Diagnosis. Tephritis kogardtauica can be easily separated from other Palaearctic species of Tephritis by the combination of pale yellowish grey wing pattern, entirely brownish yellow pterostigma without hyaline spot, and 2 separated spots at the the apices of veins R 4+5 and M, 2 hyaline spots in r 1 cell, cell r 2+3 with hyaline spot basal of rm level, cell r 4+5 with large subquadrate hyaline spot in basal half, oviscape widely white setulose and aculeus long and wide, evenly narrowed towards apex and narrowly rounded at apex, without steps or incisions. Thorax and abdomen are densely yellow-grey microtrichose, white setulose. Overwintered females differ by having black oviscape, whereas freshly-reared flies of the summer generation have mostly brownish yellow oviscape. This species is associated with Inula macrophylla and I. stenocalathia .

Description. Head: As described for T. bardanae (see Korneyev et al. (2015) for details).

Thorax and legs: As described for T. hendeliana , ground colour of scutum and scutellum brown to black, densely ochreous-grey microtrichose (golden yellow in fresh specimens). Apical scutellar seta 2/3× as long as basal scutellar seta. Legs entirely yellow to brownish yellow. Fore femur with 2 posterodorsal rows of shorter white setae and 1 posteroventral row of long yellowish brown setae, midfemur white setulose on anterior surface and yellowish brown on the rest.

Wing ( Figs 20b – d ): With pale yellowish grey pattern. Cells bc and c hyaline. Pterostigma brown or yellowish brown, without hyaline spots. Cell r 1 posterior to pterostigma brownish yellow, 2 trapeziform hyaline spots distal to R 1 apex separated by narrow brown bar; apex of cell r 1 entirely brownish yellow. Cell r 2+3 hyaline at base, yellowish grey posterior of pterostigma; 3 hyaline spots separated by narrow yellow bars posterior to hyaline spots in r 1 forming hyaline M-shaped mark, medial spot 2–3 × as wide as proximal and distal spots. Preapical brown area (posterior to cell r 1 apex) with 2–4 smaller hyaline or pale grey spots. Apex hyaline with small triangular dark spot at apex of R 4+5 vein. Cell br hyaline in basal half and pale grey in apical half, usually with 2 small round hyaline spots. Crossvein r-m in a dark field with 4 faint, paler dots usually fused and forming narrow pale grey, yellow or hyaline vertical bars at both sides of crossvein. Cell r 4+5 at dm-cu level with large subquadrate hyaline spot largely fused with hyaline spot in r 2+3 but clearly isolated from hyaline spots in cells dm and m;, middle third of cell r 4+5 with pair of round spots or narrow hyaline spot either isolated, touching or fused with hyaline spot in cell r 2+3; and with yellowish grey area in distal half of cell without or at most with 1–2 pale yellowish, rarely hyaline dots; apex with small triangular dark spots on R 4+5 and M apices. Vein R 4+5 ventrally with 11–13 setulae. Cell dm with hyaline base and 2 grey or yellowish grey bars separated by large round or pear-like hyaline spot; apex of dm entirely greyish yellow or with 1–3 yellow or hyaline dots or small spots. Cell m with brownish base, isolated or open round hyaline spot at anterobasal margin and variously developed greyish yellow pattern of fused or isolated bars often not reaching its posterior margin. Cell cua hyaline at base and with 3 separated greyish bars in its medial part, entirely hyaline posterior half, and greyish apex. Anal cell with pale-yellow or grey spot aligned with vein Cu 2 +A 1. Anal lobe entirely hyaline.

Abdomen ( Fig. 20a ): Abdominal tergites black or partly yellow; densely microtrichose, white setulose and setose; male tergite 5 and female tergites 5 and 6 with brown to black marginal setae. Sternites brown to black, white setulose, moderately wide, male sternite 5 posteriorly incised. Female sternite 6 with anteromedial apodeme. Abdominal pleura matt yellowish brown, grey or black.

Terminalia: Male. Epandrium and glans ( Fig. 21e ) similar to other Tephritis species. Female. Oviscape reddish yellow (in summer generation) to black (in overwintering generation), longer than 4 posteriormost abdominal tergites combined but shorter than abdomen, widely white setulose ventrally and on anterolateral corners dorsally, brown or yellow setulose and setose dorsomedially and posteriorly ( Fig. 20a ). Eversible membrane with 2 pairs of taeniae 0.25 × as long as membrane itself; membrane with dentate scales, anteromedially large and blunt ( Fig. 21b ). Aculeus 4.5× as long as wide, with evenly acute apex ( Figs 21a, c ). 2 moderately long, papillose spermathecae 4× as long as wide ( Fig. 21d ).

Measurements: Female. BL= 7.2–7.9 mm (n=10); WL= 5.2–6.2 mm (n=5), C2= 1.2–1.3 mm; AL= 2.1–2.2 mm; C2/AL = 0.57–0.62 (n=5). Male. BL= 5.8–6.5 mm (n=5); WL= 5.1–6.1 mm (n=5).

Host plant. The larvae feed in flower heads of Inula macrophylla Kar. et Kir. (= Inula grandis Schrenk ex Fisch. & C. A. Mey ) in Kyrgyzstan, Uzbekistan and Tajikistan) and Inula stenocalathia (Rech. f.) Soldano (= Codonocephalum stenocalathium Rech. f.), in Iran ( Korneyev et al. 2015a).

Distribution. Azerbaijan, Iran, Kazakhstan, Kyrgyzstan, Tajikistan, Uzbekistan ( Korneyev et al. 2015a).

Remarks. Tephritis kogardtauica occurs in the lower and middle belt of mountains, from 900 to 2600 m a. s. l. on ungrazed grasslands, often on steep slopes filled mainly by Serratula or Saussurea spp. ( Asteraceae ), and with Inula spp. plants as subdominants.
