Scape and pedicel yellow, first flagellomere yellow, darkened brown mesally. Flagellomeres 2–6 brownish, succeeding flagellomeres yellowish, apical flagellomere brownish, small, reduced, distinctly shorter than preceding flagellomere. Each flagellomere, except first, with darkened basal enlargement and moderately incised. Verticils shorter than respective segments. Palpus brown. Thorax . Brownish gray.

Scales of 58 = 0.8 mm, 59–62 = 0.5 mm. Hypopygium . Brown, at base slightly broader than abdomen. Tergite 9 in shape of large concave crescent sclerotised saucer ( Fig. 50 ). Main body of tergal saucer brownish yellow with blackened rim. Posterior margin of tergal saucer broadly emarginated, with small denticles or teeth. Median V-shaped notch inconspicuous. Lateral angle of tergal saucer with broad obtuse tooth. Anterior and lateral portions of tergal saucer raised into sclerotised border. Border anteriorly inconspicuously toothed, laterally produced into acute tooth directed caudad and situated under lateral angle of tergal saucer so tergite 9 with 2 teeth in lateral view. Gonocoxite unarmed ( Fig. 51 ). Outer gonostylus flattened, nearly oval ( Fig. 52 ). Inner gonostylus in shape of claw-shaped plate, with 2 mid-dorsal teeth, anterior tooth twice as large as posterior. Beak extended into blackened, obtuse rostrum ( Fig. 53 ). Gonocoxal fragment large with lateral and medial sclerites well-developed ( Fig. 54 ). Medial sclerites fused, anterior apodeme long and broad, posterior part flat and arched. Lateral sclerite large and bilobed. Aedeagal guide in shape of long, slender tube ( Fig. 55 ). Sperm pump with central vesicle small and flattened ( Fig. 56 ). Compressor apodeme with median incision. Posterior immovable apodeme much longer than compressor apodeme, large and extended laterally into broad plate. Anterior immovable apodeme in shape of rounded plate. Aedeagus shaped as very long tube similar to T. ( V. ) subcentralis . Distal part ventrally membranous, shovel-shaped ( Fig. 57 ). Female. Body length 26.8–27.0 mm, wing length 22.0– 26.6 mm . Antenna short, flagellomeres except first with very small incisions. Mesopleura brown, gray pruinose. Distal part of femora darkened. Ovipositor ( Figs 58–62 ). Tergite 10 shiny, brown. Cercus brownish yellow, slender, about as long as tergite 10, with tip narrowed, outer margin almost smooth with small serration ( Fig. 58 ). Hypovalva in shape of pale, elongated slender filament, with short trichia at tip ( Fig. 59 ). Median incision between hypovalvae deeper than posterior margin of sternite 8. Lateral incision relatively deep and narrow (about twice as deep as maximal width). Lateral angle of sternite 8 rounded. Sternite 9 with anterior part slightly broadened, posterior part rounded ( Fig. 60 ). Furca anteriorly narrowed, posteriorly broad ( Fig. 61 ). Bursa copulatrix with spermathecal ducts sclerotised at base, in shape of lightly curved, slender dark brown process. Wall of bursa copulatrix on connection site with spermathecal ducts partially sclerotised, sclerotisation extended short distance along wall ( Fig. 62 ). Cul-de-sac of bursa copulatrix curved. Spermatheca spherical, greatly broadened at base ( Fig. 25 ). Remarks. An endemic species for Mongolia .
