Megaselia khaghaniniai Namaki & Disney n. sp.

( Figs 165–176 )

Material examined. Holotype male, West Azerbaijan province, Khoy city, Pere region, 38°41.719’ N, 44°54.041’ E, 1405 m, montane grassland, 22.V.2012, S. Khaghaninia (57, CUMZ—13-99).

Description. Male. Whole fly as Fig. 165 . Frons as Fig. 166 , with dense but very fine microtrichia ( Fig. 167 ) and notable for the lower supra-antennal bristles being as long as the upper pair, which are further then the pre-ocellar bristles, and the anterolaterals being well above the antials which are situated close to the eye margins. Cheek with a single bristle and jowl likewise but it is longer and more robust. Postpedicels brown, without SPS vesicles, the yellow palps and proboscis as Fig. 168 , the labella with only a few short hairs/spinules below. Thorax brown. With 3 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. Abdominal tergites brown with small hairs hairs, but 1–2 longer ones at sides of T2 and at rear of T6; and venter paler brown with hairs on segments 3–6. Hypopygium as Figs 169–173 , the hairs on epandrium being smaller than those at rear of tergite 6, on cerci and proctor apart from one posterolaterally that is more robust than rest and longer than the hairs of procter. The hypandrial lobe of the right side is vestigial. Legs yellow apart from dark tip to hind femur. Fore tarsus slender with postero-dorsal hair palisades on segments 1–5 ( Fig. 174 ). Dorsal hair palisade of mid tibia extends about 0.58 times its length. Hairs below basal half of hind femur longer than those of the anteroventral row ( Fig. 175 ). Hind tibia with 10 differentiated posterodorsal hairs with all but the basal 2 robust ( Fig. 175 ), without anterodorsals, and spinules of apical combs simple. Wings ( Fig. 176 ) 2.32 mm long. Costal index 0.49. Costal ratios 3.34: 2.31: 1. Costal cilia (of section 3) 0.09 mm long. No vein 3 hair. 2 unequal axillary bristles, the outermost being 0.14 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 203, where each lead only applies in part. In Borgmeier’s (1966) key to Nearctic Group VII it runs to couplet 37 lead 1 M. fungicola (Coquillett) but its lower supra-antennal bristles are much shorter and finer than the upper pair and its wing is less than 1.5 mm long.

Etymology. Named after professor Samad Khaghaninia, who collected the specimens described in this paper.
