Diagnosis
Head in dorsal view slightly widened behind eyes (Fig. 31); posterior half of pronotum moderately low and dorso-posteriorly finely transversely rugose (Figs 26, 27); first subdiscal cell of fore wing comparatively robust and about 2.5 times longer than wide (Fig. 25); hind coxa largely smooth (except some short striae) and with a small (in lateral view acute) subapical dorsal tooth (Figs 29, 35); first metasomal tergite irregularly transversely rugose and about 2.4 times as long as its apical width (Fig. 28); first metasomal segment wide in lateral view (Fig. 30); second-third tergites blackish or dark brown (Fig. 24); subapical ivory band of ovipositor sheath of female about 1.7 times as long as apical blackish part (Figs 24, 34).
Description
Holotype, female, length of body 15.0 mm, and of fore wing 9.9 mm.
Head. Antenna with 29 (right) or 30 (left) segments; frons (Fig. 32) coarsely transversely rugose anteriorly and remainder reticulate-rugose; three anterior coronal teeth large and rather acute, both posterior ones arcuate and lamelliform, with one small lobe-shaped carina on each side in front of both posterior ocelli; behind coronal area with five curved, progressively smaller carinae followed by rugae laterally and fine transverse carinae medially, remaining narrowly separated from occipital carina (Fig. 31); temple smooth and shiny except for some small punctures near eye, slightly widened behind eyes and rather rounded in dorsal view (Fig. 31).
Mesosoma. Neck (Figs 26, 27) short and stout, anteriorly with 3 lamelliform carinae; middle and oblique part of pronotum largely smooth and with a distinct, sinuate carina medio-posteriorly and obliquely striate laterally; posterior part of pronotum medio-dorsally smooth and laterally indistinctly rugose; lateral oblique groove of pronotum rather narrow and smooth, but anteriorly with some crenulae; propleuron coriaceous laterally, smooth (except some punctures) and shiny ventrally; mesonotum irregularly and sparsely foveolate medially and area between fovea smooth, laterally transversely striate (Fig. 27); notauli and median groove shallow, crenulate; scutellum largely smooth medially, foveolate laterally (Fig. 27); axillae rugose-foveolate; mesopleuron strongly convex, convex part rugose-foveolate and covered with greyish setae, flat dorso-posterior part superficially rugose; mesosternum anteriorly superficially rugose-punctate and posteriorly coriaceous and laterally sparsely punctate; medial convex part of metapleuron coarsely rugose and with short greyish setae, antero-ventrally weakly crenulate, with antero-dorsal depression deep and antero-ventral depression less impressed; propodeum densely finely and irregularly rugose (Fig. 27).
Wings. Fore wing (Fig. 25): vein 1-M strongly curved and 2.4 times as long as vein 1-SR; vein r ends before level of apex of pterostigma; first subdiscal cell robust, 1.8 times as long as its maximum width.
Legs. Hind coxa stout, largely smooth, with some short striae and with a small (in lateral view acute) subapical dorsal tooth (Figs 29, 35); hind femur moderately slender, finely granulate and covered with sparse whitish setae, ventrally with 3 acute teeth (the basal one small) and some small teeth (denticles; Fig. 29); hind tibia 1.2 times as long as hind femur, basal narrow part of hind tibia 0.6 times as wide as widened part and with long ventral carina, widened part ventrally distinctly obliquely carinate (Fig. 29); length of hind basitarsus 3.6 times as long as wide.
Metasoma. First tergite stout, sub-cylindrical, 2.1 times as long as its maximum width and about 2.4 times as long as its apical width (Fig. 28), irregularly transversely rugose, posteriorly less developed than anteriorly, laterally with whitish setae; second tergite slightly shorter than first tergite and smooth except some short crenulae medio-anteriorly (Fig. 28); remainder of tergites smooth and shiny; ovipositor sheath 1.9 times as long as body and 2.9 times as long as fore wing.
Colour. Dark brown; head, scapus, pedicellus, fore leg (but tibia ivory basally), middle and hind tarsi and propleuron brown; malar space pale brown; wing membrane (but basally and area below base of pterostigma subhyaline) infuscate; all tibiae ivory basal band; subapical ivory band of ovipositor sheath of female about 1.7 times as long as apical blackish part (Fig. 34).
Male. Very similar to female, length of fore wing 10.0-10.2 mm, and of body 16-17 mm; both with 29 antennal segments and first tergite 2.4-2.5 times its apical width.
Distribution
Palaearctic: Korea, China (new record).
