F e m a l e

F l a g e l l u m: Bristle-shaped, with 42 segments, moderately thick, with white annulus on segments 6-12, strongly thickened and flattened ventrally behind middle and attenuated to apex; segments before white annulus strongly differentiated, first segment short, 1,4 times longer than the width at apex, already segment 4 square from lateral;

flagellum up to white annulus reddish-brown, beyond it brownish-black. Flagellum 1,4 times shorter than the front wing and 1,75 times shorter than body length.

H e a d: Head contour from front quite slightly narrowed downwards, only just transverse, only 1,1 times wider than height; genae long, from front (malar space) 3,3 times shorter than height of an eye (0,3); head contour from above transverse, 2,2 times wider than length in middle and 1,8 times along an external contour, slightly roundly narrowed backwards behind eyes. Vertex from lateral linearly sloping from ocelli to occipital carina; temples long, in middle 1,3 times longer than longitudinal diameter of an eye, parallel to hind margin of an eye, behind eyes from above slightly roundly narrowed; occipital carina sharp all round, from above strongly roundly impressed, far not reach level of eyes and hind ocelli; hypostomal carina not visible from lateral, occipital carina meeting with hypostomal carina some before base of mandible; abscissula equal 0,3 of mandible base width; malar space 1,3 times shorter than the mandible base width; mandibles narrow, evenly narrowed from base to apex, the most part parallel-sided, upper tooth considerably longer than lower one, broad, flattened, not sharpened; clypeus broad, flat, 2,6 times wider than length, with straight thinned front margin and rounded lateral corners, separated from face, by slight impression; clypeal foveae small, deep; labrum almost equal by breadth to front margin of clypeus, roundly-triangular, short, with long pubescence along front margin; middle field of face distinctly elevated, in middle narrower than the lateral fields; antennal cavities strongly impressed, reach borders of eyes and almost reach front ocellus level, laterally above antennal fossae with tubercles and with tubercle between antennal fossae; margins of antennal fossae thick, high elevated above face surface; ocelli of normal size, diameter of lateral ocellus 1,5 times less than distance from ocellus to eye; ocellar triangle slightly, but distinctly elevated. Surface of clypeus and lateral fields with distinct smoothed punctures, polished, middle field with more sharp punctures to slightly wrinkled, frons above antennal cavities roughly-punctured, temples superficially punctured.

T h o r a x: Collar of pronotum from above long, with straight front margin; transverse furrow of pronotum deep, narrow, sharp; pronotal ridge not swollen, narrow; epomiae sharp; pronotal base gradually curved. Mesonotum slightly convex, only just (1,1 times) longer than width; notauli in a form of very slight impressions at base; surface of mesonotum with sparse punctures, polished; axillary tongue developed, but weak; subalarum high, moderately thick, not sharpened; speculum with sparse punctures, polished; mesopleural fovea sharply expressed, deep, area of mesopleural fovea narrowly impressed; mesopleural suture straight, deep, interrupted by sharp ribs; mesopleurae at bottom without sharp bend; sternauli in a form of indistinct impressions up to middle of ventral surface; lower part of mesopleurae wrinkly-punctured, shining, upper one densely punctured, without microsculpture; scutellum from lateral moderately elevated above postscutellum, from above almost flat, laterally not carinated. Hind margin of metanotum with triangular projections opposite of lateral longitudinal carinae. Propodeum from lateral with angular break, length of convex horizontal part 1,7 times shorter than length of area posteromedia in middle; carinae of propodeum expressed, with exception of costulae; basal area short and deep; area superomedia transverse (slightly hexagonal), 1,5 times wider than length, high elevated; areae dentiparae at apices with slight denticles; spiracles long, slit-shaped, along external contour 3,5 times longer than width. Surface of propodeum, including metapleurae, roughly-wrinkled, with exception of roughly punctured areae superoexternae, shining, without microsculpture.

L e g s: Slender, long. Hind coxae without scopa. All tibiae with sparse spinules. Claws long, uniformly curved.

W i n g s: Areolet pentagonal, slightly asymmetrical, external vein of apex shorter than internal one; stigma rather broad, light; radial cell long, broad; radius almost straight, curved only at apex; nervulus postfurcal; ramulus long; all veins light, reddish-brown; membrane of wing yellowish. Front wing longer than length of flagellum and shorter than body length.

A b d o m e n Amblypygous, from above broadly-oval, apex of abdomen compressed from sides, sixth tergite retracted; second tergite transverse, at apex 1,5 times wider than length; sheath of ovipositor hidden. First tergite from lateral with distinct bend between petiolus and postpetiolus, sharply developed only ventrolateral carina, from lateral with strong transversal ribs; from above petiolus sharply broadened to quadrangular behind spiracles postpetiolus; distance between spiracles many more than distance from spiracles to hind margin of tergite; middle field of postpetiolus sharply expressed and high elevated, 1,8 times wider than lateral fields, its surface longitudinally-wrinkled (striated). Gastrocoeli short, deeply impressed, slightly obliqued, narrower than interval; thyridiae not developed (only just marked); lunulae distinct, of moderate size; surface of second tergite up to apex very densely punctured to slightly wrinkled; third tergite densely superficially punctured by very small punctures, tergites 4-5 coriaceous, 6-7th smooth. Hypopygium triangular from lateral, not compressed from sides and with fascicle of long stiff bristles at apex; sternites 2-4 unsclerotized on the larger part, 5th with membranous apical margin.

C o l o r a t i o n: Body black with reach yellow and reddish-brown pattern; reddishbrown: internal and external (partially) orbits, hind corners of pronotum, most part of abdominal tergites; yellow: internal orbits in part, spot on subalarum, scutellum, apical bands on postpetiolus and second tergite, membranous part of abdominal sternites. Femora of all legs black on the larger part, tibiae and tarsi reddish-brown.

S i z e: Body length: 14,5; front wing: 11,0; flagellum: 8,0 mm.
