Etymology. The specific epithet is a Latinised compound adjective derived of Greek ωχρός, pale, ochreous and πτερό, wing, feather meaning ochreous-winged; it is referring to its pale, yellowish or brownish grey wing pattern.

Diagnosis. Tephritis ochroptera can be readily differentiated from all known species of the genus Tephritis by the combination of the pale wing pattern with the mushroom-like grey spot at apex (instead of apical fork or 2 isolated spots) and largely confluent hyaline spots. In the group of species with entire apical spot or crossband, it is similar to T. afrostriata in its pale wing pattern, cell r1 with two large spots and a small (additional) hyaline spot at its apex, and in abdominal tergites and oviscape at least partly yellow, clearly differing by the hyaline spots around crossveins r–m and dm-cu large and widely confluent; there is no grey crossband between pterostigma and crossvein dm-cu, typical for T. afrostriata .

Description. Male and female.

Head. Entirely yellow, length: height: width ratio 1: 1.1: 1.4. Frons as wide as high. 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. Setae as described for T. admissa .

Thorax. Ground colour black, densely silvery microtrichose; median part of postpronotum, narrow areas on dorsal part of anepisternum, dorsal half of greater ampulla and small adjacent sclerites and postscutellum yellow. Scutellum entirely yellow, grey microtrichose and white setulose. Most setae yellowish brown; posterior notopleural seta white and lanceolate; anepisternal and anepimeral seta yellow. Apical scutellar setae half as long Wing. ( Fig. 35 ) Wing with ochreous grey to pale brown washed cellular pattern. Costal cell hyaline or at most with small pale brown spot at middle. Pterostigma brown without hyaline spots, narrowly yellowish along anterodistal margin. Cell r1 posterior to pterostigma dark colored, often with 1-3 ochreous spots, apically to vein R1 apex with two wide large hyaline spots separated by dark interval 0.25 times as wide as distal spot; at apex of r1 brownish grey, sometimes with small additional hyaline spot. Cell r2+3 hyaline at base, with narrow dark area posterior to pterostigma; hyaline spot proximally to r–m vein level round or oval, as wide as cell. 0.3 times as wide as hyaline spot anterior to it in r1 cell; dark interval anterior to r–m narrow, conspicuously narrower than hyaline spot basal to it; large hyaline spot in cell r2+3 distal to r–m level twice as wide as hyaline spots basal and distal to it and widely confluent with hyaline spots anterior and posterior to it; preapical dark interval (posterior to cell r1 apex) with 0-4 small ochreous spots in it and often wit hyaline spot allied to vein R2+3 apex; hyaline spot at r2+3 apex of irregular shape, either separated or confluent with latter spot; apex of cell r2+3 narrowly grey or brown.

Cell br hyaline in basal half, with pale browh with 3-4 hyline spots posterior to pterostigma; crossvein r–m with four isolated hyaline spots, sometimes fused into 2 bar-like spots. Cell r4+5 at level of dm-cu with large hyaline spot, as wide as cell; medial portion of cell wide pale brown area including 1-5 small hyaline spots and separated by 8-shaped hyaline spot and from dark apex of cell r4+5 (sometimes connected to it by narrow bridge). Apical spot (apical crossband pale brown or ochreous grey, sometimes including 1-3 pale grey dots.

Cell m with 4 hyaline spots separated by narrow pale brown intervals or partly confluent. Cell dm hyaline at base, with 4-6 hyaline spots separated with narrow pale grey intervals. Cell cu and anal cell with narrow pale grey areas connected ino loose grid or separated. Anal lobe hyaline.

Abdomen. ( Fig. 44 ) Tergites brown with yellow margins, grey microtrichose, otherwise as described for T. afrostriata .

Terminalia. Male. Epandrium ( Figs 39–40 ) of oval shape common to other Tephritis species. Phallus without spines, glans ( Fig. 41 ) moderately short, mostly membranous. Ejaculatory apodeme on Fig. 42 . Female. Oviscape brownish-yellow, otherwise as described for T. afrostriata , as long as tergites 4-6 combined. Eversible membrane with two pairs of taeniae 0.35–0.4 times as long as membrane itself; dentate scales uniformly small, not enlarged medioventrally ( Fig. 45 ). Aculeus moderately short, 5.6 times as long as wide, with evenly pointed apex ( Fig. 44 ). Two papillose spermathecae 3.8-4.2 times as long as wide ( Fig. 46 ).

Measurements. WL = 3.7–4.0 mm (n=10) (3), 3.9–4.2 mm (n=10) (Ƥ); CL = 0.7–0.8 mm. AL = 1.3 mm. BL = 3.4–3.9 mm (n=10) (3), 4.4–4.7 mm (n=10) (Ƥ).

Host plants: swept from Cousinia refracta (Bornm.) Juz. , which is probably a host plant.
