Peltidocylapus parallelus , new species
( Figs 5c View FIGURE 5 , 11l View FIGURE 11 , 13m –r View FIGURE 13 , 19a–c View FIGURE 19 , 20g View FIGURE 20 , 21i, q View FIGURE 21 )
Diagnosis. Recognized by the following set of features: dorsum dark brown black ( Fig. 5c View FIGURE 5 ); antennal segment II with white annulation on apex that is much narrower than half of interocular distance ( Fig. 5c View FIGURE 5 ); posterior lobe of pronotum with distinct, broad swelling medially ( Fig. 5c View FIGURE 5 ); scutellum distinctly convex ( Fig. 5c View FIGURE 5 ), covered with very short, semi-recumbent setae ( Fig. 11l View FIGURE 11 ); endosoma membranous, with small sclerotized lobe apically ( Figs 13m –o View FIGURE 13 ); distal sclerotized portion of ductus seminis short, not caliciform, lateral margins almost parallel ( Fig. 13m, o View FIGURE 13 ); base of dss with small sclerotized plate ( Fig. 13m View FIGURE 13 ); left paramere apical process relatively thick, weakly arcuate, with well-developed lateral outgrowth that is broad, long, weakly arcuate ( Figs 13p, q View FIGURE 13 ); dorsal labiate plate with sclerotized rings paired, kidney-shaped, large, occupying most of bursa copulatrix ( Figs 19a, b View FIGURE 19 ); ventral labiate plate with broad, club-like sclerotization ( Fig. 19c View FIGURE 19 ).
Description. Male. COLORATION ( Fig. 5c View FIGURE 5 ). 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 View FIGURE 5 ). Thorax. Scutellum. Covered with very sparse, irregular, erect and semi-recumbent setae. Hemelytron. Covered with short, semi-recumbent setae. STRUCTURE ( Fig. 5c View FIGURE 5 ). 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 View FIGURE 13 ); distal sclerotized portion of ductus seminis short with lateral margins almost parallel ( Fig. 13m, o View FIGURE 13 ); base of dss with small, sclerotized plate ( Fig. 13m View FIGURE 13 ); left paramere apical process relatively thick, weakly arcuate, with well-developed lateral outgrowth that is broad, long, weakly arcuate ( Figs 13p, q View FIGURE 13 ); right paramere sickle-shaped, apical process relatively short ( Fig. 13r View FIGURE 13 ).
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 View FIGURE 19 ); ventral labiate plate with broad, club-like sclerotization ( Fig. 19c View FIGURE 19 ).
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 View FIGURE 11 ). It can be distinguished by the distal portion of ductus seminis inside endosoma nearly rectangular with almost parallel lateral margins ( Fig. 13m, o View FIGURE 13 ).
