description
Description. Coloration. Body mostly brown with dark brown or whitish brown to pale brown markings (Fig 1). Surface and vestiture. Body mostly smooth or slightly shiny, without punctures or rugosity. Body clothed mostly with adpressed and suberect pale setae, mostly longer than tibia width; setae on pleura and legs adpressed and shorter than tibia width (Figs 2 D, J, L, 4 B, E, K). Structure and measurements. Body elongate (Fig. 1 A). Head. Horizontal, dorsally as long as wide, vertex not carinate, not covering anteromedial margin of pronotum posteriorly; eye not protruding laterally (Figs 2 D, 4 B); in anterior view head wider than high, base of clypeus placed above ventral margin of eye and antennal fossa, antennal fossa placed above ventral margin of eye, but below eye’s middle line (Figs 2 A, 4 A); in lateral view head as long as or slightly longer than high, base of clypeus not delimited with depression, buccula reaching eye, distance between buccula and pronotum as long as or longer than buccula length; eye large, extending to ventral margin of head; eye slightly covering anterolateral margin of pronotum; antennal fossa adjacent to eye and placed close to suture between mandibular and maxillary plates (Figs 2 G, 4 I); antenna shorter than body, antennal segment I not widened, distinctly shorter than head width; segment II cylindrical, as wide as segment I, longer than head width, segment III slightly thinner than segment II; segment IV as long as segment III (Figs 2 D, H, 4 B, L); labium reaching abdominal segments VI – IX; labial segment I surpassing base of forecoxa, distinctly subdivided in apical half (Figs 2 I, 4 G); segment II slightly longer than segment I, distinctly subdivided subapically, its apical part 2 – 3 × as long as wide (Fig. 2 B, E, 4 C); segment III as long as or slightly shorter than segment II, more than 10 × as long as wide; segment IV subequal to 1 / 2 – 2 / 3 of segment III, subdivided (Figs 2 N, 4 H). Thorax. Collar flattened, delimited dorsally by a fine line; calli indistinct; posterior margin of pronotum weakly concave (Figs 2 D, 4 B), lateral margins not carinate (Figs 2 G, 4 I), propleural suture T-shaped (Figs 2 G, 4 I); mesoscutum distinctly exposed, scutellum flat (Figs 2 J, 4 E); mesepimeral apodeme slit-like; mesepimeral spiracle open, slit-like, with distinct microsculpture along anterior margin dorsally; metathoracic scent gland evaporative area triangular, its dorsal margin concave, peritreme slightly upraised, rounded, metepimeron narrow (Figs 2 L, 4 K). Hemelytron. Claval commissure 1.5 – 2 times as long as scutellum; corial fracture almost reaching middle of corium or slightly surpassing it; embolium distinctly delimited in basal 2 / 3; cuneus delimited with distinct fracture, not notched; membrane with two cells, forming right angle, distance between cell and membrane apex longer than cell length (Figs 2 J, K, 4 E, F). Legs. Forecoxa shorter than pronotum length, subequal to middle and hind coxae in length and width; forefemur 4 × as long as wide, as wide as and as long as middle femur; hind femur twice as wide as and slightly longer than forefemur (Figs 2 M, O, 4 M); tarsus three-segmented, segments subequal in length or segment I slightly shorter than segment II (Figs 2 F, 4 D); pretarsal claws with apical tooth, parempodia setiform (Figs 2 C, 4 J). Male genitalia. Genital capsule distinctly tapering posteriorly (Figs 3 F, 6 C), right paramere widened basally, its apical part slightly curved (Figs. 3 D, 5 D), ductus seminis as long as phallotheca, mostly coiled, its apical part narrowly sclerotized around secondary gonopore; endosoma not subdivided into vesica and conjunctiva (Figs 3 A – C, 5 A, B). Female genitalia. See description of P. dryander.
diagnosis
Diagnosis. Head more or less prognathous, as long as high in lateral view (Figs 2 G, 4 I); macropterous, hemelytron elongate, its lateral margins almost parallel (Fig. 1 A), claval commissure 1.5 – 2 times as long as scutellum (Figs 1 A, 2 J, 4 E); antennal fossa placed near suture (not above) between mandibular and maxillary plates; eye reaching ventral margin of head, adjacent to pronotum and covering its anterolateral margin; buccula reaching eye (Figs 2 G, 4 I); labium reaching at least middle of abdomen; vertex not carinate (2 D, 4 B); lateral margin of pronotum not carinate (Figs 2 G, 4 I); antenna shorter than body; collar flattened, separated by fine line; calli flat, obsolete (Figs 2 D, 4 B); body impunctate, clothed in simple setae only, microsetae are hair-like, not modified; metathoracic scent gland evaporative area triangular, almost reaching base of hind coxa (Figs 2 L, 4 K); labial segments I, II and IV subdivided (Figs 2 B, E, I, N, 4 C, G, H); forefemora not modified (Figs 2 O); cuneus delimited with distinct fracture, only slightly longer than wide at base (Figs 2 K, 4 F); segments of hind tarsus either subequal in length, or segment I slightly shorter than segments II and III each (Figs 2 F, 4 D).
etymology
