Diagnosis. Recognized by the following combination of characters: dorsum pale yellow, with dark brown medial longitudinal band on hemelytra, sometimes poorly expressed on clavus and corium but always distinct on membrane ( Figs. 3–4 ); dorsum with silvery setae only, without darkened ones; dark minute spots on dorsum and legs absent, rarely darkened medial band with a few indistinct dark brown spots; vesica with long and blunt, apically dentate blade and well developed subapical step-like narrowing ( Figs. 11–13 ).

This species easily differs from all congeners in having longitudinal dark medial band on hemelytra. Color pattern of hemelytra in Solenoxyphus spp. consists of a pale yellow to slightly darkened color overlaid with dense, minute and more or less round brown spots. The only exception is S. candidatus ( Reuter, 1879) , which has more or less expressed transverse pale brown band at apex of corium (Figs. 66, 67 in Konstantinov 2008a). The latter species easily differs from S. vittiger in the color pattern of membrane, transparent basally, more or less darkened apically and devoid of the longitudinal brown band, the structure of the head, weakly projecting ventrally below inferior margin of eyes, the short labium barely reaching middle coxa, the hemelytra in female far surpassing apex of abdomen, and the structure of the vesica with acute apical blade and numerous denticles proximal to secondary gonopore ( Fig. 1 in Konstantinov 2008a). Solenoxyphus vittiger is somewhat similar to S. asanovae (Vinokurov, 1995) and S. salsolae Konstantinov, 2008 in having the characteristically blunt, apically dentate blade of vesica (compare Fig. 13 and Figs. 3, 4 , 37–39 in Konstantinov 2008a). However both these species clearly differ from S. vittiger in sizes, body proportions and coloration.

Redescription. Male: COLORATION ( Fig. 3 ): Dorsum, thoracic pleura, hemelytron, abdomen and appendages uniformly pale whitish-yellow; labium pale yellow with darkened apical two-thirds of segment IV; pronotum and scutellum frequently with pale whitish midline; tarsal segments III slightly darkened apically; medial margin of hemelytron with longitudinal pale brown stripe, viz. inner margin of clavus, medioapical area of corium, and central part of membrane more or less darkened, typically pale brown, reminder of clavus and corium, entire cuneus uniformly yellow, exocorium frequently whitish yellow, membrane at sides of brown stripe always milky whitish; sometimes darkened part of clavus and corium with minute and indistinct pale brown spots at bases of simple setae.

SURFACE AND VESTITURE: Dorsum shiny, smooth, with dense, somewhat curved adpressed simple setae, brown on medial darkened stripe and on cuneus, silver elsewhere; tibial spines whitish, rarely pale brown.

STRUCTURE: Elongate, parallel-sided, total length 3.8–4.8 mm, body 3.4–4.0 × as long as basal width of pronotum. Head: Strongly projecting anteriorly and ventrally; eyes relatively small, vertex 1.3–1.6 × as wide as dorsal width one eye; antennal fossa contiguous to inferior angle of eye, second antennal segment 0.9–1.0 × as long as basal width of pronotum, 1.2–1.3 × as long as width of head; labium reaching or slightly surpassing apex of hind coxa. Thorax: Pronotum 2.1–2.4 × as wide as long; calli slightly raised; metathoracic scent-gland evaporative area narrowly triangular, with somewhat extended dorso-posterior angle. Legs: Long and slender, tarsus thin, segment III slightly longer than segments II combined, claw long and slender, pulvillus small, not surpassing midpoint of claw, attached to claw along entire length.

MALE GENITALIA: Genital capsule: About 30 % of total area of abdomen, elongated, without keel or distinctive ornamentation. Parameres: Shape typical for Phylini , right paramere broadly oval, with contrastingly long and thin, straight apical process ( Fig. 24 ); left paramere as in Figs. 22 and 23 , with triangular, gradually tapering sensory lobe and straight apical process. Apex of theca: As in Fig. 21 . Vesica: S-shaped, long and thin; secondary gonopore subapical, with well-developed sculpture and a few comparatively large teeth laterally; apex of vesica distal of secondary gonopore with distinct step-like narrowing at base of apical blade ( Figs. 11–13 ); apical blade long, with somewhat curved apex covered with minute teeth and not pointed, distinctly longer than width of vesica proximal to secondary gonopore.

Female. COLORATION, SURFACE AND VESTITURE ( Fig. 4 ): Similar to male; longitudinal pale brown medial stripe on hemelytron frequently less distinct, sometimes clearly expressed only on membrane.

STRUCTURE: Similar to male but shorter, total length 3.7–3.9 mm, body 3.2–3.4 × as long as width of pronotum. Head: With somewhat wider vertex than in male; vertex 1.6–1.8 × as wide as dorsal width one eye; second antennal segment 0.7–0.8 × as long as basal width of pronotum, equal in length to width of head; labium surpassing apex of hind coxa and usually reaching base of ovipositor. Thorax: Pronotum 2.1–2.3 × as wide as long.

FEMALE GENITALIA: Dorsal labiate plate with small, strongly upturned dorsally sclerotized rings and a pair of thin symmetric sclerites running from each sclerotized ring to central part of labiate plate ( Fig. 29 ); sclerotized ring roughly triangular, with small, weakly sclerotized medial extension ( Fig. 34 ); sclerites encircling vulva symmetric, of typical phyline shape; vestibulum entirely membranous; posterior wall ( Fig. 36 ) with distinct lancetshaped sclerites at sides; first valvula finely serrate and gradually tapering, second valvula somewhat sagittate.

Host. Unknown.

Distribution. This species is known from deserts and semideserts of Central Asia and currently reported from all five Central Asian countries ( Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, and Uzbekistan) and northern Iran ( Konstantinov & Namyatova 2008).
