Flagellum 1,2 times shorter than the front wing and 1,3 times shorter than body length.

H e a d: Head contour from front almost rectangular, 1,3 times wider than height, genae roundly narrowed downwards, long, temples from front visible almost to middle of eye; malar space 3,5 times sorter than height of eye; from above contour slightly transversal, 1,6 times wider than length. Vertex from lateral gradually oblique to high occipital carina; temples from above long, gradually roundly narrowed behind eyes, from lateral at middle equal by length to longitudinal diameter of eye; occipital carina from above almost not impressed to ocelli, straight, from lateral parallel to hind margin of eye, meeting with hypostomal carina on considerable distance from mandible base; malar space approximately equal to mandible base width; mandibles massive, gradually narrowed from base to apex, with strong teeth; clypeus slightly separated from middle field of face, transversal, 1,9 times wider than length, slightly uniformly convex, approximately same height with middle field and gradually turn into middle field of face, corners of clypeus not rounded, sharp, front margin straight; labrum very long, wide, triangle; clypeus and middle field of face high elevated above lateral fields; clypeal foveae big, deep; middle field of face sharply limited, in middle 1,3 times narrower than lateral fields; antennal cavities very deep, reach level of front ocellus and not reach borders of eyes, without lateral tubercles and with very strong, high and narrow tooth (almost keel) between antennal fossae; margins of antennal fossae high elevated above face surface; ocelli of normal size, diameter of lateral ocellus 2,2 times less than distance from ocellus to eye; ocellar triangle not elevated. Head surface dull with big superficial punctures, more sparse on clypeus.

T h o r a x: Collar of pronotum long; transverse furrow of pronotum narrow and deep. Mesonotum moderately convex, long, 1,3 times longer than width; notauli not expressed, only in form of only just visible impressions at base of mesonotum; surface of mesonotum very densely punctured, to wrinkle-punctured on middle lobe, dull with developed microsculpture; prepectal carina very strongly curved backwards and considerable part of prepectus (epicnemium) visible from side; subalarum extraordinary thick; speculum shining with very big punctures; area of mesopleural fovea very deeply impressed; mesopleural suture straight, deep, interrupted by strong ribs; sternauli practically absent, only in form of very slight impressions at base; lower part of mesopleurae with distinct bend; surface of mesopleurae at upper half densely punctured, at lower wrinkly-punctured to irregularly-wrinkled, without microsculpture; scutellum from lateral triangle (slanted from apex to postscutellum), with rounded apex, not carinated laterally; surface of scutellum with sparse superficial punctures, intervals between punctures with coriaceous sculpture. Hind margin of metanotum with triangle, curved downwards projections. Propodeum from lateral roundly-convex, without break; horizontal part of propodeum 1,5 times shorter than length of area posteromedia in middle; carinae, limiting basal area, area superomedia, coxal area and costulae not developed; area superomedia marked by cellular structure and high elevated above lateral fields; areae dentiparae apically with blunted transversal projections; only carina metapleuralis distinctly developed; spiracles large, long and broad, equal 0,6 breadth of field at place of spiracle, length of spiracles 1,8-2,3 times longer than width. Surface of propodeum, with exception of metapleurae, cellular-wrinkled; metapleurae with big punctures to wrinkled, without microsculpture.

L e g s: Slender. Claws large, thickened and pectinate at basal part, apically slightly uniformly curved.

W i n g s: Areolet irregularly quadrangular, strongly asymmetrical (external vein of base considerably longer than internal); stigma narrow, dark; radius slightly sinuous, long; radial cell long and narrow; nervulus postfurcal; ramulus, long; membrane of wing hyaline, veins dark. Length of front wing almost equal to body length.

A b d o m e n:Abdomen from above broadly-oval, apical tergites not hidden, sheath of ovipositor from above not protrude; second tergite transversal, 1,5 times shorter than length in middle. Petiolus strongly broadened and flattened at base, laterally with sharp carinae and strong cellular sculpture between them; from lateral with gradual bend to postpetiolus, from above strongly and sharply broadened to postpetiolus; middle field of postpetiolus practically not expressed and not elevated above lateral fields, with sparse delicate not uniform punctures; surface of postpetiolus with slightly coriaceous sculpture. Gastrocoeli deep, slightly oblique; thyridia distinct, closed to base of tergite, 2,5 times wider than interval between them; lunulae practically absent; interval between thyridia with rough cellular structure, middle part of second tergite with dense punctures and slight microsculpture, apical part of tergite with sparse delicate punctures, slightly coriaceous and slightly shining; punctuation of tergite 3 superficial, on other tergites only just expressed. Hypopygium long, completely overlap slit of ovipositor, with cut apex, flat, without longitudinal fold; apex of ovipositor sheath from lateral only just protrude.

C o l o r a t i o n: Female black with numerous yellow spots; yellow: frontal and facial (broadly) orbits, external orbits (broadly), clypeus, upper margins of pronotum (broadly) and small spots on sides apically, spot on mesonotum, subalarum completely, spots on prepectus and large spots on mesopleurae, scutellum completely and postscutellum, spots on sides of metathorax, apex of metapleurae, large spots at area of apophysises, apical spots at corners of tergites 1-7 of abdomen, on all coxae, apices of femora and tibiae, tarsi of all legs yellow.

S i z e: Body length: 19,5; front wing: 17,4; flagellum: 14,5 mm.
