Diagnosis. Tephritis tatarica is a moderately large species that differs from all other species of the genus, except T. robusta, by the combination of wing pattern reticulate with the apical crossband instead of apical fork or isolated spots, and wing length more than 4.8 mm and female oviscape longer than tergites 4–6 combined. T. tatarica most reliably differs from T. robusta by the wing pattern details and AL = / width ratio as given in the key: T. tatarica has the crossvein r–m surrounded by two elongate yellowish spots formed by fusion of 2 pairs of spots (rather than one pair of round hyaline spots at anterior part of r–m in T. robusta), and its aculeus longer and narrower (11–12 times as long as wide, vs. 7–8 times as long as wide in T. robusta).
Description. Male and female.
Head. Yellow; length: height: width ratio 1: 1.1: 1.4. Frons as wide as long. Eye 1.4 times as high as long. First flagellomere of antenna 2.1 times as long as wide. Gena 0.5 times as high as length of first flagellomere. Ocellar, medial vertical, anterior orbital and frontal setae black; other setae, including posterior orbital and lateral vertical, white. Postocular and genal setulae black and white and setulae on distal part of palpus and on pedicel black.
Thorax. Ground colour black, dense grey microtrichose; median part of postpronotum, narrow areas on dorsal part of anepisternum, dorsal half of greater ampulla, small adjacent sclerites and postscutellum yellow. Scutellum black, grey microtrichose, yellow at sides, grey microtrichose with several whitish setulae. Most setae black and acuminate; posterior notopleural seta whitish and lanceolate; anepisternal seta and anepimeral seta black. Apical scutellar seta half as long as basal seta. Calypters white, with whitish fringe; upper calypterconspicuously lobate, almost as long as wide, ventral clypter narrow. Halter yellow.
Legs. Coxae yellow. Femora yellow with yellowish brown and white setae. Tibiae yellow. Tarsi yellow.
Wing. (Fig. 57) Cell bc hyaline, pale brownish at apex. Cell c with darkened base and brown spot at middle, its apex entirely hyaline. Pterostigma brown, except narrow triangular yellowish or hyaline area along costal vein at apex. Cell r1 apical to pterostigma brown with two subrectangular hyaline spots separated by dark interval 0.5 times as wide as distal spot; r1 dark at the top. Cell r2+3 hyaline at base, with dark area posterior to pterostigma. Large hyaline spot proximally to r–m vein level almost rectangular, as long as cell width and 0.5–0.7 times as wide as hyaline spot anterior to it in r1 cell; it, and two hyaline spots distally to r–m separated by dark intervals half as wide as hyaline spots; three rectangular hyaline spots in medial part of r2+3 cell conspicuously touching (or confluent with) hyaline spots anterior to them in cell r1 and posterior to them in cells br and r4+5. Subapical dark interval (posterior to cell r1 apex) either without hyaline spots or with 1–2 small round hyaline spots; hyaline spot at r2+3 apex of irregular shape, formed by two usually partly confluent round spots (rarely separate) with dark incision between them at wing margin; apex of r2+3 dark. Cell br hyaline in basal half, dark posterior to pterostigma usually with 2 small round hyaline spots, one larger, elongate hyaline spot distally to R1 apex level; crossvein r–m bordered by two pairs of hyaline or yellowish dots normally fused and forming narrow hyaline spots at each side, rarely in males with one round dot anteriorly at each side. Cell r4+5 with narrow trapezoidal or subrectangular spot at the level of dm-cu, as wide as cell and located posterior to narrow dark interval between second and third large spots in r2+3 cell; wide dark spot in the middle of cell, at level of r2+3 apex, with 2–3 small hyaline spots; subapical hyaline spot rectangular or 8-shaped, separating dark apex.
Subapical dark interval with hyaline spots in r2+3 and r4+5 cells forming more or less distinctive subapical band. Apical crossband with angulate proximal margin, entirely brown, sometimes including round hyaline spot on one or, very rarely, on both wings.
Cell m with 3–5, partly fused hyaline spots, basal touching or fused with large spot in r4+5 cell. Cell dm hyaline at base, with dark area in medial one-third, with 3–5 hyaline spots or entirely dark; apical one-third of cell with subapical pear-shaped hyaline spot and wide brown apical area, usually with 2 hyaline spots. Cell cu with 3–5 hyaline spots in anterior half separated by partly fused brownish bars, and hyaline posterior part, with 2–3 brownish intervals, forming distinctive reticulate appearance. Anal lobe with dark spots anterior to A2 vein but not reaching anal lobe.
Base of wing hyaline, costal cell with dark spot in middle. Base of cell br, basal half of cell r2+3 almost whole cell bm, apex of cell bcu and area along vein CuA 1 in basal halves of cells dm and cua with irregular brown spot. Pterostigma (apical portion of subcostal cell) brown without hyaline spots. Oblique brown stigmal crossband crossing wing from pterostigma through r–m and dm-cu to posterior margin and joined with basal spot through basal portions of cells r1 and r2+3. Subapical band crossing wing from apex of r1 cell to middle of posterior margin of cell m. Apical band crossing wing between middle of R2+3 to R4+5 distance to apical quarter of cell m, with proximal margin arcuate or almost straight. In addition, cell r1 with brown triangular indentation at the level of dm-cu and proximal to subapical crossband, isolated or partly fused to it. Distance between crossveins r–m and dm-cu as long as r–m.
Abdomen. Ground colour black, covered with microtrichose. Abdominal tergites white setulose and setose. Sternites black, brown setose and setulose moderately wide, male sternite 5 posteriorly incised. Female sternite 6 with anteromedial apodeme. Abdominal pleura matt black or grey.
Terminalia. Male. Epandrium (Figs 58–59) of oval shape common to other Tephritis species. Phallus without spines, glans (Fig. 60) moderately short, mostly membranous. Ejaculatory apodeme on Fig. 61.
Female. Oviscape black, sometimes redish brown, entirely black setulose and setose, longer than tergites 3-6 combined. Eversible membrane with two pairs of taeniae 0.3 times as long as membrane itself; membrane with dentate scales equal size (Fig. 64). Aculeus long, 2.1 mm long, 11.5 times as long as wide, with apex slightly incised (Figs 62–63). Two short, papillose spermathecae 4.0–4.5 times as long as wide (Fig. 65).
Measurements. WL = 5.3–5.5 mm (n=5) (3), 6.4–6.5 mm (n=5) (Ƥ); CL = 1.5 mm. AL = 2.1 mm. BL = 5.2–5.6 mm (n=5) (3), 7.9–8.2 mm (n=5) (Ƥ).
Host plant. Alfredia nivea Kar. et Kir.
