Redescription. MALE ( Figs 9 View FIGURES 7 – 12 , 27 View FIGURES 25 – 30 ). Body length: 11.1–12.1 mm; wing length: 8.5–9.3 mm. Head ( Fig. 44 View FIGURES 37 – 48 ). Face slightly protruding antero-ventrally with weakly demarcated tubercle and slightly concave below antennae. Head 2.2–2.4 times wider than face just below the antennae; length of eye contiguity 0.59–0.63 times as long as length of frons; angle of eyes at eye contiguity 120–145o. Gena, mouth edge, hypostomal bridge and a fascia around frontal prominence black. Vertical triangle and ocellar triangle black, sometimes brown to yellow; dorsal surface of head capsule yellow. Frontal prominence 3.8–5.0 times longer than wide; relative length of pedicel is as 1.0–1.2: 1: 0.82–0.87. Antennae and frontal prominence brown-yellow coloured; arista white pilose. Thorax. Scutum black with yellow maculae on postpronotum and notopleuron; a yellow vitta from postalar callus to suture at both sides, sometimes missing. Pleuron black with two yellow maculae, one each on posterior 1/2–3/5 of posterior anepisternum and on dorsal 1/4–1/3 of katepisternum, sometimes an additional small yellow macula on anteroventral part of anterior anepimeron. Metasternum with short pile and a low, rounded elevation medially on anteroventral part. Scutellum entirely yellow, sometimes posterior margin narrowly black. Legs. Coxae black; trochanter yellow; apico-medial 1/4–2/3 of pro- and mesofemur black; apical 1/4–1/3 of metafemur black; apico-medial 1/2– 1/3 of tibiae black; pro- and mesotarsus brown-yellow to black; metatarsus black. Clear patch of black setulae present on antero-basal part of pro- and mesofemur and on medial part of metatrochanter. Mesotrochanter straight dorsally; mesofemur with rather long and rugged flattened area antero-basally; metatrochanter with weak sulcus and narrow rim laterally ( Fig. 70 View FIGURES 64 – 70 ); metatibia without triangular appendix on apico-ventral part; metafemur elongate and slightly curved ( Fig. 92 View FIGURES 90 – 93 ). Wing. Hyaline except for anterior 1/2 and along spurious vein and along cross-vein bm-cu; sometimes even cells c and cs hyaline. Loop in vein R4+5 deep with short appendix into cell r4+5; hyaline. Cross-vein r-m slightly curved. Membrane covered in microtrichia, except on antero-basal part of cell dm; anterior part of cell bm narrowly bare; cell br posterior of vena spuria bare. Alula relatively broad, 2.8–3.3 times longer than wide. Abdomen. Black and yellow coloured. Length of tergite I: II: III: IV is as 1: 1.7–1.9: 1.7–1.9: 2.1–2.2. Width of yellow fascia medially: length of tergite of respectively tergite II, III and IV as 1: 3.1–3.3, 1: 3.7–4.2 and 1: 2.5–2.6. Tergite II wider than long, anterior part most narrow; length of tergite II: width of tergite II at respectively anterior: posterior as 1: 1.1–1.3: 1.3–1.5. Tergite I with large triangular yellow maculae on anterolateral corner, narrowly separated medially; fascia on tergite II concave medially and only little narrowed at lateral margin; fascia on tergite III straight and only slightly narrower at lateral margin; fascia on tergite IV straight, strongly narrowed towards lateral margin and reaching the lateral margin. Tergite IV with narrow margin. Tergites pock pitted with short white pile; sternites with longer white pile; pile about as long as width of metafemur. Tergite I with very low medial elevation; tergites III and IV without longitudinal elevation; with vague grey-white pollinosity medio-laterally. Sternites I–III with posterior yellow fascia. Genitalia. Epandrium with narrow ventral rim ( Figs 102, 104 View FIGURES 102 – 105 ); in dorsal view, cerci rounded triangular shaped, with apico-medial sharp pointed projection, apex rounded ( Fig. 104 View FIGURES 102 – 105 ), with pile about 1/4 as long as width of cerci; surstylus bi-lobed, dorsal lobe elongate, medially narrowed with wide oval apex, ventral lobe very narrowly circular with membranous basal part ( Fig. 102 View FIGURES 102 – 105 ); surstylar apodeme semi-circular shaped ( Fig 105 View FIGURES 102 – 105 ); hypandrium ( Figs 102, 103 View FIGURES 102 – 105 ) with broad base and narrower apex, in ventral view medio-laterally broadly shouldered; with long and elongated lingula with medio-ventrally a hardly sclerotized irregular shaped flange, without medio-dorsal projection, apico-laterally with two long broadly threadlike appendages; superior lobe large semi-circular shaped, articulating with hypandrium and with dorsal ctenidion consisting of about 10–15 short to long spines (these spines are shorter and more scattered along apical and medial part); aedeagus with baso-ventral elongated and pointed projection, medial projection long threadlike, dorsal projection broadly elongate with weak sclerotized apico-ventral flange.
FEMALE ( Figs 10 View FIGURES 7 – 12 , 28 View FIGURES 25 – 30 ). Body length: 10.1–12.9 mm; wing length: 7.9–9.5 mm. Similar to male, except for normal sexual dimorphism and the following characters. Head ( Fig. 45 View FIGURES 37 – 48 ). Head 2.0–2.2 times wider than face just below the antennae. Face with narrow medial black vitta. Frontal prominence 4.2–5.3 times longer than wide; relative length of pedicel is as 1.0–1.1: 1: 0.81–0.95. Vertex black. Wing. Alula relatively broad, 2.7–2.9 times longer than wide. Abdomen. Length of tergite I: II: III: IV: V is as 1: 2.0–2.2: 2.3–2.7: 1.9–2.1: 0.83–0.98. Width of yellow fascia medially: length of tergite of respectively tergite II, III and IV as 1: 2.6–3.0, 1: 3.6–3.8 and 1: 1.9– 2.1. Tergite II wider than long, anterior part most narrow; length of tergite II: width of tergite II at respectively anterior: posterior as 1: 0.92–1.0: 1.3–1.4.
Material examined. The types of C. sartorum were not studied. The description, however, is clear enough to assign the specimens studied here to this species. 33 Ƌ, 43 ♀ ( CDFA, NHM, ISEA, MNHN, NBC, ZIN).
Distribution ( Fig. 167 View FIGURES 166 – 168 ). Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, Uzbekistan.
Biology. Adults have been found visiting flowers of Berberis sp. Adults fly from late April to late July.
