Diagnosis.

Frons densely foveolate-rugose (Fig. 271); temple dark brown and with ivory streak along eyes distinctly contrasting with surroundings (Fig. 270); pronotum robust and weakly rugose (Figs 266, 267); propodeum coarsely and irregularly foveolate (Fig. 268); pterostigma comparatively long and about 5.5 times as long as wide (Fig. 265); first discal cell of fore wing comparatively narrow and its length about 3.1 times as long as vein 1-M (Fig. 265); hind coxa comparatively short and wide in lateral view (Fig. 273); basal narrow part of outer side of hind tibia distinctly carinate; apical large tooth of hind femur comparatively narrow and acute (Figs 275, 276); middle basitarsus of female about 6 times as long as its medial with; first tergite of female comparatively robust; ovipositor sheath about 1.4 times as long as body; pygidial process of female medium-sized (Fig. 274).

Description.

Holotype, female, length of body 16.2 mm, of fore wing 9.9 mm, and of ovipositor sheath 22.9 mm.

Head. Flagellum with 33 flagellomeres; frons coarsely reticulate-rugose (Fig. 271); three anterior coronal teeth acute, both posterior ones wide and arcuate, sculpture on coronal area from rugose anteriorly to longitudinally short carinate; behind level of coronal area with five strong, curved carinae, followed by transversely rugose area, rugae coarse anteriorly, finer laterally near eye and posteriorly, striae posteriorly weaker and narrowly reaching to occipital carina (Fig. 269); temple smooth and shiny, relatively broad, gena round (Fig. 270).

Mesosoma. Neck (Figs 266, 267) short and robust, anteriorly distinctly emarginate, medio-posteriorly smooth, and with pairs of oblique lateral carinae, neck at much lower level than remainder of pronotum; pronotal fold and concavity absent; middle pronotum steeply elevated and subvertical to neck, largely transversely striate; posterior pronotum not differentiated from middle part, weakly striate dorsally and sparsely with punctures laterally and more or less smooth apically (Fig. 266), pronotal lobe with oblique carinae; lateral oblique groove of pronotum narrow and indistinct, ventral area below it distinctly obliquely striate (Fig. 267); propleuron relatively wide, coriaceous and microreticulate; prosternum densely transversely striate and pubescent; mesoscutum foveolate, anterior 0.2 and area between foveolae striate, latero-posteriorly somewhat rugose; notauli and median groove distinct and formed by some foveolae or crenulae; axilla irregularly densely striate, rugose-foveolate near scutellum; scutellum (Fig. 268) laterally densely foveolate and medially rugulose; mesopleuron rather robust, dorsally flat and largely smooth, convex ventral part shallowly rugose and pubescent, anteriorly pubescence denser and rugae coarser than posteriorly; mesosternum largely striate and anterior part pubescent; convex part of metapleuron coarsely reticulate-rugose and sparsely setose, ventral part below it finely striate; propodeum irregularly foveolate, foveolae changing from circular to suboval, area in between and inside foveolae striate, foveolae laterally and apically somewhat coalescent and reticulate (Fig. 268).

Wings. Fore wing (Fig. 265): vein 1-M 1.25 times as long as vein 1-SR and 0.9 times vein m-cu; vein cu-a slightly postfurcal and subvertical; vein 2-SR 1.25 times as long as vein r; vein r ends 0.3 times length of pterostigma behind level of apex of pterostigma; vein r and vein 1-M distinctly curved; vein 1-SR 1.4 times as long as parastigmal vein; vein 3-CU1 basal 0.2 tubular, remainder largely nebulous, apically distinctly curved.

Legs. Hind coxa (Figs 272, 273) robust, antero-dorsally rugose, anterior 0.6 of outer side distinctly compressed and sculpture changing from rugose to microreticulate, posterior part of hind coxa coarsely transversely striate; hind femur (Fig. 275) strongly swollen, densely finely aciculate, ventrally with 2 large teeth and some denticles in between, basal one third part having 2 obtuse teeth much smaller; hind tibia (Figs 275, 276) about 1.2 times as long as hind femur, basal narrow part about 1.4 times as long as widened part, outer side of hind tibia distinctly obliquely carinate, narrow part of inner side coriaceous, widened part of inner side distinctly depressed basally and densely bristly setose apically; basitarsus rather robust, ventral length about 3.8 times as long as its apical width.

Metasoma. First tergite 4.6 times as long as its maximum width, 1.7 times second tergite and 0.6 times remainder of tergites, densely coarsely and rather regularly transversely striate, basal 0.1 rugose and with 2 distinct, short longitudinal carinae, apically narrowly smooth; basal 0.2 of second tergite with several short longitudinal carinae, remainder of tergite smooth; remainder of tergites densely finely microaciculate; pygidial area with two distinct projections, pygidial impression setose and somewhat reverse V-shaped (Fig. 274); ovipositor sheath (Fig. 276) about 1.4 times as long as body.

Colour. Largely black; head tricoloured: coronal teeth, vertex medio-longitudinally and narrow area of vertex behind eyes dark brown; frons and most of vertex reddish; gena narrowly along eye margin yellowish; propleuron largely yellowish; middle basitarsus with yellowish tint; fore leg, hind trochanter, hind tibia and basal 0.2 of second tergite dark reddish brown; wing membrane subhyaline; pterostigma and wing venation dark brown.

Male. Unknown.

Distribution.

China (Zhejiang).

Etymology.

The name is derived from “brevis” (Latin for short) and “coxa” (Latin for hip) because of the short hind coxa.
