Megalobasis bipunctatus View in CoL (non Reuter, 1879): Puton, 1881a:

126 Misidentification (see C. bipunctatus for details) Megalobasis linae Puton, 1881b: 84 . Camptotylus linae: Reuter, 1891: 9 . Camptotylus aphidoides Jakovlev, 1881: 199 (syn. by

Reuter, 1885: 159).

DIAGNOSIS: Clearly recognized by the large size, long antennal segments I and II, brown stripes along foremargins of all femora, vestiture, shape of the vesica, and absence of central process of the left paramere. Similar in length of antennal segment I to C. bipunctatus , although it has pale antennae, while the first segment in C. linae is entirely darkened. Somewhat similar to C. meyeri in the darkened antennal segment I and presence of stripes on femora, but clearly distinguished from this species by the absence of scalelike setae, structure of the male genitalia, and almost all ratios and sizes.

DESCRIPTION: VESTITURE: Entire dorsum covered with mixture of dense, dark simple setae and scarce, reclining silver simple setae. Head, pronotum, exposed part of mesonotum, apices of fore- and middle femora, and foremargin of hind femora with contrasting long and robust, erect simple dark setae similar in structure and size to tibial spines. Two setae of same structure located at middle of antennal segment I. Forewings with dense, simple adpressed dark setae one-third to one-half as long as those on head and pronotum. Vestiture on legs and antennae reclining to suberect; pubescence on antennal segment III usually erect and longer than that on other antennal segments. Entire ventral surface with silver simple setae.

COLORATION: Dorsal surface (fig. 40) pale greenish; head and pronotum with indistinct yellowish markings. Antennal segment I uniformly dark brown to black; extreme base and apex of antennal segment II, segments III and IV usually slightly darkened. Medioapical area of corium with conspicuous dark roundish spot; membrane transparent, with brown at apex, along outer vein, and apices of cells. Foremargins of all femora with brown stripe. Hind femora with stripes along both fore- and hind margins. Ventral surface of middle femur with round brown spot at middle; ventral surface of hind femur with similar large spot and a series of five smaller spots. Tibiae with large brown dots at bases of dark tibial spines. Ventral surface uniformly pale.

MALE GENITALIA: Left paramere (fig. 34) of typical structure, without central process. Right paramere simple, elongate oval, not constricted at middle. Apex of theca (fig. 16) thin; sclerotized process swordlike, located at some distance from apex of theca, thin and smoothly curved. Vesica (fig. 10) C-shaped, smoothly curved; apical strap straight, only extreme apex curved and dentate.

STRUCTURE AND MEASUREMENTS: Total length male 2.75 (2.6–2.8), female 2.63 (2.4– 2.8). Head: width male 0.56 (0.55–0.58), female 0.56 (0.55–0.58); vertex width male 0.30 (0.30), female 0.30 (0.29–0.31); antennal segment I male 0.61 (0.53–0.65), female 0.48 (0.45–0.50); antennal segment II male 1.53 (1.43–1.63), female 1.33 (1.28–1.38). Pronotum: width male 0.79 (0.75–0.83), female 0.80 (0.78–0.83); length male 0.41 (0.40–0.43), female 0.44 (0.43–0.48).

Body almost parallel-sided, distinctly oblong in males, more stout in females; male 3.4–3.7 X, female 3.1–3.4 X as long as width of pronotum; vertex male 2.2–2.4 X, female 2.2–2.4 X as wide as eye; antennal segment I remarkably long and swollen, male 1.2–1.6 X, female 1.0–1.2 X as long as pronotum; antennal segment II notably long, male 1.7–2.1 X, female 1.6–1.7 X as long as basal width of pronotum, male 2.5–2.9 X, female 2.3–2.5 X as long as width of head. Labium reaching middle coxae, segments III and IV not swollen. Hind femora long and somewhat swollen.

DISTRIBUTION: Israel ( Puton, 1881b), Jordan ( Wagner, 1975), Asian Turkey ( Hoberlandt, 1956), Iran * ( Azerbaijan: Khoda Alafin Station Tatar; Matocq, personal commun.), Azerbaijan ( Gidayatov and Atakishieva, 1972), Georgia (Zaitseva, 1988), Armenia *, Ukraine, southern part of European Russia (Dagestan, Chechnya).
