(Figs 5b, 13g –l)
Diagnosis. Recognized by the following set of features: hemelytron yellow with large dark castaneous patch at apical half of clavus and apical one-third of corium (Fig. 5b); antennal segment II with white annulation on apex that is much narrower than half of interocular distance (Fig. 5b); sclerotized, distal portion of ductus seminis inside endosoma (dss) relatively short, broadened toward apex (Figs 13g –i); base of dss with broad and long sclerotized plate (Figs 13g); portion beneath dss entirely occupied by sclerotized, serrate lobe (Figs 13g, h); left paramere apical process with large outgrowth originating from baso-dorsal portion; apical process massive, long, and weakly arcuate in dorsal view (Figs 13 j, k).
Redescription. Male. COLORATION (Fig. 5b). Dorsum dark castaneous-yellow. Head. Fuscous dark castaneous with large yellow areas; antennal segment I dark red, tinged with yellow; segment II dark brown, narrowly yellow basally and apically; segments III and IV dark brown; labial segments I and II dark castaneous; segment II largely tinged with yellow apically; segment III yellow; segment IV fuscous, narrowly tinged with yellow basally.
Thorax. Pronotum. Dark castaneous. Mesoscutum and scutellum. Dark castaneous; scutellum with two large yellow patches each situated baso-laterally. Thoracic pleura. Dark castaneous; metathoracic scent gland evaporative areas reddish, weakly tinged with fuscous, with yellow stripe along posterior margin. Hemelytron. Yellow with large dark castaneous patch at apical half of clavus and apical one-third of corium; clavus dark brown; membrane grey. Legs. Procoxa dark castaneous; meso- and metacoxae yellow; hindleg dark yellow; metafemur tinged with brown apically; remaining legs missing. Abdomen. Dark red, tinged with dark yellow. TEXTURE AND VESTITURE (Fig. 5b). Thorax. Scutellum. Covered with relatively long, semi-recumbent and erect setae. Hemelytron. Covered with short, semi-recumbent setae. STRUCTURE (Fig. 5b). Thorax. Pronotum. Posterior lobe flat. Scutellum. With moderately convex, broad, longitudinal swelling medially. Abdomen. Genitalia. sclerotized, distal portion of ductus seminis inside endosoma (dss) relatively short, broadened toward apex (Figs 13g –i); base of dss with broad and long sclerotized plate (Figs 13g); portion beneath dss entirely occupied by sclerotized, serrate lobe (Figs 13g, h); left paramere apical process with large outgrowth originating from baso-dorsal portion, apical process massive, long, and weakly arcuate in dorsal view (Figs 13 j, k).
Measurements. Holotype ♂. Body. Length: 4.5, width 1.55. Head. Length 0.4, width 0.87, interocular distance 0.27. Antenna. Length of segment I: 0.4, II: 1.57, III: 1.60, IV (partly broken). Labium. Length of segment I: 0.63, II: 0.70, III: 0.70, IV: 0.47. Pronotum. Length: 0.70, width of anterior margin: 0.66, length of lateral margin: 0.73, width of posterior margin: 1.43.
Female. Unknown.
Etymology. The specific epithet is taken from the Latin pallidus meaning pale and is used to denote the large pale patch on base of hemelytron.
Biology. Unknown.
Distribution. Peru (Madre de Dios).
Remarks. Most like P. calyciformis, P. caudatus, P. ecuadorensis, P. parallelus, P. rugosus, P. scutellaris, P. simplex, and P. spinosus in sharing the broad, convex swelling in the middle of scutellum (Figs 4a, b, d, 5b, c, 6). It can be easily distinguished by the small body (<5.0 mm) and the pale patch on basal half of corium (Fig. 5b)
Type material. Holotype ♂: Peru: Madre de Dios, Manu National Park, at UV light trap, 15 Aug 1980 – 30 Nov 1981, Charles H. Janson collectors; gift from The Burke Museum, mounted from alcohol 1986; CASENT 8420153 (CAS).
