Vertex from lateral linearly abrupt from hind border of ocelli to occipital carina; temples in middle 1,2 times longer than longitudinal diameter of an eye, parallel to hind margin of an eye; occipital carina sharp all round, from above deeply and roundly impressed, but not reach level of eyes and hind ocelli; hypostomal carina not visible from lateral, occipital carina meeting with hypostomal one before base of mandible; abscissula 1,1 times shorter than mandible base width; malar space equal by length to mandible base width; mandibles rather broad, parallel-sided in middle part, with long upper tooth and short lower one, separated by narrow impression; clypeus only just convex, 2,2 times wider than length, with straight (slightly concave) thinned front margin and distinct only just rounded lateral corners, distinctly separated from middle and lateral fields of face by suture; clypeal foveae sharp, deep; labrum protrude from under clypeus, rounded, some narrower than front margin of clypeus; middle field of face distinctly but slightly elevated above lateral fields, in middle equal by breadth to lateral fields, distinctly separated from them by slight impressions; antennal cavities not big, sharply and very deeply impressed, merged on the larger part, reach borders of eyes and far not reach front ocellus level, with polished surface, laterally above antennal fossae with tubercles and with sharp interantennal tubercle; margins of antennal fossae distinctly but slightly elevated above face surface; ocelli of normal size, diameter of lateral ocellus 1,3 times less than distance from ocellus to eye; ocellar triangle slightly but distinctly elevated. Surface of clypeus densely punctured at base and laterally and shining apically; middle and most part of lateral fields densely punctured by almost merging punctures, lower part of lateral fields shining; frons above antennal cavities sharply irregularly-wrinkled; vertex and temples on top slightly wrinkled, most part of temples densely punctured by smoothed punctures, shining.

T h o r a x: Collar of pronotum from above rather short with straight front margin; transverse furrow of pronotum narrow, deep; pronotal ridge not swollen, narrow, pronotum impressed to border with mesonotum; epomiae sharp, short; pronotal base gradually curved; lateral surface of pronotum at lower part strongly longitudinally-wrinkled and at upper one densely punctured by small punctures. Mesonotum strongly convex, 1,2 times longer than width; notauli sharply impressed in front third; surface of mesonotum very densely punctured, by small punctures, shining medially; axillary tongue developed; considerable part of prepectus visible from lateral, prepectal carina almost reach pronotum; subalarum narrow, high, almost sharpened; speculum smooth, shining; mesopleural fovea sharp, deep, area of mesopleural fovea narrowly deeply impressed; mesopleural suture straight, deep, interrupted by rather slight ribs; mesopleurae at bottom with rather distinct but smoothed bend; sternauli in a form of very indistinct broad impressions at base; surface of mesopleurae densely punctured by small punctures to wrinkly-punctured in hind lower third, shining, upper third punctured in front, area under subalarum wrinkled; scutellum high elevated above postscutellum, gradually sloped backwards with slightly convex horizontal part, laterally not carinated. Hind margin of metanotum with triangular projections opposite of lateral longitudinal carinae. Propodeum from lateral gradually convex, but distinctly box-shaped with strongly elevated area superomedia; length of horizontal part of propodeum 1,7 times shorter than length of area posteromedia in middle; carinae of propodeum, with exception of costulae, sharply expressed, high at the apex of horizontal part; basal area short and deep without tubercle; area superomedia big quadrangular, only just transverse, 1,3 times wider than length; areae dentiparae at apices without teeth, external carina of area dentipara almost parallel to carina metapleuralis (remind Protichneumonini ); spiracles big, long, along external contour 2,4 times longer than width. Surface of propodeum from punctured in front part of lateral fields to densely wrinkled on the larger part; metapleurae wrinkly-punctured; surface shining, without microsculpture.

L e g s: Slender, long. Claws thin, sharply curved almost at right angle. Hind coxae without scopa.

W i n g s: Areolet big, pentagonal, slightly asymmetrical (external vein of apex shorter than internal one); stigma normal, dark; radial cell narrow, long; radius slightly sinuous; nervulus postfurcal; ramulus not expressed (only just marked); veins dark; membrane of wing hyaline. Front wing almost equal by length to flagellum and 1,5 times shorter than body length.

A b d o m e n Amblypygous, from above longish-oval, apical tergites not hidden, tergite 7 far protrude from under 6; second tergite slightly elongated, width at apex 1,1 times less than length in middle; tergites 2-4 separated by sharp constrictions, strongly convex medially; sheath of ovipositor not protrude from above. First tergite from lateral with distinct bend between petiolus and postpetiolus; dorsolateral carina only just marked, dorsal and ventro-lateral carinae sharp, from lateral petiolus sculptured by sharp transversal ribs; from above petiolus sharply broadened to postpetiolus; distance between spiracles many more than distance from spiracles to hind margin of tergite; middle field of postpetiolus distinctly elevated and carinated; dorsal carinae at level of spiracles high elevated; middle field some wider than lateral fields, its surface regularly longitudinally striated. Gastrocoeli deep, 2 times narrower than interval between them, interval equal by breadth to middle field of postpetiolus, thyridia practically not developed; lunulae distinct, not big; interspace between thyridia with sharp longitudinal striation, surface of second tergite medially almost up to hind third longitudinally wrinkly-punctured, other part of tergite 2 and tergite 3 entirely densely punctured by small punctures, shining, other tergites smooth.
