DIAGNOSIS: Recognized by the four brown rings on the antennal segment II, greenish mottling on forewings, greenish membrane cells, comparatively bright brown spot on the membrane, and structure of the male genitalia. Close to C. apanaskevichi and C. gracilis in external characters. Differs from C. apanaskevichi in the presence of long erect setae on the head and pronotum, spinelike sclerotized process of the theca, shape of the central process of left paramere, and shape and degree of dentation of the vesica. Differs from C. gracilis in the more robust body, reduced dentation of apical part of the vesica, small angle-shaped sensory lobe of the left paramere, long sclerotized process of the theca nearly reaching thecal apex.

DESCRIPTION: VESTITURE: Dorsal surface covered with a mixture of brown and silvery white long simple setae. Silvery-white setae reclinate to adpressed, located on whitish areas of dorsum, predominate on head and at sides of pronotum; dark setae longer than silvery-white setae, located on greenish areas, adpressed on forewings, scarce, erect, and contrastingly long, spinelike on head and pronotum. Inner surface of antennal segment I with two dark spinelike setae; foremargin of hind femora and apices of fore- and middle femora with dark spinelike setae. Vestiture on legs and antennae reclining, short and pale. Ventral surface covered with silver setae only.

COLORATION: Antennal segment I with incomplete brown median ring, usually also brown at base; segment II with four dark brown rings. Head and pronotum greenish to pale yellow, with indistinct whitish areas. Scutellum uniformly pale. Forewings pale whitish, frequently covered with mosaiclike, irregularly shaped greenish spots (fig. 44). Corium with conspicuous dark brown spot medioapically. Membrane transparent, laterally with large dark brown rectangular spot posterior of cells. Cells greenish to ochraceous. All femora covered with round brown spots, spots on hind femora larger, fused into transverse stripes on foremargin. Tibia with large brown dots at bases of brown to partly pale tibial spines.

MALE GENITALIA: Left paramere (figs. 25, 26) with well-developed, hooklike sensory lobe, long and thin apical process; central process large, with hooklike, inward directed apex. Right paramere simple, lanceolate, without constriction at middle. Theca (fig. 19) with two tubercles at apex; sclerotized process long, spinelike and very slightly curved. Vesica (figs. 5, 6) S-shaped, strongly curved at middle, apical strap long, somewhat flattened and apically dentate.

STRUCTURE AND MEASUREMENTS (N 3 5 1, N ♀ 5 4): Total length male 2.2, female 2.57 (2.5–2.6). Head: width male 0.54, female 0.55 (0.55); vertex width male 0.29, female 0.32 (0.30–0.33); antennal segment I male 0.25, female 0.26 (0.25–0.28); antennal segment II male 1.03, female 1.01 (1.00–1.03). Pronotum: width male 0.70, female 0.80 (0.78–0.83); length male 0.33, female 0.38 (0.38).

Body elongate oval, male 3.1 X, female 3.1– 3.4 X as long as width of pronotum; vertex male 2.3 X, female 2.4–2.9 X as wide as eye; antennal segment I short, male 0.8 X, female 0.7 X as long as pronotum; antennal segment II male 1.5 X, female 1.2–1.3 X as long as basal width of pronotum, male 1.9 X, female 1.8–1.9 X as long as width of head. Labium with slightly swollen apex of segment III and base of segment IV; reaching middle coxae. Hind femora swollen.

DISTRIBUTION: Spain ( Gravestein, 1978; Ribes, 1984), France ( Wagner and Weber, 1964), Italy ( Carapezza, 1995), Algeria ( Eckerlein and Wagner, 1965), Tunisia ( Carapezza, 1997), Libya ( Eckerlein and Wagner, 1970), Egypt ( Linnavuori, 1964), Sudan ( Wagner, 1963; Linnavuori, 1993a), Saudi Arabia ( Linnavuori, 1986), Iraq ( Linnavuori, 1993b), Israel ( Kerzhner and Josifov, 1999).

DISCUSSION: Oshanin (1910) recorded C. yersini for Tshinaz and Tashkent ( Uzbekistan). I have not been able to locate the specimens from this locality although remnants of Oshanin’s collection are kept at the Zoological Institute, Russian Academy of Sciences. However, the mentioned records seem highly doubtful, as C. yersini is so far known only from the Mediterranean area. It seems highly probable that Oshanin’s record should be referred to C. apanaskevichi , as this species is similar to C. yersini in external characters and known from Central Asia.

HOST PLANT: Tamarix spp.
