Tephritis robusta new species

( Figs 47–51 )

Type material. Holotype Ƥ: AZERBAIJAN, Talysh, Orana vill., Tylykh mt. slope, 13.VI.1981 (Ermolenko) (SIZK).

Paratypes: 3Ƥ, same label as in the holotype, (2Ƥ with abdomen detached, dissected and kept in genital microvials) (SIZK).

Material not included in the type series. Iraq: Samarra, 0 6.1965, 13 (no collector) (NMP).

Etymology. The specific epithet is a Latin adjective meaning robust, strong.

Diagnosis. Tephritis robusta is a moderately big species ( Fig. 47 ) (wing longer than 5 mm) with long ovipositor (oviscape longer than tergites 4–6 combined) similar with T. tatarica , differing from all other large species of the genus, by the combination of reticulate wing pattern with the apical crossband (no apical fork or isolated spots at wing apex). T. robusta differs from T. tatarica by the wing pattern details and AL = / width ratio as given in the key: T. robusta possesses only one pair of small round hyaline spots at anterior part of crossvein r–m (whereas in T. tatarica , crossvein r–m is surrounded by two long yellowish spots formed 2 pairs of fused dots), and its aculeus shorter and wider (7–8 times as long as wide, vs. 11–12 times as long as wide in T. tatarica ). T. robusta occurs in Transcaucasian region, and possibly in Iraq, whereas T. tatarica occurs in mountains of Central Asia from West Siberia to Kyrgyzstan.

Description. Male and female.

Head, thorax and legs. As described T. tatarica .

Wing. ( Fig. 48 ) Cell c with darkened base and brown spot at middle; apex entirely hyaline. Pterostigma and cell r1 as described for T. tatarica ; apex of cell r1 brown. Cell r2+3 hyaline at base, with dark area behind pterostigma. Large hyaline spot proximal to r–m vein level almost rectangular, as long as cell wide and 0.5–0.7 times as wide as hyaline spot anterior to it in r1 cell; dark interval anterior to r–m half as wide as allied hyaline spots; two hyaline spots distal to r–m narrowly connected to distal large spot in cell r1 and widely separated by brown interval from proximal hyaline spot in r1; preapical dark interval (posterior to cell r1 apex) either without hyaline spots or rarely with 1 small round hyaline spot; hyaline spot at apex of cell r2+3 of irregular shape, formed by two confluent round spots with dark incision at wing margin, apex of r2+3 brown.

Cell br hyaline at base, brown in apical half, with large hyaline spot widely connected to large hyaline spot in cell r2+3, and sometimes with small hyaline spot basal to it. Crossvein r–m with one pair round hyaline spots allied to it in br and r4+5. Cell r4+5 at the level of dm-cu with subrectangular hyaline spot, as wide as cell, posterior to narrow dark interval between second and third large spots in r2+3 cell and narrowly connected to them; middle of cell brown with 1–3 small hyaline spots; preapical hyaline spot subrectangular or 8-shaped; apex of cell r4+5 brown, in 25% including small hyaline spot on one wing. Cell m with 4–5 partly merged hyaline spots. Cell dm hyaline at base, with brown medial one-third containing 2–3 hyaline spots or entirely dark; apical one-third of cell with subapical pear-shaped hyaline spot and wide brown apical area, usually including 2–3 hyaline spots. Cell cu with 3–4 hyaline spots in anterior half separated by separate brownish bars, and hyaline posterior part, with 2–3 brownish intervals, only narrowly or not fused. Anal cell with 1–2 dark. Anal lobe hyaline.

Abdomen as described for T. tatarica .

Terminalia. Female. Oviscape as described for T. tatarica , as tergites 4–6 combined. Eversible membrane with two pairs of taeniae 0.25 times as long as membrane itself; membrane with dentate scales, much large medioventrally ( Fig. 51 ). Aculeus slightly shorter than in T. tatarica , 1.9 mm long, 7.75 times as long as wide, with evenly acute apex ( Fig. 50 ). Spermathecae 5.5–6.0 times as long as wide ( Fig. 49 ).

Male as described for female, except genital characters; abdomen not dissected. Measurements. WL = 5.1 mm (Ƥ), 4.9 mm (3); CL = 1.3 mm. AL = 1.9 mm. BL = 7.1 mm (Ƥ). Host plant unknown.

Comments. A malefrom Samarra is the only specimen from the type locality present in the collection, I therefore identify it with some caution and do not include it in the type series.

Diagnosis. Male and female. Tephritis sahandi could be recognized from other Tephritis species by its small size (wing length 2.7–2.9 mm), black femora, banded wing pattern (with oblique band crossing middle of wing from pterostigma through crossveins r–m and dm-cu, combined with an irregular subbasal spot leaving costal cell and anal lobe hyaline, and a short triangular accessory spot at the middle of cell r1) ( Fig. 53 ) and the subshining, black setulose abdomen, with tergite 5 of male and tergites 5–6 of female shining black and dorsal surface of oviscape only black setulose.

Diagnosis. Male and female. T. sinica could be recognized from other Tephritis species by its banded wing pattern (Fig. 54) (with five brownish-yellow anteriorly separated straight crossbands: discal crossband from pterostigma to CuA2+A1 apex, and two medial crossbands from cell R1 separately through r–m and dm–cu fused at posterior margin forming inverted Y-like fork, one preapical and short apical crossband). Oviscape reddish-yellow, as long as tergites 4–6 combined. Phallus glans as on Fig. 55. Wing length 5.0– 6.1 mm. See Wang (1990, 1998) for more detailed description.

Comments: Type material from Nei Mongol ( China, IZAS), was not available for examination and I refer to the descriptions by Wang (1992-1998).
