Type locality. Spain, Almeria Prov., Bédar.

Material examined. SPAIN: Valenciana: [Sierra de] Bédar, Prov. Almeria, 37.18333°N 1.98333°W, 100 m, 27 Apr 2001, H. Günther, 2 JJ (AMNH_PBI 00337182, AMNH_PBI 00337183) ( NHMM), 2 JJ (AMNH_PBI 00334229,AMNH_PBI 00337441), 2♀♀ (AMNH_PBI 00334230,AMNH_PBI 00337442) ( ZISP), 1J (AMNH_PBI 00340290), 1 ♀ (AMNH_PBI 00340291) ( ZMUH).

Redescription. Male: Relatively large, 5.0– 5.6 mm. COLOURATION ( Fig. 16 ): Dorsum dirty yellowish to pale brown. Head: Clypeus with black longitudinal spot at base and two black lateral stripes extending from base to middle of clypeus; mandibular plate entirely pale, maxillary plate darkened at apex; frons with black, not confluent stripes radiating from midline; vertex with two black, not confluent spots, rarely also with brown minute spots; antenna dark brown to black, sometimes antennal segment I paler than others; labium brown, apex of segment IV black. Thorax: Pronotal collar darkened medially; calli covered with largely confluent black spots; disc entirely pale brown or pale brown apically and brown basally; scutellum pale brown to brown with pale brown midline, and sometimes with brown minute spots; thoracic pleurites dirty yellowish. Hemelytron: Clavus, corium and cuneus uniformly pale brown. Legs: Pale-brown with reddish tinge, femora with a series of minute, partly confluent dark brown spots running along posterior margin at base and apically extending to anterior margin. Abdomen: Dorsally brown, ventrally pale brown. SURFACE AND VESTITURE: Smooth, disc finely rugose, with shallow, sometimes indistinct, usually darkened punctures; scutellum with transverse wrinkles. Vestiture composed of intermixed simple setae and silvery scales; simple setae usually black and extremely short everywhere on dorsum, rarely pale on head. STRUCTURE: Head: Vertex 2.2–2.6 × as wide as eye; antennal segment I 0.4–0.5 × as long as width of head; antennal segment II 1.5–1.6 × as long as width of head and 1.1–1.2 × as long as width of pronotum. Thorax: Pronotum 1.6–1.8 × as wide as long and 1.3–1.4 × as wide as head; disc extremely convex. GENITALIA: Genital capsule with large tooth on left side of genital opening ( Fig. 32 ); sensory lobe of left paramere flattened, apically widened and serrate, caudal process short, thick and serrate ( Fig. 44 ); right paramere as in Fig. 39; left spicule of aedeagus long and thin, slightly curved, with denticles on the top; one of the branches of right spicule long and thin with apical serration and basal tooth, another branch broad and curved, with serrate apical margin (Fig. 56).

Female: Relatively large, 5.2 mm. COLOURATION ( Fig. 17 ): as in male, but dark minute spots on vertex usually better expressed. SURFACE AND VESTITURE: As in male. STRUCTURE:Almost of the same size as male, with larger interocular distance, vertex 2.7–2.9 × as wide as eye; antennal segment I 0.4 × as long as width of head; antennal segment II 1.3–1.4 × as long as width of head and 1.0–1.1 × as long as width of pronotum; pronotum 1.7 × as wide as long and 1.2–1.3 × as wide as head; abdomen larger and usually partly extending beyond apex of membrane; membrane reaching at least base of segment IX.

Differential diagnosis. Distinguished by the following combination of characters: dark minute spots on pronotum and hemelytron absent; two black spots on vertex not confluent ( Fig. 16–17 ); vestiture on dorsum composed of silvery scales and very short simple setae, uniformly dark everywhere except head; genital capsule with large tooth on left side of genital opening ( Fig. 32 ); sensory lobe of left paramere flattened, apically widened and serrate, caudal process short, thick and serrate ( Fig. 44 ); left spicule of aedeagus long and thin, slightly curved, with denticles on the top; one of the branches of right spicule long and thin with apical serration and basal tooth, another branch broad and curved, with serrate apical margin (Fig. 56). Clearly differs from all other species in combination of large body size and presence of small black setae on thorax and hemelytron in absence of dark minute spots; male specimens also clearly differs in peculiar shape of vesical spicules.

Host associations. BAENA & GÜNTHER (2001) and GÜNTHER et al. (2007) record the host plant as Ephedra fragilis Desf.

Distribution. So far known exclusively from the type locality, Almeria Prov., Spain (Fig. 19) ( BAENA & GÜNTHER 2001, GÜNTHER et al. 2007).
