Revision of the willow catkin flies, genus Egle Robineau-Desvoidy (Diptera: Anthomyiidae), in Europe and neighbouring areas Author Michelsen, Verner text Zootaxa 2009 2009-03-16 2043 1 1 76 https://biotaxa.org/Zootaxa/article/view/zootaxa.2043.1.1 journal article 10.11646/zootaxa.2043.1.1 1175­5334 5311138 15. Egle setiapicoides sp. nov. Figs. 126–131 , 189, 190 . Etymology. The specific epithet ‘setiapicoides’ is derived from setiapicis, existing epithet for a closely related, Nearctic species, and ‘-oides’, a Greek adjectival suffix meaning resembling. Description. Extremely small, wing length 2.1–2.6mm. Male. Prementum polished black, without any dusting. Subgena (narrow, bare sclerite between gena and subcranial cavity) also polished black. Parafacial in middle narrower than postpedicel. Lower facial margin weakly projected, reaching no further than level of fronto-parafacial angle. Genal setae few, standing in a single row. Prealar seta about half as long as posterior notopleural seta. Proepisternals 1; proepimerals 1–2. Lower calypter very reduced, forming a narrow fold with barely convex hind margin. Scutellum sometimes without usual minute setulae beneath tip. Submedian tibial setae: fore tibia with 0 pd- and 0 p-setae; mid tibia with 0 ad-, 1 pd- and 0 p-setae; hind tibia with 2–3 av-setae, without distinct p–pv-setae. Hind femur with some short pv-setae on basal half. Tergite VI small, firmly attached to fore margin of syntergosternite VII+VIII. Sternite V ( Figs. 126, 127 ) characteristic, with 2 long, close-set setae at apex of posterior lobes; at transition between basal plate and posterior lobes with 2–3 lateral setae, otherwise bare except for some fine setulae in middle of hind marginal incision. Terminalia ( Figs. 128–131 ): shape of surstyli and cerci diagnostic. Female. Prementum and subgena polished black. Lower facial margin weakly projected, in line with fronto-parafacial angle. Prealar seta about half as long as posterior notopleural seta. Proepisternals 1(–2); proepimerals 1–2. Lower calypter very reduced, forming a narrow fold with barely convex hind margin. Scutellum sometimes without usual minute setulae beneath tip. Submedian tibial setae: fore tibia with 0 pd- and 0 p-setae; mid tibia with 1 short ad- and 1 pd-setae; hind tibia with 1–2 av-setae. Hind femur without pvsetae on basal half. Oviscapt ( Figs. 189, 190 ): Sternites VI and VII widely membranised on middle part; sternite VIII absent; small epiproct bare; hypoproct V-shaped, with two pairs of setulae on apical part; cerci small and slender. Spermathecae two normal-sized and cross-wrinkled, one only retained as rudimentary duct. FIGURES 126–131. Egle setiapicoides , male terminalia [paratype: Uzbekistan]. 126, 127. Sternite V, ventral and lateral views. 128, 129. Hypopygium, caudal and lateral views. 130. Pre- and postgonites, lateral view. 131. Phallus, lateral view. Same scale. Material examined. Type material [ ZMUC ]: UZBEKISTAN : Samarqand , along river Zeravshan , 1 male , 2 females 22.v.1989 , ( M. Barták ); Zeravshan reserve , deciduous wood, 5 males (including holotype ), 2 females 21–22.v.1989 ( M. Barták ) . Distribution. Known only from the type series from near Samarqand, Uzbekistan . Relationships. Obviously very closely related to E. setiapicis ( Huckett, 1965 ) , a species known only from the male holotype from Yukon Territory ( Canada ). On the basis of my own unpublished drawings of the holotype terminalia and Griffiths’ (2003) illustrated redescription of the holotype I find that E. setiapicis differs from E. setiapicoides as follows: Sternite V with posterior lobes broader, notably raised and angular at inner margins, apically with 3 long, close-set setae; surstyli more slender, in both lateral and rear views without a distinct medial notch distal to middle; apical extension of cerci apparently more slender.
