Elevation range in Mongolia . Adults were collected at altitudes ranging from 1100 m to 1500 m . Period of activity. Adults are active from late May through to late June. Known distribution. China , Mongolia ( Map 11 ) and Russia (Far East). Redescription. Male. Body length 11.3–14.7 mm , wing length 11.6–14.9 mm . General body coloration yellowish gray. FIGURES 142–148. Hypopygium of male T. ( Vestiplex ) pallitergata . 142. Tergite 9, dorsal view; 143. Gonocoxite, lateral view; 144. Left outer gonostylus, lateral view; 145. Left inner gonostylus, lateral view; 146. Gonocoxal fragment (medial sclerites), dorsal view; 147. Aedeagal guide, ventral view; 148. Sperm pump, dorsal view. Head . Brownish gray, vertex and occiput gray with brown median line. Rostrum brownish yellow with conspicuous nasus. Antenna 13-segmented, if bent backward reaching beyond base of abdomen. Scape, pedicel and flagellomere 1 yellow, flagellum bicolorous. Each flagellomere except first one with darkened basal enlargement and strong incision. Apical flagellomere very small, distinctly shorter than preceding flagellomere. Verticils shorter than corresponding segments. Palpus brownish yellow. Thorax . Yellowish, dusted with gray. Pronotum light brown with brown median line. Prescutum and presutural scutum yellowish gray pruinose with 4 longitudinal stripes bordered by brown. Intermediate pair light brown, separated medially and fused posteriorly and anteriorly. Lateral stripe gray. Interspace between median and lateral stripes light brown. Postsutural scutum light brown, scutal lobe with spot bordered by brown. Scutellum and postnotum yellowish with brown median line. Pleura yellow, sparsely dusted with gray. Coxae yellowish, sparsely dusted with gray. Trochanters yellow. Femora and tibiae yellow. Tarsal segments brown. Distal part of femora darkened, distal part of tibiae broadly darkened. Tarsal claws without tooth. Wing with ground color pale brown.

Sternite 8 with hypovalvae, ventral view; 151. Sternite 9, furca and bursa copulatrix, dorsal view. Scale of 149 = 0.8 mm, 150–151 = 0.5 mm. Abdomen . Yellow, with brown dorsal stripe and narrowly interrupted lateral stripe. Lateral margins of tergites pale. Tergite 1 laterally sparsely dusted, succeeding tergites yellow. Abdominal sternites sparsely dusted with gray. Hypopygium . Yellow. Tergite 9 forming pale yellow relatively narrow plate ( Fig. 142 ). Main body of tergal plate pale yellow. Posterior margin of tergal plate broadly emarginated with small median incision, posterior lobes rounded, provided with long setae. Anterior portion brown with raised border appearing as small transverse elevated saucer with margin narrowly blackened. Saucer short, about 4.3 times as wide as long whole tergal plate. Gonocoxite ends with straight spine, apex gently curved and blackened ( Fig. 43 ). Outer gonostylus nearly oval with basal part narrowed ( Fig. 144 ). Inner gonostylus in shape of lightly curved plate, dorsally with sharp spine, beak extended into obtuse rostrum ( Fig. 145 ). Gonocoxal fragment ( Fig. 146 ) with medial sclerites slender, posteriorly slightly dilated, anteriorly fused into base, together forming V-shaped structure. Lateral sclerite generally as in T. ( V. ) scripta but with conspicuous inner lobe ( Fig. 7 ). Aedeagal guide forming cone-shaped semi open groove with narrow apex ( Fig. 147 ). Sperm pump with central vesicle slightly flattened ( Fig. 148 ). Compressor apodeme with median incision. Posterior immovable apodeme much longer than compressor apodeme, flattened. Anterior immovable apodeme nearly triangle with nearly straight anterior margin. Aedeagus shaped as elongate tube, about 6.2 times as long as sperm pump, basal part brown, rest yellow, distally passing into pale yellow. Female. Body length 16.9–18.0 mm, wing length 11.2–12.2 mm . Antenna of reaching prescutum if bet backwards, flagellomeres cylindrical and bicolorous. Ovipositor ( Figs 149–151 ). Tergite 10 shiny yellow. Cercus yellow, shorter than tergite 10, straight, distal part narrowed, outer margin with rough serration ( Fig. 149 ). Hypovalva in shape of relatively short, yellow filament, with long trichia at tip ( Fig. 150 ). Median incision between hypovalvae approximately at same level as posterior margin of sternite 8. Sternite 9 posteriorly with slender and obtuse apex ( Fig. 151 ). Two small posterior extensions on either side beneath apex. Furca anteriorly long and narrow, posteriorly broad. Bursa copulatrix and spermathecal ducts without sclerotisation. Spermatheca spherical ( Fig. 16 ).
