Redescription. Head (Fig. 9, 15): Structure: 1.14–1.23 times as high as long. Frons posteriorly as wide as long and at lunule level 1.25–1.29 times as wide as long, smooth, medially slightly concave. Eye 1.0–1.2 times as high as long. Gena 0.41–0.47 times as high as eye, strongly corrugated posteriorly. Fronto-orbital plate at antenna insertion level 0.21–0.27 times as long as eye. Color and vestiture: occiput mainly black, except median occipital sclerite orange laterally and black medially (black area continuous with ocellar triangle), silvery microtrichose. Vertex orange medially, black laterally, silvery microtrichose. Ocellar triangle black, silvery microtrichose. Frons brown, posteriorly white microtrichose. Face, orbit, parafacial and gena in male shiny brown to black, in female usually shiny yellow to orange, except ca. 10% of females similar in this regard to males. Postgena black, silvery microtrichose. First flagellomere brown, silvery microtrichose. Arista brown to golden, with microscopic rays. Palpus brownish black, silvery microtrichose. Setae and setulae: all setae and setulae (except on labellum) black. Medial vertical seta 1.0–1.1 times as long as lateral vertical seta; ocellar seta 0.43–0.57 times as long as medial vertical seta; postocellar seta 0.30–0.42 times as long as medial vertical seta; 1–2 orbital setae present, each 0.43– 0.60 times as long as medial vertical seta. Frons setulose, setulae 0.9 times as long as ocellar seta. Gena with several short setulae anteriorly and 2–4 long setae posteroventrally; postgena with long setulae. Palpus with long black setulae; labellum with long, mixed black and white setulae.
Thorax: Color and vestiture: black. Scutum, katatergite and scutellum silvery-white microtrichose; remaining parts subshiny, slightly shagreened. Setae and setulae: All setae and setulae black. 1 acrostichal, 4–6 anepisternal, 1 short supra-alar, 1–4 katepisternal and 2 scutellar setae present. Regular row of dorsocentral setulae and slightly irregular row of acrostichal setulae present. Postpronotal lobe, scutum, anepisternum and katepisternum setulose; setulae about 0.33 times as long as major setae. Scutellum bare.
Legs: Mostly black, except mid and hind 1–2 basal tarsomeres yellow.
Wing (Fig. 30): Brown to black apical spot extending through apices of cells r2+3 and r4+5, remaining part of wing hyaline; pterostigma mat brown to black. Venation: Veins yellow. Crossvein R-M aligned with apex of vein R1. Ratios: Cell r4+5 0.38–0.44; vein Cu2 1.19–1.30. Calypteres white. Halter base and stem brown, knob orange to white.
Abdomen: Tergites black, tergites 3 and 4 subshiny, tergite 5 shagreened.
Male terminalia: Epandrium (Fig. 48) as high as wide; cerci triangular, separate; lateral surstylus medially bent and apically pointed, prensiseta absent. Phallus (Fig. 63) with long caecum; caecum extending along apical half of phallus and with basal microsetulose bulb. Glans (Fig. 71) elongate, with sclerotized "body" and membranous apex.
Female terminalia: Cercal unit (as in Fig. 91) triangular, apically pointed, with well pronounced lateral groove; aculeus 10.7–20.5 times as long as wide. Sensilla: BV apical to BD. Spermathecae globulose, slightly conical (Fig. 102) with smooth surface.
Measurements (mm): Body length 2.7–3.8, wing length 2.4–3.5.
Type localities: "Zaidam im nordöstl. Tibet; Kurlyk am Baingol; Itsche-See und Orogyn" (North China).
Distribution. North China (Tibet); Israel.
Adult activity in Israel: March.
Diagnosis. This species differs from its congeners in the following combination of charcters: sexually dimorphic face coloration, wing with blackish pterostigma and apical spot, phallus with long caecum and microsetulose bulb.
Comments. This species has a rather peculiar distribution: It is known from China (Type locality) and from a single small area ('En 'Avedat and 'En Mor are only about 2.5 Km apart) in Israel.
