Camptotylus bipunctatus: Reuter, 1891: 8 .

DIAGNOSIS: Clearly recognized by the small size, color pattern, long and pale antennal segment I, comparatively short antennal segment II, shape of the sclerotized process of the theca, absence of dentation on the long and thin apical process of the vesica, shape of the left paramere. Somewhat resembles C. linae in the vestiture, enlarged antennal segment I, comparatively thin vesica and boatshaped left paramere. However, clearly distinguished by the measurements and ratios, coloration of antennal segment I and legs, presence of minute central process of the left paramere, and structure of the apical part of the vesica.

DESCRIPTION: VESTITURE: Entire dorsum covered with dense, dark, suberect to reclining simple setae and very scarce, reclining, silver simple setae. Pronotum and extreme base of forewings with contrastingly robust, erect, and at least twice as long as elsewhere dark setae. Antennal segment I with contrastingly long, erect seta at middle, pubescence on antennal segment III erect and longer than that on other antennal segments. Ventral surface only with silver simple setae.Ventral surface only with silver simple setae.

COLORATION: Antennae, head, pronotum, and scutellum uniformly pale, without dark markings. Forewings uniformly pale yellow, with dark brown roundish spot in medioapical area of corium. Membrane transparent, laterally with faint brown rectangular spot posterior to cells. Cells transparent. Hind femora apically with pale brown dots. Tibia with minute brown dots at bases of darkened tibial spines.

MALE GENITALIA: Left paramere (figs. 31, 32) of typical phyline shape. Central process greatly reduced, hooklike. Right paramere (fig. 11) elongate oval, without constriction, with comparatively long apical process. Theca (fig. 22) with dentate mouth, apex of sclerotized process broadly rounded, with subapical denticle. Vesica (figs. 8, 9) S-shaped, smoothly curved; apical strap with four rows of minute denticles, abruptly narrowed apically, slightly curved and tapering distally.

STRUCTURE AND MEASUREMENTS (N 5 2 MALES): Total length 2.0–2.1. Head: width 0.50, vertex width 0.28, antennal segment I 0.40–0.45, antennal segment II 0.73–0.78. Pronotum: width 0.68–0.70, length 0.33– 0.35 .

Body elongate oval, 3.0 X as long as width of pronotum; vertex 2.4 X as wide as eye; antennal segment I notably long and swollen, twice as thick as antennal segment II, 1.1–1.3 X as long as pronotum; antennal segment II very short, 1.1 X as long as basal width of pronotum, 1.5–1.6 X as long as width of head. Labium with slightly swollen apex of segment III and base of segment IV, hardly reaching middle coxae. Hind femora long and somewhat swollen.

DISTRIBUTION: Chimkent Prov. of Kazakhstan, extreme south of Uzbekistan, Afghanistan ( Hoberlandt, 1961).

REMARKS: The record of C. bipunctatus from Syria ( Puton, 1881a) was actually based on the specimen from Haifa ( Israel), later ( Puton, 1881b) described as C. linae . Subsequent citations of C. bipunctatus both from Syria ( Wagner, 1975) and Israel ( Linnavuori, 1961) are based on Puton (1881a) and the compilation by Bodenheimer (1937), respectively. The record of C. bipunctatus from Tajikistan ( Kiritshenko, 1964) is based on a misidentification and should be referred to C. apanaskevichi .

HOST PLANT: Unknown.

DISCUSSION: The species was described by Reuter (1879) from two specimens collected by famous Russian geographer and naturalist A.P. Fedchenko during the expedition to Turkestan. Although the fauna of Central Asia is comparatively well sampled, I have found only one additional specimen of the species, from Termez, in the collection of the Zoological Institute, Russian Academy of Sciences.

SPECIMENS EXAMINED: Holotype: KAZA- KHSTAN: South Kazakhstan Prov.: Chardara , 25 Apr 1871, Fedtshenko, 13 without USI label ( ZMMU).

Additional specimen: UZBEKISTAN: Termez [Buchara mer. 5 former Bukhara Chanate], 15 May 1912, A. Kiritshenko, 13 ( AMNH _ PBI 00140410 ) .
