description: Megaselia evogliensis n. sp.
(Figs 94–109)
Material examined. Holotype male, West Azerbaijan province, Khoy city, Evogli region, 38°42.436’N, 45°12.246’E, 968 m, Malaise trap, 26.ix.2013, S. Khaghaninia (48, CUMZ—13-97).
Description. Male. Whole fly as Fig. 94. Head as Fig. 95. Frons as Fig. 96, totally lacking fine microtrichia (Fig. 97). Cheek with 6 strong bristles and jowl with 3, one longer and 2 similar to those on cheek. Postpedicels, which lack SPS vesicles, and proboscis as Fig. 98. Proboscis from below as Fig. 99. Thorax brown, with 3 notopleural bristles and no cleft in front of these, and mesopleuron as Fig. 100. Scutellum with an anterior pair of small hairs and a posterior pair of bristles. Abdominal tergites brown, 2–6 with numerous hairs towards lateral margins but minute hairs along the median band; some longer hairs at rear of T5 and long bristles at rear of T6 (Fig. 101). Venter gray with relatively few small hairs on segments 3–6. Hypopygium as Figs 101–103. The hypandrium has a small bristle each side and unusually has a tapered process between them (Fig. 104). Legs with brown femora and tibiae. Fore tarsus with posterodorsal hair palisades on segments 1–4 and 5 a little longer than 4 (Fig. 105). The basitarsus has some rows of hairs reduced to much shorter and finer hairs (Fig. 106). Dorsal hair palisade of mid tibia extends about 0.84 times its length. Hairs below basal half of hind femur about as long as those of anteroventral row of outer half (Fig. 107). Hind tibia with 6 of the 8 differentiated posterodorsal hairs robust, without anterodorsals, and spinules of apical combs simple (Fig. 108). Wings (Fig. 109) 1.63 mm long. Costal index 0.41. Costal ratios 3.50: 1.29: 1. Costal cilia (of section 3) 0.032 mm long. Vein 3 hair 0.025 mm long. 2 unequal axillary bristles, the outermost being 0.05 mm long. Sc not reaching R1. Haltere knob brown.
Recognition. In the key to the Megaselia males of the British Isles (Disney 1989) it runs to couplet 47 where neither option fits due to their very different hypopygia. Of four omitted Palaearctic species, 3 have brown palps and M. tama (Schmitz) has a very different hypopygium. In the key of Schmitz (1958) to Abteilung III it runs to couplets 17 or 26. At 17 both options have very different hypopygia. At couplet 26 again the hypopygia for both options are clearly different. Some M. curvicapilla Schmitz may run to this couplet instead of 17, its darker venter with much more numerous and more robust hairs instantly distinguishes it. The later described M. haranti Delage & Lauraire (1970) will run to this couplet, its 5 axillary bristles and longer hairs below the hind femur rule it out. It fails to key out for the rest of the world.
Etymology. Named after the Evogli Region.
