Surface of clypeus densely punctured by smoothed punctures of moderate size, middle field with more deep rough and big punctures, lateral fields wrinkly-punctured; frons above antennal cavities roughly transversely wrinkled; vertex and temples longitudinally wrinklypunctured, striation of vertex sharp; surface of head without microsculpture. Frons, face and temples in lower half with long darkened pubescence (more short than in T. gobiensis nov.sp.).

T h o r a x: Collar of pronotum from above short, with more or less straight front margin; transverse furrow of pronotum very deep; pronotal ridge not swollen; epomiae sharp, high; lateral surface of pronotum with rough sculpture and slight shine; pronotal base gradually curved, slightly sinuous. Mesonotum moderately convex, some (1,2 times) longer than width; notauli only just marked at base, practically absent; lateral furrow of mesonotum deep; surface of mesonotum densely punctured with more big smoothed punctures on middle lobe, without microsculpture, shining; axillary tongue distinct; prepectal carina at upper part not reach pronotum; subalarum high, not sharpened; speculum strongly convex with big punctures; mesopleural fovea sharply expressed, deep, without longitudinal impression around; mesopleural suture straight, deep, interrupted by sharp ribs; mesopleurae at bottom with bend from lower third before sternauli; sternauli in a shape of broad triangular impression up to hind third of mesopleurae; mesosternal suture deep, not strongly broadened backwards; surface of mesopleurae on the larger part roughly-wrinkled to cellular at lower third, dull or with slight shine; scutellum from lateral moderately elevated above postscutellum, from above almost flat, laterally not carinated, its surface punctured by smoothed punctures. Hind margin of metanotum with strong triangular projections opposite of lateral longitudinal carinae. Length of horizontal part of propodeum 1,9 times less than length of area posteromedia in middle; carinae of propodeum with exception of costulae and coxal carinae sharp; basal area short and deep; area superomedia rectangular, slightly transverse; all carinae of horizontal part high and sinuous; areae dentiparae at apex with strong teeth (more narrow than in Triptognathops gobiensis nov.sp.); spiracles long, slit-shaped, along external contour 4 times longer than width at middle. Surface of propodeum, including metapleurae, roughly-wrinkled, without microsculpture; vertical parts of propodeum with dark, rather sparse pubescence.

L e g s: Slender and long, hind tarsi long and slender. All tibiae with long thin spinules, all tarsi with dense spinules ventrally; first segment of hind tarsi compressed from sides. Hind coxae elongated. Claws very narrow and long, slightly uniformly curved.

W i n g s: Areolet pentagonal, big with narrow base, practically symmetrical, external vein of apex shorter than internal one; stigma rather broad, long, dark; radial cell long; radius slightly curved; nervulus slightly postfurcal; ramulus rather long; all veins dark; membrane of wing darkened. Front wing 1,1 times longer than length of flagellum and 1,3 times shorter than body length.

A b d o m e n: Amblypygous, from above broad rather strongly narrowed to apex, apical tergites not hidden, sheath of ovipositor from above not protrude; second tergite transverse, at apex 1,4 times wider than length in middle. First tergite from lateral with distinct smoothed bend between petiolus and postpetiolus, from lateral sharply bordered by carinae and with strong transversal ribs between them; from above petiolus sharply broadened to postpetiolus, rectangular behind spiracles; distance between spiracles 1,8 times more than distance from spiracles to hind margin of tergite; middle field of postpetiolus sharply expressed and high elevated, more than 2 times wider than lateral fields, its surface roughly longitudinally striated, lateral fields of postpetiolus also with longitudinal wrinkles. Gastrocoeli small, only just impressed and approached to base of second tergite, many times narrower than interval between them; thyridia absent; lunulae weak, of moderate size; interval between gastrocoeli and surface of second tergite very densely and indistinctly superficially punctured, more densely in middle, with slight shine; tergite 3 shagreen. Only sternite 2 only just visible less sclerotized than subsequent ones; only sternites with sparse short pubescence.
