Paratypes: KYRGYZSTAN: 13: Kichik-Alai Ridge, Isfairam-Sai basin, 45 km S of Kyzyl-Kiya, 39°48.7'N 72°06'E, h= 2800–3000 m; 05.VII.1999; 1Ƥ: same locality, 39°48.7'N 72°06'E, h= 2900 m, 26.VII.1999, swept from Cousinia sp. (Kameneva & Korneyev) (SIZK). TAJIKISTAN: 23, 1Ƥ: Western Pamir, Upper Gunt Vy., Dzilandy, 3670 m, subalpine steppe, swept from Cousinia calathidia [=flower heads], 18.IX.2002 (Dickore) (ZHB); AFGHANISTAN: 1Ƥ: Bamian, Bende-Amir, 3100 m, 3.VIII.2011 (Plusch) (SIZK).

Etymology. Species name gladius is the Latin noun in apposition (meaning ancient Roman sword) and reflects the shape of its aculeus.

Diagnosis. The new species is very similar to T. angulatofasciata and T. cameo , sharing the angulate banded wing pattern, but is different from both species by the shorter oviscape (as long as abdominal tergites 5 and 6 combined), from T. angulatofasciata by smaller size, and from T. cameo by evenly curbed sides of aculeus without angulate latero-apical shoulders (see the key below).

Description. Male and female.

Head, thorax and legs. As in T. admissa .

Wing. ( Fig. 33 ) Cell c darkened at base, with hyaline apex, or entirely darkened. Pterostigma brown. Cell r1 apical to pterostigma brown with two wide subrectangular hyaline spots separated by dark interval 0.8–1.1 times as wide as basal spot; apex of cell r1 dark without additional hyaline spot. Cell r2+3 hyaline at base, with brown spot posterior of pterostigma; hyaline spot proximal to r–m vein level rectangular and as wide as cell, widely connected to hyaline cells anterior and posterior to it; hyaline spot distal to r–m wide, preapical brown area (posterior to cell r1 apex) without hyaline spots; preapical hyaline spot (distal to apex of vein R2+3) usually wide and single; apex of r2+3 dark.

Cell br hyaline at basal half, with 2 brown areas in apical half separated by large subrectangular hyaline spot. Crossvein r–m widely brown bordered, without hyaline spots. Cell r4+5 at level of dm-cu with subrectangular hyaline spot as wide as cell and widely connected to hyaline spot in cells r2+3 and m and rectangular or 8-shaped subapical hyaline spot. Apical crossband as in T. admissa , could be narrowly connected with preapical crossband along vein M or almost connected through medial portion of cell r4+5. Cell m with two unequal hyaline spots, basal long subrectangular or 8-shaped, widely touching to large spot in r4+5 cell, preapical hyaline spot smaller, joined with hyaline spots in r2+3 and r4+5 cells into preapical hyaline crossband, and separating brown apical crossband. Cell dm with hyaline base distally and subrectangular spot proximal to vein r–m level, connected with hyaline areas in cells br and cu forming entire hyaline crossband, and equal to entirely brown areas proximal and distal to it; only distal brown area very rarely including round hyaline dot. Cell cu with 2 large brown spots, at apex and at middle, both as wide as cell and sepearated by subequal hyaline cell; basal spot at CuA2 and A1 junction large, often joined to medial brown spot along vein CuA1 and extending into anal cell. Wing dark and hyaline spots joined into 4 almost regular parallel crossbands separated by subequal hyaline intervals. Anal lobe hyaline or sometimes with 1–2 isolated brown spots.

Abdomen. Ground colour brown, grey microtrichose, as described for T. admissa .

Terminalia. Male. Epandrium and phallus glans similar to those in T. cameo . Female. Oviscape shining black, as long as tergites 4–6 combined. Eversible membrane, with taeniae 0.3–0.35 times as long as whole eversible membrane; and dentate scales (long and sharp), large medioventrally ( Fig. 35 ). Aculeus moderately short, 1.1 mm long, 4.3 times as long as wide, with evenly acute apex. ( Fig. 34 ). Two papillose spermathecae 5.5–6.0 times as long as wide ( Fig. 36 ).

Measurements. WL = 4.0– 4.3 mm (3), 4.1–4.4 mm (Ƥ); CL = 1.1 mm. AL = 1.1 mm. AL/CL = 1. Body length, 4.9–5.1 mm (3), 5.5–5.7 mm (Ƥ).

Host plants. Very probably, Cousinia sp.
