(Figs 219–242)
Material examined. Holotype male and female, West Azerbaijan province, Miandoab city, Nasirkandy region, 36°56.846’N, 46°10.015’E, 1306 m, grassland, 12.VI.2016, S. Khaghaninia (45, CUMZ—13-99). Paratypes: 4 males and 1 female, locality data as the holotype (1♂ UCZM, 1♀, 3♂ ICHMM).
Description. Male. Whole fly as Fig. 219. Frons as Fig. 220, without fine microtrichia (Fig. 221). Cheek with 3 bristles and jowl with 2 that are longer and more robust. Postpedicels, which lack SPS vesicles, and proboscis as Fig. 222. Palps and proboscis as Fig. 223. Labella with many very fine and short spinules below (Fig. 224). Thorax and abdomen as Fig. 225. Thorax as female (Fig. 234), with 2 notopleural bristles and no cleft in front of these. Mesopleuron bare. Scutellum with an anterior pair of small hairs and a posterior pair of bristles (Fig. 226). Venter pale gray with a few small hairs on segments 4–6. Hypopygium as Figs 227 & 228, the left lobe of hypandrium being large but the right lobe being vestigial. Legs yellow apart from brown tips to hind femora brown. Fore tarsus with posterodorsal hair palisade on segments 1–4 and 5 longer than 4 (Fig. 229). Dorsal hair palisade of mid tibia extends about 0.76 times its length. Hairs below basal half of hind femur longer than those of anteroventral row of outer half (Fig. 230). Hind tibia with a dozen moderately robust differentiated posterodorsal hairs, without anterodorsals, and spinules of apical combs simple. Wings (Fig. 231) 1.38–1.83 mm long. Costal index 0.32–0.33. Costal ratios 5.46– 5.76: 1.58–1.72: 1. Costal cilia (of section 3) 0.10 mm long. Vein 3 hair 0.05–0.06 mm long. 3 axillary bristles, the outermost being 0.14 mm long. Sc not reaching R1. Haltere knob pale yellow (Fig. 225).
Female. Whole fly as Fig. 232. Frons similar to male. Antennae, palps and proboscis as Fig. 233, the labella lacking the small spinules of the male. Side of thorax (Fig. 234) with scutellum as male (Fig. 226). Abdomen as Fig. 235, the venter being gray with dark bands adjacent to tergites and with small hairs on segments 3–6. Tergite 7 as Fig. 236. Sternite 7 as Fig. 237. Rear end of sternum 8 with a pair of finger like lobes (Fig. 238). Dufour’s crop mechanism as Fig. 239. Furca not evident. Legs similar to male (Figs 240 & 241). Wing (Fig. 242) length 2.29 mm long and costal index 0.32. Costal cilia 0.10 mm long, vein 3 hair 0.05–0.06 mm long, 4 axillary bristles, the outermost being 0.12 mm long. Otherwise it and haltere as male.
Recognition. In the key to the Megaselia males of the British Isles (Disney 1989) it runs to triplet 218, but its yellowish thorax, shorter costal index and hypopygium excludes all 3 species. A further 9 excluded or subsequently described species run to the same triplet, but only M. jorgensis Disney has a yellowish thorax, but it has an unforked vein 3 and a different hypopygium. Our species does not key out in the rest of the world’s fauna.
Etymology. Named after Miandoab city.
