Megaselia namakiae Khaghaninia & Disney View in CoL n. sp.

( Figs 243–254 View FIGURES 243–250 View FIGURES 251–254 )

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 (58, CUMZ—13-88). GoogleMaps

Description. Male. Whole fly as Fig. 243 View FIGURES 243–250 . Frons as Fig. 244 View FIGURES 243–250 , devoid of microtrichia ( Fig. 245 View FIGURES 243–250 ). Cheek with one bristle and jowl with two that are longer and more robust. Postpedicels, palps and proboscis as Fig. 246 View FIGURES 243–250 , the postpedicels lacking SPS vesicles, and the labella with very few short spinules below. Thorax with 3 notopleural bristles and no cleft in front of these, and mesopleuron with hairs and one differentiated moderate bristle ( Fig. 247 View FIGURES 243–250 ). Scutellum with an anterior pair of short hairs and a posterior pair of bristles. Abdominal tergites and venter, which has fine hairs on segments 3–6, as Fig. 248 View FIGURES 243–250 . Hypopygium as Figs 248–250 View FIGURES 243–250 , and lacking hypandrial lobes. Legs light brown to brownish yellow. Fore tarsus with posterodorsal hair palisade on segments 1–4 and 5 slightly longer than 4 ( Fig. 251 View FIGURES 251–254 ). Dorsal hair palisade of mid tibia extends about 0.61 times its length. Hairs below basal half of hind femur about as long as those of anteroventral row of outer half ( Fig. 252 View FIGURES 251–254 ). Hind tibia with a dozen finely differentiated posterodorsal hairs, without anterodorsals, and spinules of apical combs simple. Wings ( Figs 253 & 254 View FIGURES 251–254 ) 1.20 mm long. Costal index 0.45. Costal ratios 3.78: 1.48: 1. Costal cilia (of section 3) 0.06 mm long. No vein 3 hair. 2 axillary bristles, the outermost being 0.09 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 48 where the lack of hypandrial lobes excludes both species. Nine excluded or later described species run to the same couplet, but only 2 lack hypandrial lobes. One of these has 4 not 2 axillary bristles and its front basitarsus has rows of small spinules; the other has a much longer anal tube and its proctor bears a pair of long, bristle-like hairs that are clearly longer and more robust than those on the cerci. At couplet 48 when neither lead fits a note directs one to couplet 60, from where one proceeds to couplet 93 and then on to couplet 126, where both species have at least 3 axillary bristles and the dorsal hair palisades of mid tibia on all five segments. 14 excluded or subsequently described species also run to couplet 126. One or more of the following excludes all of these. Brown palps, hairs only on the mesopleuron, epandrium with fine hairs only, a much longer anal tube, with at least one hypandrial lobe, more than 2 axillary bristles, and or longer costal cilia. In Schmitz’s (1958 b) key to Abteilung II it runs to couplets 25 lead 1 M. pectoralla Schmitz, but it has hypandrial lobes. In Borgmeier’s (1964 b) key to Nearctic Group II it runs to couplets 17 and 18. The hypopygia of these species were subsequently figured by Robinson (1981). All but one have at least one hypandrial lobe. The exception has small hairs and 4 bristles on the epandrium.
