Mesosoma. Length of mesosoma 1.3 times its height; pronope absent, but posteriorly with a transverse and indistinctly crenulate groove and no antescutal depression; side of pronotum largely smooth, antero-medially and ventro-posteriorly finely crenulate (Fig. 2 View Figure 2 c), ventral area moderately convex, medium-sized and yellowish-orange; precoxal sulcus entirely impressed, but only anteriorly and medially moderately crenulate (Fig. 2 View Figure 2 c); mesosternal sulcus medium-sized and moderately crenulate (Fig. 1 View Figure 1 b); metapleuron smooth dorsally and medially, rugose ventrally; notauli absent, only anteriorly with horizontal carina (Fig. 2 View Figure 2 d); medio-posterior depression of mesoscutum absent; mesoscutum glabrous (except for a few setae), smooth, strongly shiny and with complete lateral carina; scutellar sulcus medium-sized, transverse and deep, with one long and two short crenulae; axillar depression narrow, smooth and rather shallow (Fig. 2 View Figure 2 d); scutellum slightly convex; anteriorly metanotum with short median carina and not protruding dorsally (Fig. 2 View Figure 2 c); surface of propodeum mainly smooth, without lateral protuberance, its medio-longitudinal carina distinctly lamelliform and protuberant and posteriorly with narrow triangular medial area (Fig. 2 View Figure 2 c,d).
Wings. Fore wing: 2-SR oblique; r:3-SR:SR1 = 4:20:57; r vertical and about as long as width of pterostigma, narrow (about 4 times as long as its own width), distance between base of pterostigma and base of vein r 2.6 times as long as vein r and distinctly angled with 2-SR (Fig. 2 View Figure 2 a); disco-marginal cell slender (Fig. 2 View Figure 2 a; pterostigma narrow elliptical; SR1 straight and ending nearly at apex of wing; 1-CU1:2-CU1 = 1:9; 2-SR:3-SR:r-m = 11:20:3; r-m oblique; first subdiscal cell open ventrally and apically; CU1a at level of 2-CU1; m-cu slightly converging to 1-M. Hind wing: narrow apically; no trace of cu-a and m-cu; basal cell open posteriorly and veins largely hardly or not sclerotised (Fig. 2 View Figure 2 b).
Legs. Hind coxa smooth; tarsal claws very slender (Fig. 2 View Figure 2 f and j), no distinct protuberance but widened basally; middle femur slender and parallel-sided; middle tibia moderately erect setose (Fig. 2 View Figure 2 f); fourth segment of middle tarsus 1.5 times longer than wide in dorsal view and bristly setose and bristles somewhat shorter than twice width of segment; length of femur, tibia and basitarsus of hind leg 5.4, 10.1 and 6.0 times their width, respectively; hind femur largely smooth and parallel-sided, but basally narrowed; hind tibia with erect setae, somewhat widened apically and subbasally setose; hind tarsal segments with rather short and sparsely setose ventro-apical protuberance (Fig. 2 View Figure 2 j); hind basitarsus comparatively slender and parallel-sided, apically with medium-sized acute lamella (Fig. 2 View Figure 2 j); length of hind tibial spurs 0.20 and 0.25 times hind basitarsus.
Metasoma. Length of first tergite equal to its apical width, its surface distinctly convex medially and finely rugose medially, remainder largely smooth (Fig. 2 View Figure 2 e), its dorsal carinae distinct in basal 0.9 and tergite widened behind spiracles (Fig. 2 View Figure 2 e); dorsope rather large; second tergite smooth; ovipositor straight; length of setose part of ovipositor sheath 0.37 times fore wing, equal to metasoma, 1.6 times hind femur and 1.1 times hind tibia, with very long setae, ribbon-shaped (except apically) and with a short apical spine; hypopygium medium-sized and apically subtruncate (Fig. 1 View Figure 1 a).
Colour. Black or dark brown; pedicellus of antenna brown; palpi, tegulum, coxae, trochanters, trochantelli and metasoma largely medio-ventrally (including hypopygium) pale yellowish; scapus and remainder of legs (but telotarsi infuscate) brownish-yellow; humeral plate and remainder of antenna dark brown; mandible (but margins darkened), propleuron, pronotal side ventrally and first tergite orange; pterostigma, parastigma and vein r brown; wing membrane slightly infuscate.
Variation. Length of fore wing 1.8-2.9 mm; antenna of ♀ with 21(2), 22(2), 23(3), 24(3), 25(9) or 26(6) segments; third antennal segment 0.6-0.8 times as long as fourth segment; metasoma ventrally often largely dark brown and only hypopygium yellowish; third antennal segment of ♀ usually slender (Fig. 2 View Figure 2 l), but sometimes robust, 3.8-5.0 times longer than wide; second submarginal cell of fore wing slender in small specimens (Fig. 2 View Figure 2 a) to robust in larger specimens, 2.5-2.8 times longer than its maximum width; vein 2-SR of fore wing 2.4-2.8 times as long as vein r; vein 1+2-CU1 of fore wing distinctly pigmented in nearly all specimens; propodeal areola present, narrow triangular or medium-sized to narrow parallel-sided and dorsally distinctly protruding. The only male examined is very similar to females and it has 27 antennal segments.
