Vertex from lateral linearly sloping from ocelli to occipital carina; temples long, in middle 1,3 times longer than longitudinal diameter of an eye, broadened downwards; occipital carina high, sharp all round, from above slightly roundly impressed, very far not reach level of eyes and hind ocelli, at the bottom abrupt far from hypostomal carina, between it and hypostomal carina broad impression is formed; hypostomal carina visible from lateral on considerable distance; abscissula high, sharp, 1,4 times longer than the mandible base width; malar space 1,3 times shorter than the mandible base width; mandibles narrow, evenly narrowed from base to sharp apex, without lower tooth; clypeus slightly convex, 2,1 times wider than length, with straight thinned front margin, distinct lateral corners, oblique lateral margins and with impression along front margin, separated from face, by slight broad impression; clypeal foveae normal, deep; labrum narrower than front margin of clypeus, rounded, short, with short pubescence along front margin; middle field of face only just elevated, in middle narrower than breadth of lateral fields; antennal cavities strongly impressed, reach borders of eyes and far not reach front ocellus level, with lateral tubercles and only just marked tubercle between antennal fossae; front margins of antennal fossae moderately elevated above face surface; ocelli of normal size, diameter of lateral ocellus equal to distance from ocellus to eye; ocellar triangle slightly, but distinctly elevated. Surface of clypeus with big punctures, with wrinkling along front margin; middle and lateral fields partially smoothly wrinkly-punctured; face and clypeus shining, without microsculpture; frons above antennal cavities roughly wrinkly-punctured to slightly cellular medially; temples smoothly wrinkly-punctured. Face and temples with long sparse pubescense.

T h o r a x: Collar of pronotum from above long with straight front margin; transverse furrow of pronotum shallow, broad; pronotal ridge not swollen, narrow; epomiae sharp, high; pronotal base gradual, sharply curved at the bottom; upper half of pronotum roughly punctured by big punctures. Mesonotum slightly convex, 1,1 times longer than width; notauli in a form of very slight impressions at base; lateral furrow of mesonotum sharp and deep; surface of mesonotum densely punctured by irregular punctures, punctures on middle lobe merged, laterally mesonotum to wrinkly-punctured, surface shining; prepectal carina upwardly not reach pronotum; subalarum thin, high, but not sharpened; speculum roughly wrinkly-punctured as other part of mesopleurae; mesopleural fovea distinctly expressed, area of mesopleural fovea sharply impressed; mesopleural suture straight, very deep, interrupted by very sharp ribs; sternauli sharp and deep up to behind middle of mesopleurae; surface of mesopleurae roughly sculptured, shining; scutellum from lateral moderately elevated above postscutellum, from above slightly convex, laterally not carinated. Hind margin of metanotum with triangular projections opposite of lateral longitudinal carinae. Propodeum from lateral with angular break, length of slightly convex horizontal part equal to length of area posteromedia in middle; carinae of propodeum with exception of costulae sharp, sinuous; costulae slightly marked, coxal carina indistinct, carina closing area dentipara from behind very high; basal area short and deep; area superomedia elongated from rectangular to slightly hexagonal (narrowed backwards), 1,3 times longer than width; areae dentiparae at apices with tooth-like broadenings; spiracles long, slit-shaped, along external contour 3,3 times longer than width. Surface of propodeum, including metapleurae, roughly-wrinkled to cellular, shining, without microsculpture.

L e g s: Slender, long, hind femora narrow, more than 6 times longer than width. Claws very long, slightly uniformly curved.

W i n g s: Areolet big, pentagonal, with narrow base, slightly asymmetrical, external vein of apex shorter than internal one; stigma narrow, dark; radial cell long, radius almost straight; nervulus slightly postfurcal; ramulus long; all veins dark; membrane of wing hyaline. Front wing slightly longer than length of flagellum and shorter than body length.

A b d o m e n:Amblypygous, from above oval, appreciably narrowed backwards from apex of tergite 2, apex of abdomen compressed from sides in different degree, sixth and seventh tergites visible from above on considerable length; second tergite transverse, at apex 1,2 times wider than length; sheath of ovipositor not visible from above. First tergite from lateral with gradual bend between petiolus and postpetiolus, lateral carinae of first tergite smoothed but distinct, from lateral petiolus with transversal ribs especially sharp at upper half; from above petiolus gradually broadened to triangle postpetiolus (at some specimens rather sharply); distance between spiracles some more than distance from spiracles to hind margin of tergite; middle field of postpetiolus distinct, to sharply and high elevated, 1,5 times wider than lateral fields, its surface from longitudinally wrinkly-punctured to sharply striated. Gastrocoeli rather short, superficial, square, 2,3 times narrower than interval with distinct but weak thyridia; lunulae distinct, of moderate size; surface of second tergite up to apex very densely punctured to slightly wrinkled, dull; third tergite densely superficially punctured by very small punctures, other tergites smooth. Hypopygium triangular from lateral, frequently compressed from sides, covered by coarse bristles, but without fascicle of long coarse bristles at apex as at Eutanyacra ; sternites sclerotized slightly, sternites 2-5 with longitudinal fold.

C o l o r a t i o n: Body black with yellow and red pattern; yellow: fronto-vertical orbits, collar of pronotum and scutellum; abdomen predominantly red with black first tergite and apical bands on second and third tergites. Legs, with exception coxae and trochanters I, red.

S i z e: Body length: 11,5; front wing: 10,0; flagellum: 8,7mm.
