Description.

Head (fig. 3): Yellow, whitish microtrichose, except ocellar triangle, distal 2/3 of arista and V-shaped mark on upper part of occiput blackish. Flagellomere 1 yellow. Frontal stripe and face less distinctly microtrichose; frons above lunule with 5–10 setulae. Setulae whitish-yellow, brownish on anterior part of gena. Postocular setae and setulae (both longer and shorter) whitish-yellow. Length: height: width ratio = 1: 1.24: 1.57. Frons subquadrate, twice as wide as eye, which is about 1.35 times as high as long. Gena 0.47 times as high as length of flagellomere 1. Flagellomere 1, 1.6 times as long as wide, pointed at apicodorsal angle.

Thorax: Black (only postpronotal lobe narrowly yellow), densely white microtrichose (fig. 9). Setae yellowish brown; posterior notopleural and anepimeral seta dark yellow. Setulae white; scutellum with 15–17 white marginal setulae on each side. Calypteres white. Halter yellow.

Legs: Yellow, fore femur with 2 rows of white posterodorsal and one row of yellowish brown posteroventral setae; mid and hind legs with brown setae and setulae.

Wing ( Figs. 1–2 , 11 ): Base hyaline, including all of cells c, bm and bcu; apical portion with brown radiate mark, with few hyaline spots and indentations; pterostigma entirely brown, cell r 1 in females and 2 males with only one hyaline spot (In females this spot is smaller and reaching to vein R2+3 but in males is larger and penetrates to at most mid-width of cell r2+3) but in the remaining 2 males with 1 additional small hyaline spot on anterior margin (in one male the small hyaline spot is near the larger spot; in another it is closer to the apex of R2+3); cell r2+3 hyaline between radial fork and level of apex of vein Sc, distally brown, with 2 apical hyaline spots, the posterior fused with subapical spot in cell r4+5; br hyaline between basal part of cell and level of apex of Sc, in apical third completely dark, without hyaline spots; cell r4+5 with round hyaline spot touching vein M at or near level of dm-cu, and apical spot rather long, bordered by 2 narrow apical rays extending to apices of veins R4+5 and M; cell dm hyaline on proximal half, on apical half with anterodistal corner dark brown and with 2–3 brown rays (including 1 on dm-cu) and 1 pear-shaped or in some paratypes 2 smaller round subapical hyaline spots; the short brown ray in cell dm basal to level of r-m absent (two males) or usually reaching only mid-width of cell dm, rarely (one female) reaching to vein Cua1. Cell m with 3 large hyaline spots, the most distal extending into cell r4+5; cell cua1 mostly hyaline, with dark apex with small hyaline spot narrow brown bars in apical half. Vein R4+5 with 4–5 setulae ventrally.

Abdomen: Black, tergites entirely microtrichose, with white setulae and yellow marginal setae. Oviscape shining black, with whitish setae on basal part; shorter than tergites 5 and 6 combined, its dorsum 1.36 times as long as tergite 6 ( Fig. 11 ). Aculeus brown, 3 times as long as wide, rapidly tapered subapically to short, pointed apex ( Figs. 4–5 ). Spermathecae teardrop shaped ( Fig. 8 ) round with narrowed neck. Epandrium oval, like other Tephritis species ( Fig. 6 ); glans ( Fig. 7 ) moderately short, mostly membranous.

Measurements. Female. Body length 3.7–4.4 mm, wing length 3.75–4 mm, oviscape length 0.75–0.87; Male. Body length 3.7–4 mm, wing length 3.5–4 mm.

Diagnosis. The new species differs from most Palaearctic species of Tephritis by having only one marginal hyaline spot in cell r1 or if 2, the second spot very small. T. azari sp. nov. is closely related to T. maccus Hering 1937 ( Fig. 13 ) in having similar body, wing size and wing pattern (hyaline basally, with brown radiate pattern on apical two-thirds, and usually with one hyaline spot in cell r1, as well as flagellomere 1 pointed, oviscape short, aculeus relatively blunt, with short acute apex and similar spermathecae shape. It differs from T. maccus by the short brown ray in cell dm basal to the level of r-m, absent or usually reaching only mid-width of cell dm, at most reaching Cu1 (long, reaching middle of cell cua 1 in T. maccus ). In addition in both sexes of T. azari there is a large hyaline spot present in cell r4+5 at the level of dm-cu (in T. maccus only males have such a spot).

Tephritis azari is also similar to T. urelliosomima ( Figs. 14–15 ), in which the aculeus shape is similar (blunt, but pointed at very apex). It differs in wing pattern with a hyaline spot in cell r1 and the apical fork narrowly connected to the main pattern (in T. urelliosomima the large hyaline spot in r1 is lacking and the base of the apical fork is broadly connected to the main part of the pattern).

Etymology. Azari , also known as Old Azeri (also spelled Adari, Adhari), is an ancient language of the Iranian group spoken in the Iranian Azerbaijan; the species name is considered a Latinized noun in apposition.
