Megaselia khoyensis n. sp.

(Figs 177–189)

Material examined. Holotype male, West Azerbaijan province, Khoy city, Evogli region, 38°42.436’N, 45°12.246’ E, 968 m, Malaise trap, 26.IV.2013, S. Khaghaninia (25, CUMZ—13-85) . Paratypes: 23 males, locality data as the holotype (1 UCZM, 22 ICHMM) .

Description. Male. Whole fly as Fig. 177. Frons as Fig. 178, with very fine microtrichia restricted to edges (Fig. 179). Cheek with 5 bristles and jowl with 2 that are much longer and more robust. Postpedicels, without SPS vesicles, palps and proboscis as Fig. 180. Thorax brown, with 3 notopleural bristles and no cleft in front of these, and mesopleuron as Fig. 181. Scutellum with an anterior pair of hairs and a posterior pair of long bristles (Fig. 182). Abdominal tergites brown and venter grey and with hairs on segments 3–6 (Fig. 183). Hypopygium as Figs 183–186), being especially notable for the exceptionally long left hypandrium (Fig. 185). Legs light brown to yellowish brown. Fore tarsus with posterodorsal hair palisade on segments 1–4 and (Fig. 187). Dorsal hair palisade of mid tibia extends about half its length. Hairs below basal half of hind femur clearly longer than those of anteroventral row of outer half (Fig. 188). Hind tibia with 16–20 moderately differentiated posterodorsal hairs, without anterodorsals, and spinules of apical combs simple. Wings (Fig. 189) 1.58–1.63 mm long. Costal index 0.40–0.42. Costal ratios 3.2–3.5: 1.55–1.58: 1. Costal cilia (of section 3) 0.1–0.11 mm long. No vein 3 hair. Two unequal axillary bristles (Fig. 182), the outermost being 0.10–0.11 mm long. Sc not reaching R1. Haltere brown.

Recognition. In the key to the Megaselia males of the British Isles (Disney 1989) it runs to couplet 58 lead 2 to M. rudis (Wood) along with 6 subsequently added or new species. However, the hypopygium, especially the exceptionally long left hypandrial lobe, immediately distinguishes our species. In Schmitz’s (1958) key to Abteilung III it runs to couplet 24 lead 2 or couplet 27, but again the distinctive hypopygium excludes our species.

Etymology. Named after the type locality.
