Description. Head ( Fig. 27 View FIGURES 23 – 28 ): Structure: 1.16–1.32 times as high as long. Frons posteriorly 1.20–1.33 times as wide as long and at lunule level 1.42–1.56 times as wide as long, with pits. Eye 1.03–1.15 times as high as long. Gena 0.33–0.36 times as high as eye, canaliculate. Fronto-orbital plate at antenna insertion level 0.28–0.32 times as long as eye. Color and vestiture: Head mostly black. Frons, parafacial and gena often reddish-brown. Fine microtrichose white line present at orbit along eye. First flagellomere silvery microtrichose; arista bare, mostly brown, except sub-basal 0.33 whitish. Setae and setulae: Medial vertical seta as long as lateral vertical seta; ocellar seta 0.52–0.57 times as long as medial vertical seta; postocellar seta 0.40–0.45 times as long as medial vertical seta; orbital seta 0.45–0.57 times as long as medial vertical seta. Frons short setulose. Gena with 1 seta and several setulae. Postgena long setulose. Long black setulae on palpus; labellum with mixed black and white setulae.

Thorax: Black, densely shagreened. Setae and setulae: 2 supra-alar, 2 dorsocentral, 1 acrostichal, 4–6 anepisternal, and 4–6 (anterior and posterior) katepisternal setae present. Postpronotal lobe, scutum, scutellum, anepisternum and katepisternum setulose, setulae 0.4–0.5 times as long as major setae.

Legs: Foretarsus with 1–3 basal tarsomeres brown to orange; midtarsus and hindtarsus with 1–3 basal tarsomeres orange to yellow; remaining parts black. Hindfemur (Figs. 44,45) widened in males, 2.2–2.4 times as wide as midfemur.

Wing (as in Fig. 33 View FIGURES 29 – 38 ): Hyaline, no pattern present; pterostigma mat yellow. Venation: Veins yellow to orange. Crossvein R-M aligned slightly proximal to apex of vein R1. Ratios: Cell r4+5 0.26–0.34; vein Cu2 0.57–0.80. Calypteres white. Halter base and stem brownish, knob yellow to orange.

Abdomen: Tergites mostly smooth, except tergite 5 densely shagreened. Abdomen with long setulae.

Phallus with 1 caecum; caecum extending along apical half of phallus. Glans ( Fig. 84 View FIGURES 78 – 85 ) bifurcate, with small apical spines.

Female terminalia: Aculeus at widest point 8.0–8.2 times as long as wide and 1.5–1.6 times as wide as immediately anterior to cercal unit. Cercal unit ( Fig. 98 View FIGURES 93 – 99 ) triangular, apically pointed, with well pronounced lateral groove. Sensilla: BV apical to BD. Spermathecae globulose (as in Fig. 107 View FIGURES 100 – 109 ) with smooth surface.

Measurements (mm): Body length 3.4–4.5, wing length 2.9–3.7.

Type locality. "Wadi Wirak, northern Galala" (east of El Saff) ( Egypt).

Distribution. Egypt, Israel.

Adult activity in Israel: March to May.

Diagnosis. This species differs from its congeners in the sexually dimorphic hindfemur, which is strongly widened in males.

Comments. The above mentioned character is not reported in the original description despite the fact that the holotype is a male. However, the whereabouts of the holotype is unknown, and it has not been studied. Therefore the species recorded here might turn out to be different from Steyskal’s U. wadicola .
