Recognized by the following set of features: dorsum dark brown black ( Fig. 5c ); antennal segment II with white annulation on apex that is much narrower than half of interocular distance ( Fig. 5c ); posterior lobe of pronotum with distinct, broad swelling medially ( Fig. 5c ); scutellum distinctly convex ( Fig. 5c ), covered with very short, semi-recumbent setae ( Fig. 11l ); endosoma membranous, with small sclerotized lobe apically ( Figs 13m –o ); distal sclerotized portion of ductus seminis short, not caliciform, lateral margins almost parallel ( Fig. 13m , o ); base of dss with small sclerotized plate ( Fig. 13m ); left paramere apical process relatively thick, weakly arcuate, with well-developed lateral outgrowth that is broad, long, weakly arcuate ( Figs 13p, q ); dorsal labiate plate with sclerotized rings paired, kidney-shaped, large, occupying most of bursa copulatrix ( Figs 19a, b ); ventral labiate plate with broad, club-like sclerotization ( Fig. 19c ). Description. Male. COLORATION ( Fig. 5c ). Dorsum dark brown to black to entirely black with indistinct, small yellowish areas. Head . Fuscous, tinged with yellow; antenna fuscous; antennal segment I weakly and narrowly tinged with yellow basally; segment II weakly tinged with dark yellow basally and with white indistinct, narrow annulation apically; labium dark brown to black. Thorax . Pronotum, mesoscutum, scutellum, and hemelytron . Uniformly black; scutellum sometimes weakly tinged with dark brown medial and with small yellowish patch apically. Thoracic pleura . Dark brown to black; metathoracic scent gland evaporative area dark brown its posterior portion contrastingly yellow. Abdomen . Black tinged with dark brown. TEXTURE AND VESTITURE ( Fig. 5c ). Thorax . Scutellum . Covered with very sparse, irregular, erect and semi-recumbent setae. Hemelytron . Covered with short, semi-recumbent setae. STRUCTURE ( Fig. 5c ). Thorax . Pronotum . Posterior lobe with well-developed swelling medially. Scutellum . Scutellum with strongly convex, broad longitudinal swelling medially. Abdomen . Genitalia . Endosoma membranous, with small, sclerotized lobe apically ( Figs 13m –o ); distal sclerotized portion of ductus seminis short with lateral margins almost parallel ( Fig. 13m , o ); base of dss with small, sclerotized plate ( Fig. 13m ); left paramere apical process relatively thick, weakly arcuate, with well-developed lateral outgrowth that is broad, long, weakly arcuate ( Figs 13p, q ); right paramere sickle-shaped, apical process relatively short ( Fig. 13r ). Female. Like male in coloration, structure, texture, and vestiture. Genitalia . Bursa copulatrix with sclerotized rings paired, kidney-shaped, large, occupying most of bursa copulatrix ( Figs 19a, b ); ventral labiate plate with broad, club-like sclerotization ( Fig. 19c ). Measurements . ( ♂ / ♀ , *: holotype measurements): Body . Length: 5.6*–5.9/6.3, width 1.85*–2.1/2.2–2.5. Head . Length. 0.5*–0.55/0.55, width: 1.1*/1.15, interocular distance 0.40*/0.4–0.43. Antenna . Length of segment I: 0.56*–0.60/0.57–0.62, II: 2.55*/2.5–2.6, III: 4.0*/3.75–4.5, IV: 3.75*/3.25–4.0. Labium . Length of segment I: 0.76–0.875*/0.9, II: 0.82*–0.875/0.95, III: 0.82*–0.86/0.85, IV: 0.4*/0.47. Pronotum . Length. 0.95–1.05*/1.0, width of anterior margin: 0.95*–1.1/1.1–1.15, length of lateral margin: 0.95*/0.96, width of posterior margin: 2.0*– 2.05/2.15. Etymology . The specific epithet is used to denote the distal part of ductus seminis with nearly parallel lateral margins. Biology . Unknown. Distribution . Ecuador , Guyana ( Upper Demerara-Berbice ). Remarks . Most like P. calyciformis and P. parallelus in sharing scutellum with short, semi-recumbent setae ( Fig. 11h ). It can be distinguished by the distal portion of ductus seminis inside endosoma nearly rectangular with almost parallel lateral margins ( Fig. 13m , o ). Type material . Holotype ♂ .
