotum dorsally transversely striate and coriaceous, laterally obliquely strigate, lateral convex posterior pronotum rugose; prosternum largely glabrous and coriaceous; mesoscutum anterior half transversely strigate, remainder strongly carinate-rugose; median sulcus and notauli distinct on anterior half; axillae strigate, more finely so laterally, separated basally by a large fovea and form scutellum by reverse V-shaped impressions; scutellum largely coarsely strigate and somewhat rugose laterally (Fig. 204); mesopleuron sparsely shallowly foveolate-rugose, anteriorly covered with whitish pubescence; metapleuron strongly reticulate-foveolate, ventrally with transverse carinae; propodeum strongly reticulate-foveolate, foveolae rather large, some foveolae posteriorly coalescent, and coarse inside (Fig. 204).

Wings. Fore wing (Fig. 201): wing hyaline, vein 2-Cu1 nearly absent; pterostigma widened and comparatively short, obtuse apically, 2.3 times as long as vein r and 7.4 times as its maximum width; vein r ends 0.2 times length of pterostigma behind level of apex of pterostigma; vein 2-SR 2.1 times as long as vein r; vein SR1 and vein r obtuse-angled, vein SR1 curved towards costal margin and disappearing 0.5 times its length before reaching wing margin.

Legs. Hind coxa subcylindrical, anteriorly rugose and posteriorly transversely spaced striate; hind femur finely transversely strigate, with three large ventral teeth and some denticles between posterior ones (Fig. 206); hind tibia 1.4 times as long as hind femur, basal narrow part of hind tibia coriaceous and oblique strigate, 1.4 times as long as widened part, outer side of widened part coriaceous and obliquely strigate, inner side of widened part basally depressed, followed by coriaceous, microareolate convex area, apically densely setose (Fig. 206); hind basitarsus parallel-sided, rather slender, its ventral length 5.3 times as long as its width, ventrally densely setose.

Metasoma. First tergite subcylindrical, coarsely transversely striate, 11.3 times as long as its maximum width, 2.2 times as second tergite and 0.7 times as remainder of tergites; second tergite basal 0.3 rugose, medial part coriaceous and microareolate, apical 0.1 aciculate; the rest of tergites largely aciculate; pygidial area with short hair as surroundings, slightly impressed laterally and centrally convex, pygidial impression reversed V-shaped; ovipositor sheath completely dark brown (Fig. 207), as long as body length.

Colour.Almost entirely brownish or dark brown; frons near antennae ivory; malar space ivory; temple with light brownish patch along half of eye; hind basitarsus whitish; ovipositor sheath totally brownish.

Male. Unknown.

Variation. Female: length of body 8.5-14.5 mm, of fore wing 5.6-5.9 mm, and of ovipositor sheath 10.5-14.8 mm; pterostigma 2.1-2.3 times longer than vein r; shape and size of ivory or brownish part on frons variable.

Distribution.

Oriental China (Guangdong, Guangxi, Taiwan, Hainan); Vietnam.

Note. The lectotype of Foenatopus ruficollis differs mainly by the more yellowish brown body and the less developed sculpture on body.
