Diagnosis: Coloration of body, legs and hairs of male as in female below. Genitalia with surstylus broadened distally ( Fig. 31 View FIGURES 24 – 33 ); Phallus ( Fig. 5 View FIGURES 1 – 6 ) with phs strongly curved; tdp short and broad, Lmtdp:Ltdp~4.5; the two php are narrow and distinctly shorter than mtdp; the upper ejaculatory duct is placed distally on mtdp, whereas the lower two are slightly before the middle of mtdp; ejaculatory apodeme spade-shaped ( Fig. 16 View FIGURES 12 – 23 ). Female with frontal facets greatly enlarged (J92 Fig. 1 View FIGURES 1 – 6 B); frons narrow, at narrowest point 1.5 times diameter of largest frontal facet; flagellum mid to dark brown; femur dark brown, but base and apex may be broadly yellow; tibia vary from dark brown with yellow base and apex to yellow with brown middle, tarsi yellowish; pulvilli of front and mid legs twice the length of hind legs and longer than distitarsus; hairs on femora, thorax and abdomen yellow to mid brown; hind femur with apical hairs of pdsr extending further than apex; abdomen rather narow; abdominal tergites mid to dark brown; ovipositor as in Figs 43 & 45 View FIGURES 34 – 48 . See Table 1 for coxI and ITS2 barcode sequence accession numbers.

Annotations: Superficially, male C. juliae can strongly resemble C. fimbriatus and C. pughi . However, the structure of male genitalia differs considerably. Also, males lack any distinct black peg-like setae on sternite 5. Compared to the closely allied C. latifrons , the distance between the two lower and the single upper ejaculatory duct is slightly greater. An additional male from China (CK353) was sequenced on ITS2. Its genotype differs from European specimens by one insertion and the deletion of a dinucleotide microsatellite repeat only, providing evidence for the presence of the taxon in the eastern Palaearctic. Morphologically, females are closest to C. leticiae and care has to be taken when assessing the lateral shape of the ovipositor (compare Figs 45–46 View FIGURES 34 – 48 ). C. juliae has so far been reared from Empoasca vitis (Göthe) .
