Redescription. Head (Fig. 26): Structure: 1.01–1.10 times as high as long. Frons of same width posteriorly and at lunule level, 1.27–1.49 times as wide as long, striate, medially concave. Eye 1.00–1.07 times as high as long. Gena 0.35–0.45 times as high as eye, strigose posteriorly. Fronto-orbital plate at antenna insertion level 0.39–0.42 times as long as eye. Palpus conspicuously longer than subcranial cavity. Color and vestiture: Head mostly reddishbrown. Frons black posteriorly. Fine microtrichose white line with frontal triangular widening present at orbit along eye. Parafacial brown to black. Postgena, occiput and ocellar triangle black. Occiput black, slightly white microtrichose. First flagellomere black to orange, silvery-gray microtrichose; arista black, with short rays. Setae and setulae: Medial vertical seta as long as lateral vertical seta; ocellar seta 0.85–0.97 times as long as medial vertical seta; postocellar seta 0.55–0.60 times as long as medial vertical seta; orbital seta 0.75–0.81 times as long as medial vertical seta. Frons densely long setulose, setulae as long as orbital seta. Lunule setulose. Vibrissal angle setulose. Gena and postgena long setulose; 3–4 genal and postgenal setae. Palpus with long black setulae. Labellum with long mixed black and white setulae.
Thorax: Color and vestiture: Subshiny reddish-black, shagreened. Proepisternum ventrally, katepisternum medially, notopleuron posteriorly, katatergite and often anepisternum medially slightly white microtrichose. Setae and setulae: 1 supra-alar, 1 dorsocentral, 3–5 anepisternal and 1 katepisternal setae present. Postpronotal lobe, scutum, scutellum, anepisternum and katepisternum setulose; setulae 0.33–0.40 times as long as major setae.
Legs: Entirely blackish-brown; forecoxa slightly white microtrichose. Hindfemur not widened, as wide as midfemur in both sexes.
Wing (as in Fig. 35): Pattern: wing with basal-cubital cell and basal half of cubital cell brown, and with apical brown spot, extending from costa at apices of cells r1, r2+3 and mid-apex of r4+5; pterostigma mat brown, and part of cell r1 adjacent to pterostigma often infuscate; otherwise, wing hyaline to slightly infuscate. Venation: Veins mostly brown to black, except basal 0.2 of veins A1+Cu2 and Cu1 yellow. Crossvein R-M aligned with apex of vein R1. Ratios: Cell r4+5 0.35–0.39; vein Cu2 0.90–1.05. Calypteres white. Halter gray-brown.
Abdomen: Tergites slightly shagreened and setulose.
Male terminalia: Epandrium (Fig. 60) as high as wide; cerci triangular, deeply separate; lateral surstylus apically pointed. Phallus with 1 caecum; caecum extending along medial 0.33 of phallus. Glans (Fig. 83) elongate, with small apical hook and large apical elongation.
Female terminalia: Aculeus 7.0–8.8 times as long as wide at widest point. Cercal unit (Fig. 97) oval, pointed apically. Sensilla: BV apical to BD. Additional pair of lateral, short setulae present apical to BD, ventrally, and additional pair of short medial setulae present, aligned with SAVP. Spermathecae globulose (Fig. 108), with shagreened surface.
Measurements (mm): Body length 4–5, wing length 3.7–4.5.
Type locality. " Pers. Beludshistan von den Quellen des Flusses Ssarbas" (Sarbaz Province, SE Iran).
Distribution. Southwestern Asia.
Adult activity in Israel: end of March to beginning of August.
Diagnosis. This species differs from its congeners in the following combination of characters: palpus longer than subcranian cavity, frons medially concave and dorsocentral setae absent.
Comments. This species exhibits conspicuous variation in several characters and body parts: some specimens lack the apical wing-spot; halter coloration varies from black to yellow; length and density of the setulae on the frons and thorax are inconstant (Kameneva, personal communication). However, these variations were not exhibited in the specimens we studied.
