Description.

Redescribed after a female from Hainan (Mt. Diaoluoshan), length of body 13.1 mm, of fore wing 7.0 mm, and of ovipositor sheath 9.1 mm.

Head. Flagellum with 30 flagellomeres; first flagellomere very short, twice its maximum width, almost equal to pedicel and half as long as second flagellomere; frons (Fig. 34) strongly reticulate-rugose, rugae extending to coronal area; three anterior coronal teeth acute, both posterior ones arcuate; vertex (Fig. 32) with four strong, curved spaced carinae followed by coarsely transversely rugose and slightly convex area; temple (Fig. 33) with weak rugae from vertex along orbit, ventrally smooth, temple roundly narrowed behind eyes; head transverse in dorsal view.

Mesosoma.Neck (Figs 27, 28) rather robust, anteriorly deeply emarginate, dorso-medially impressed, laterally with four pairs of oblique carinae, carinae interrupted dorsally, neck postero-dorsally at lower level than middle pronotum; middle pronotum coarsely transversely striate, postero-medially with a shallow foveola; posterior pronotum largely rugose, posteriorly somewhat striate, laterally convex part weakly reticulate-rugose; mesoscutum largely strongly carinate-rugose, anterior 0.2 transversely striate; notauli and middle groove distinct on anterior 0.2; axillae strongly foveolate and with striate interspaces; scutellum (Fig. 29) laterally and marginally foveolate and with striate interspaces, medially largely smooth and somewhat longitudinal striate; mesopleuron largely striate, anteriorly covered with short whitish setosity, ventrally sparsely shallowly foveolate; convex part of metapleuron strongly reticulate-foveolate, foveolae large and deeper than those on mesopleuron; propodeum (Fig. 29) mostly with median-sized, circular foveolae and with striate interspaces, inside of foveolae polished, some foveolae posteriorly coalescent and resulting two large foveae.

Wings. Fore wing (Fig. 26): wing hyaline; vein 2-CU1 0.9 times as long as vein cu-a; pterostigma obtuse apically and comparatively wide and short, 1.4 times as long as vein r and 8.3 times as its maximum width; vein r ends 0.24 times length of pterostigma behind level of apex of pterostigma; vein SR1 about 1.3 times as long as vein r; vein SR1 and vein r obtuse-angled, vein SR1 elongate towards vein margin and ending near before reaching vein margin.

Legs. Anterior 0.6 of hind coxa coarsely rugose and somewhat reticulate, posterior part transversely annularly striate; hind femur (Fig. 30) densely transversely strigate, with 3 large ventral teeth, basal tooth obtuse-triangular; hind tibia 1.2 times as long as hind femur, largely irregularly obliquely strigate, apically densely bristly setose; basal narrow part of hind tibia 1.5 times as widened part, inner side of widened part basally steeply depressed; basitarsus parallel-sided, its ventral length 4.7 times as long as its width, ventrally densely setose.

Metasoma. First tergite largely transversely striate, basal 0.2 rugose and apical 0.05 smooth, first tergite 10.2 times as long as its maximum width, 2.8 times as long as second tergite and 0.8 times as long as rest of metasoma; second tergite basal 0.2 rugose, medially largely microreticulate and apical 0.2 aciculate; rest of tergites transversely aciculate, somewhat smooth; pygidial area setose, laterally shallowly impressed, medially distinctly convex and granulate, pygidial impression widely reversed V-shaped; length of ovipositor sheath 0.7 times as long as body length, length of subapical brownish band 0.4 times length of dark apex (Fig. 31).

Colour. Largely black, except parts as follows: head dark brown with some reddish tint; frons ivory from mandibles to narrowly above antennae; scape, pedicel, posterior coronal teeth and carinae between posterior ocelli on vertex, two spots behind posterior ocelli reddish brown; basal rugose part dorsally red brown but laterally with two yellow spots; malar space, basal part of mid tibia, basal half of mid basitarsus, ventral large teeth of hind femur and hind basitarsus whitish; subapex of ovipositor sheath pale brown.

Male. Body length 16 mm; almost the same as female, but different in body colour (Chao, 1964). A specimen from Guangxi (No. 821489) with body length 11.5 mm, frons completely yellowish (Fig. 36), carinae on the neck complete and transverse (Figs 38, 39), and vein 2-CU1 of fore wing 0.3 times as long as vein cu-a (Fig. 37).

Variation. Female: length of body 6.5-15 mm, of fore wing 3.6-7.7 mm, and of ovipositor sheath 7.2-14 mm; vein 2-CU1 0.9-1.1 times as long as vein cu-a; pterostigma 1.4-1.8 times as long as vein r and 8.3-9.5 times as long as its maximum width; first tergite 9.0-12.8 times as long as its maximum width, 2.1-2.8 times as second tergite and 0.7-0.9 times as rest of tergites; length of ovipositor sheath 0.7-0.9 times as long as body length; length of subapical brownish or yellowish band of ovipositor sheath 0.4-0.8 times length of dark apex. One specimen from Hainan (No. 870229) has ovipositor sheath totally dark brown and without pale brownish part; carinae on the neck complete and not interrupted dorsally; mixed coloured, coronal area, pronotum, propodeum, first tergite largely red brown. Male: body length 11.5-16 mm; frons completely yellowish (Figs 36, 48); Neck with transverse and complete carinate (Fig. 39) or obliquely carinate (Fig. 41); vein 2-CU1 of fore wing 0.3-0.9 times as long as vein cu-a.

Distribution.

China (Yunnan, Guangxi, Taiwan, Hainan); Vietnam.

Notes.

The type series of Foenatopus yunnanensis has been examined and proved to be in the variation of Foenatopus annulitarsus . Vietnam is a new record for this species.
