Description. Head (Fig. 24): Structure: 1.14–1.29 times as high as long. Frons of same width posteriorly and at lunule level, 1.38–1.54 times as wide as long, with shallow pits, slightly shagreened. Eye 1.06–1.12 times as high as long. Gena 0.28–0.36 times as high as eye, strigose. Fronto-orbital plate at antenna insertion level 0.16– 0.21 times as long as eye. Color and vestiture: Head mostly reddish-black. Fine microtrichose white line present at orbit along eye. First flagellomere silvery microtrichose. Arista with short rays. Setae and setulae: Medial vertical seta as long as lateral vertical seta; ocellar seta 0.51–0.58 times as long as medial vertical seta; postocellar seta 0.33–0.35 times as long as medial vertical seta; orbital seta 0.58–0.68 times as long as medial vertical seta. Frons, gena and postgena densely long setulose; vibrissal angle setulose. 1 genal seta. Palpus with long black setulae; labellum with mixed black and white setulae.
Thorax: Color and vestiture: Black, densely shagreened. Notopleuron ventrally and katatergite white microtrichose. Setae and setulae: 2 supra-alar, 1 dorsocentral, 1 acrostichal, 3–6 anepisternal and one katepisternal setae present. Postpronotal lobe, scutum, scutellum, anepisternum and katepisternum relatively long setulose; setulae 0.40–0.45 times as long as major setae.
Legs: Mostly black except mid and hind tarsi with 2 basal tarsomeres yellow. Hindfemur not widened, as wide as midfemur in both sexes.
Wing (Fig. 36): Pattern: wing hyaline basal to crossvein BM-Cu, infuscate apical to crossvein BM-Cu; pterostigma mat brown. Venation: Veins yellow in hyaline part, brown to black in infuscate part. Crossvein R-M aligned with apex of vein R1. Ratios: Cell r4+5 0.37–0.47; vein Cu2 1.37–1.46. Calypteres white. Halter base and stem brown, knob orange to yellow.
Abdomen: Tergites slightly shagreened and setulose.
Male terminalia: Epandrium (Fig. 58) 1.13–1.14 times as high as wide; cerci triangular, slightly separate; lateral surstylus apically pointed; medial surstylus with 15–18 prensisetae. Phallus with one caecum extending along apical half of phallus. Glans (Fig. 81) somewhat triangular-shaped, with apical hook and small beak-like structure.
Female terminalia: Aculeus at widest point 8.7–9.6 times as long as wide. Cercal unit (Fig. 95) oval, apically rounded, with well pronounced lateral groove. Sensilla: BV apical to BD. Additional pair of lateral, short setulae present apical to BV. AD seta situated somewhat basally, nearly aligned with AV. Spermathecae (as in Fig. 107) globulose with smooth surface.
Measurement (mm): Body length 4.7–5.6, wing length 3.3–4.0.
Type locality. "Schlesien und das Grossherzogthum Posen" (Poland).
Distribution. Central and Southern Europe, Israel.
Adult activity in Israel: Middle of May to beginning of July.
Diagnosis. This species differs from its congeners in the following combination of characters: microtrichose line at orbit and infuscate wing.
Comment. According to preliminary molecular work, U. nigripennis may be a complex of species (Smit, personal communication).
