F l a g e l l u m: Semi bristle-shaped, with 31 segments, stout, with weakly separated (differentiated) segments, not flattened ventrally, without traces of white pattern; basal segments short, length of first segment only 1,7 times longer than width at apex; tyloides longish-oval on segments 8-16(17). Flagellum 1,1 times longer than the front wing and 1,2 times shorter than body length.

H e a d: Head contour from front roundish, with big eyes, only 1,2 times wider than height; genae from front sharply narrowed downwards, 6,6 times shorter than height of an eye; head contour from above transversal, 1,7 times wider than length. Vertex from lateral gradually slanting down to occipital carina; temples behind eyes long, gradually narrowed backwards (from above) and sharply downwards (from side), in middle only 1,2 times shorter than longitudinal diameter of eye at middle; occipital carina not high, rather slightly, but angularly impressed to hind ocelli, far not reach level of eyes and hind ocelli; occipital carina meeting with hypostomal carina on mandible base, at place of junction sharply curved forward; malar space shorter than the mandible base width; mandibles enough short, evenly narrowed from base to apex; clypeus and middle field of face protrude on same height, forming from lateral uniform arch; clypeus slightly separated from face, at apex with straight impression, strongly transversal, forming by front margin uniform arch; clypeal foveae deep; labrum not protrude from under clypeus; middle field of face strongly elevated above lateral fields, narrowed downwards, narrower than lateral fields in middle; antennal cavities not great but deeply impressed, laterally not reach borders of eyes and far not reach front ocellus level, without lateral tubercles above and tubercle between antennal fossae; ocelli large, diameter of lateral ocellus equal to distance from ocellus to eye; ocellar triangle smoothly but quite high elevated. Clypeus punctured by big punctures (interspace narrower than punctures), without microsculpture; face and clypeus densely wrinkly-punctured, frons above antennal cavities with strong transversal rugosity.

T h o r a x: Collar of pronotum long, from above with straight front margin; transverse furrow of pronotum broad, shallow. Mesonotum moderately convex, some wider than length, notauli developed in front third; surface of mesonotum densely punctured by big punctures (intervals narrower than punctures), shining, without microsculpture; sub- alarum thin, sharp; area of speculum punctured by big superficial punctures, shining; area of mesopleural fovea moderately deeply, but not broadly impressed; sternauli expressed at first third, deep; surface of mesopleurae shining, densely punctured by big punctures, without microsculpture; scutellum convex, from above strongly narrowed backwards, without distinctly expressed lateral carinae, from lateral gradually slanting to postscutellum, horizontal part of scutellum slightly convex with big sparse punctures. Hind margin of metanotum with long bacilliform projections opposite lateral longitudinal carinae. Propodeum from lateral with angle-shaped contour, horizontal part 1,8 times shorter than area posteromedia in middle; all fields of propodeum expressed, carinae sharp, high; area superomedia hexagonal, of equal length and breadth, costulae at middle of area superomedia; spiracles small, roundish, only just longer than width (approximately 1,4 times), equal 0,3 breadth of area spiraculifera at place of spiracle; area dentipara at apex with distinct tooth. Surface of propodeum largely cellular-wrinkled with big superficial punctures, shining, without microsculpture, metapleurae wrinkly-punctured.

L e g s: Slender. Claws short, thick, at apex strongly curved.

W i n g s: Areolet pentagonal, symmetrical, narrow in front; stigma broad, light; radius slightly curved, practically straight, short; nervulus postfurcal; ramulus only marked; membrane of wing hyaline, veins light. Front wing 1,4 times shorter than body length.

A b d o m e n: From above elongated, parallel sided, in cross-section roundish, second tergite approximately equal by length to breadth at apex, apical tergites not hidden. Petiolus at base not wider than height, from lateral first tergite gradually curved without sharp break; dorsal and ventral lateral carinae of petiolus sharp, surface between carinae almost not sculptured; from above petiolus rather sharply broadened to postpetiolus; middle field of postpetiolus not expressed, postpetiolus densely punctured by big punctures, shining. Gastrocoeli slightly impressed, long, oblique; thyridia small, only just marked, narrower than interval between them; interval densely punctured; lunulae distinct, small; second and third tergites densely punctured, shining between punctures, other tergites smooth with sparse shallow punctures.

C o l o r a t i o n: Body red and black with limited white pattern on head, mesothorax and coxae.

S i z e: Body length: 6,3; front wing: 4,5; flagellum: 5,1 mm.
