( Figs 75–84 ) Description . (Male). In the key to the males of the species of Megaselia recorded from the British Isles ( Disney 1989 ) it runs to couplets 283 and 285, but the hypopygia differ, notably the vestigial hypandrial lobes but long hypandrial bristles immediately rule out these species. It differs from subsequently added species running to these couplets. In Borgmeier’s (1966) key to Nearctic species of Group VII it runs to couplet 36 lead 1 M. crinifrons Borgmeier, but it has 5 axillary bristles and wings exceeding 2 mm in length. It fails to run down in the rest of the world fauna. Male . Frons as Fig. 75 , with dense but very fine microtrichia. Cheek with 5 bristles and jowl with 2 that are longer and more robust. Postpedicels with SPS vesicles and as Fig. 76 . Palps Fig. 77 . Proboscis with labella lacking short spinules below and labrum pale. Thorax dusky orange, with 2 notopleural bristles and no cleft in front of these, and mesopleuron bare ( Fig. 78 ). Scutellum with an anterior pair of small hairs and a posterior pair of bristles. Abdominal tergites and venter as Fig. 79 . Hypopygium as Figs 80 & 81 , with vestigial hypandial lobes but long bristles. Legs pale. Fore tarsus ( Fig. 82 ) with posterodorsal hair palisade on segments 1–4 and 5 a little longer than 4. Dorsal hair palisade of mid tibia extends about 0.69 times its length. Hairs below basal half of hind femur longer than those of anteroventral row of outer half ( Fig. 83 ). Hind tibia with 17–18 moderately differentiated posterodorsal hairs, without anterodorsals, and spinules of apical combs simple. Wings ( Fig. 84 ) 1.53 mm long. Costal index 0.56. Costal ratios 2.5: 1.5: 1. Costal cilia 0.08 mm long. Vein 3 hair 0.04–0.05 mm long. With 2 unequal axillary bristles. Sc absent. Haltere knob brown. Figures 75–84. Megaselia setaeneclobi Disney , sp. nov. male. 75 – frons; 76 – postpedicel; 77 – palp; 78 – side of thorax; 79 – side of abdomen; 80 – left face of hypopygium; 81 – right face of hypopygium; 82 – front tarsus, 83 – hind femur; 84 – wing. Type material . Holotype male, Poland , Wigry National Park , in emergence trap in plot 5 with Impatients parviflora DC, IX. 2017 , E. Durska leg. ( MIZ PAS , – 28-61). Etymology . Named after having long hypandrial bristles (setae) but not ( nec ) with hypandrial lobes ( lobi ).
