Description. Male: Head. Ground-colour black. Frons broad, just above lunule 0.34 of head-width at this point. Eye bare. Fronto-orbital plate light grey pruinose; parafacial, face, gena and lower occiput silvery pruinose, rest of occiput light grey. Fronto-orbital plate narrow, at middle just under half width of frontal vitta at this point. Frontal triangle light grey, long and thin, reaching almost to lunule. Inner vertical very long, twice as long as adjacent orbital seta, outer vertical not distinct from adjacent post-ocular setulae, the latter in one row and with a partial second row below. Ocellar setae short, subequal to orbital seta. Three pairs of inclinate frontal setae, the middle one short; 1 pair of reclinate orbitals. Antenna black, apical half of pedicel sometimes pale; postpedicel in lateral view 3 times as long as wide, falling short of mouth-margin by half of its length, the anterior tip angular but not produced into a distinct point. Arista unusually long, just over twice as long as the length of postpedicel; virtually bare, the longest individual hairs shorter than its basal diameter. Parafacial narrow throughout. Vibrissal angle behind level of profrons; vibrissae strong, crossed. Gena moderate, the depth below lowest eye-margin 0.3 times length of postpedicel. Mentum of proboscis brown, glossy. Palpus dark brown. Thorax. Ground-colour black, entirely light grey dusted. Scutum with a pair of weak, narrow vittae running along the dorsocentral lines, from presutural dorsocentral to second postsutural dorsocentral. Without spinulose setulae at neck or on postpronotal lobes. Acrostichal setulae weak, in 1–2 irregular rows. Dorsocentrals 1+3. Inner postpronotal seta fine and half as long as outer seta. Two postsutural intraalars. Two proepisternal setae. Anterior and lower katepisternal setae subequal. Scutellum with the usual apical and subbasal lateral setae; disc with only 2–5 setulae. Legs. Coxae dark, light grey dusted; trochanters yellow; fore femur black, yellow at base and at tip; mid and hind femora mainly yellow, black on apical half (mid femur) or third (hind femur), broadly yellow at tips. Tibiae yellow. Tarsomeres black. Tarsomeres not expanded. Fore femur with posteroventral row complete, long; setae of the posterodorsal row short, especially in basal third. Fore tibia with a fine submedian posterior seta. Mid femur with short setae in basal half of anteroventral surface, less than femoral depth; posteroventral surface with 3–5 setae in basal half, slightly longer than femoral depth, with setulae in apical half; anterior surface with a few setae in basal half; 1 posterior preapical. Mid tibia with 1 very short anterodorsal and 1 submedian posterior seta. Hind femur on anteroventral surface with 3 short setae in basal third, 1 longer seta at middle, and 1 seta just before apex; posteroventral surface with 2–3 long setae in basal half and 1 short seta in apical half; anterodorsal row complete; 1 posterodorsal preapical setae. Hind tibia with 1 anterodorsal, 1 anteroventral; with a short posterodorsal, dorsal and anterodorsal preapical setae, only the dorsal strong and longer than tibial depth; 1 strong anteroventral apical seta. Wing. Weakly clear, veins yellow. Tegula and basicosta yellow. Veins bare, except for costa. Costal spine inconspicuous. Cross-vein r-m below the point where R 1 enters costa; dm-cu almost straight. Ratio of section of vein M between r-m and dm-cu, to cross-vein dm-cu, to apical section of vein CuA 1, is 1.8: 1.0: 1.8. Vein A 1 +CuA 2 very short, not reaching halfway from its base to wing-margin. Calypters white, margins creamy; lower calypter long, projecting beyond upper one by almost length of upper one. Haltere yellowish. Abdomen. Ground-colour black, entirely light grey dusted. Syntergite 1+2 without dark markings; tergites 3, 4, 5 each with a pair of dark lozenge-shaped spots, often rather indistinct, those on tergites 3 and 4 occupying much of tergal length, those on tergite 5 smaller and less distinct; the dusted area separating the spots as wide as the width of the spots themselves. Visible post-abdominal tergites grey dusted. Sternites grey dusted, sternite 5 with some shine at apex of each lobe. Setae indistinct and reduced, tergite 5 and sometimes 4 each with 1–3 discal setae, one of which is placed on or close to the dark spot. Sternite 1 bare. Terminalia ( Figs 14–19 View FIGURES 12–19 ). Sternite 5 almost V-shaped ( Figs 14, 17 View FIGURES 12–19 ). Cercal plate elongated, tapered apically ( Figs 15, 18 View FIGURES 12–19 ). Surstylus visibly shorter than cercal plate, narrowed distally, slightly concave posteriorly. Distiphallus tubular ( Figs 16, 19 View FIGURES 12–19 ). Measurements. Length of body, 3.5 mm. Length of wing, 3.0 mm.

Female: Very similar to the male and only differing as follows: Head. Antenna wholly black. Post-ocular setulae in a single row. Thorax. The pair of dark vittae on the scutum more distinctly marked, broader, and running from anterior presutural dorsocentral to 3rd postsutural dorsocentral. Legs. All femora black, yellow only at tips. Mid femur without anteroventral setae; with 2 posteroventrals in basal third. Mid tibia with the anterodorsal seta long and strong, twice as long as the posterodorsal. Hind tibia with the posterodorsal preapical vestigial. Abdomen. Tergite 3 with the dark spots almost coalescing medially. Tergite 5 without dark spots but with brown bristle-dots.

Measurements. Length of body, 3.0 mm. Length of wing, 3.0 mm.

Etymology. The specific name “ persica ” is the Latin equivalent of “Persian” that means native Iranian.

Remarks. In Hennig’s (1961a, b) key to Palaearctic Coenosia males, C. persica will key out to couplet 123 because mid femur is yellow on basal half whilst hind femur is yellow on basal two-thirds. Thereafter it will run to couplet 130 and to C. femoralis ( Robineau-Desvoidy, 1830) . C. femoralis is clearly distinct as it has hind tibia mostly brownish-black and mid femur with 1 anterior and 2 posterior preapical setae (no anterior and 1 posterior preapical seta in C. persica ).
