Redescription. Male: Macropterous, elongated, total length 2.7–3.2 mm. COLOURATION ( Fig. 1 ): Head: Dark brown to black, spot near eye yellowish or brownish, sometimes hardly visible; eye dark brown or brownish with yellowish hind margin; labium and antenna dark brown to black, antennal segment IV somewhat paler than other segments. Thorax: Uniformly and entirely dark brown to black. Abdomen: Dark brown to black. SURFACE AND VESTITURE: As in generic description, dorsum smooth and shiny, posterior margin of pronotum somewhat rugose. STRUCTURE AND MEASUREMENTS: Body 2.9–3.3× as long as width of pronotum. Head: Shape, position of antennal fossa and length of labium as in generic description; eye not protruding, at a small distance or in contact with anterior angles of pronotum; head 1.4–1.5× as wide as high; vertex 1.7–2.0× width of eye; antennal segment II 0.9–1.1× as long as basal width of pronotum, 0.9–1.1× as long as width of head; segments III and IV combined, as long as or shorter than segment II. Thorax: Pronotum 2.1–2.2× as wide as long and 1.0–1.1× width of head; posterior margin of pronotum straight or concave, mesoscutum partly exposed; hind femur not swollen. GENITALIA: Body of right paramere oval, apical process of left paramere slightly curved, without triangular process at base ( Fig. 5 ); theca smooth, without depression on dorsal wall ( Fig. 4 ); basal portion of ductus seminis uniformly sclerotised ( Fig. 2 ); distal portion of ductus seminis bowl-shaped, with walls around secondary gonopore equal in length ( Fig. 2 ); endosoma with more or less distinct sclerotised area apically and with single curved and twisted spicule, equal in length with dorsal wall of theca ( Fig. 4 ).

Female: Brachypterous, oval, total length 2.0– 2.2 mm. COLOURATION ( Fig. 1 ): As in male. SURFACE AND VESTITURE: As in generic description. STRUCTURE AND MEASUREMENTS: Structure as in generic description. Body 2.0–2.3× as long as width of pronotum. Head: Somewhat broader than in male, eye not protruding, in contact with anterior pronotal margin; head 1.3–1.4× as wide as high; vertex 2.3–2.6× as wide as eye; antennal segment II 0.5–0.6× as long as basal width of pronotum, 0.4–0.6× as long as width of head, segments III and IV combined, longer than segment II. Thorax: Pronotum 2.1–2.5× as wide as long and 0.9–1.0× as wide as head; posterior margin of pronotum concave, mesoscutum partly exposed; length of hemelytra ranging from reaching abdominal tergum V to reaching abdominal tergum VII, with posterior margin truncate or broadly rounded; clavus separated by shallow suture, cuneal comissure longer than scutellum. GENITALIA: Oval sclerotised ring 1/3 rd– 1/4 th width of dorsal labiate plate, sclerotised areas near sclerotised rings separated from each other, more than twice as long as sclerotised ring ( Fig. 6 ); posterior wall with a pair of triangular sclerites projecting beyond anterior margin of posterior wall ( Fig. 7 ).

Differential diagnosis. Distinguished by the macropterous male, uniformly dark femora and tibiae, apical process of left paramere without triangular process at base ( Fig. 5 ), dorsal wall of theca without a depression ( Fig. 4 ), endosoma with a single spicule and wide sclerotised area, and without denticulate areas, scleroized rings of dorsal labiate plate distinctly oval, and sclerotised area ventral to each of those rings more than twice as long as sclerotised ring ( Fig. 4 ). Similar to P. parallela , which can be distinguished in the longer body size, often femora with yellowish apices and tibiae with yellowish bases, endosoma with two spicules ( Fig. 4 ), sclerotised ring of dorsal labiate plate roundish, and smaller sclerotised area of dorsal labiae plate ( Fig. 6 ). Apparently not separable from P. phoenicea in the structure of male genitalia, but that species differs in having yellowish appendages.

Distribution. Known mainly from Mediterranean countries and Switzerland. The species has also been recorded from Turkey, Israel and the Canary Islands ( KERZHNER & JOSIFOV 1999). New for Andorra.

Discussion. This species is very similar to P. parallela in appearance. Refer to the corresponding section for P. parallela for discussion of the difficulties in separating these species.
