description: Peltidocylapus parallelus, new species
(Figs 5c, 11l, 13m –r, 19a–c, 20g, 21i, q)
Diagnosis. 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).
