description: Peltidocylapus calyciformis new species
(Figs 4a, 7d, 8e, 11k, 12j–o, 18a)
Diagnosis. Recognized by the following set of characters: dorsum dark brown-black (Fig. 4a); antennal segment II with white annulation on apex that is much narrower than half of interocular distance (Fig. 4a); posterior lobe of pronotum with distinct, broad swelling medially (Fig. 4a); scutellum distinctly convex (Fig. 4a), covered with short recumbent setae (as in Fig. 11h); endosoma membranous with serrate lobe subapically (Figs 12j, l); distal part of ductus seminis (dss) broad, caliciform with broad transparent portion dorsally, sclerotized plate at base of dss relatively small, weakly elongate (Figs 12j, k); left paramere C-shaped, apical process relatively broad, with large outgrowth baso-laterally, weakly arcuate and broadened in dorsal view, sensory lobe moderately developed, weakly pointed (Figs 12m, n); right paramere with moderately long apical process and weakly developed sensory lobe (Fig. 12o); bursa copulatrix largely membranous; seminal depository membranous, broadly developed; ringed gland apparently absent (Fig. 18a); sclerotization of ventral labiate plate broad, tapering towards its posterior part.
Description. Male. COLORATION (Fig. 4a, 7d). Dorsum dark brown to black. Head. Varying from dark brown with developed dark yellow mottling to entirely black; antennal segment I dark brown, narrowly whitish basally; segment II dark yellow on basal half, dark brown on apical half to entirely dark brown, always with narrow whitish annulation on extreme apex; antennal segments III and IV dark brown; labium dark brown to black. Thorax. Pronotum. Black. Mesoscutum and scutellum. Black. Thoracic pleura. Black; metathoracic scent gland evaporative areas fuscous, contrastingly yellow at posterior one-fourth. Hemelytron. Dark brown with indistinct yellow tinge on clavus and middle of corium; cuneus with contrastingly yellow stripe along basal margin; membrane fuscous, veins darker. Legs. Procoxa dark castaneous to black; meso- and meta coxae yellow broadly tinged with dark castaneous or dark brown; femora black with yellow band near apex; tibiae dark brown; tarsi dark brown, weakly tinged with yellow. TEXTURE AND VESTITURE (Figs 4a, 7d). Head. Covered with fine, recumbent, and semi-recumbent setae; antennal segment I shiny, glabrous, only with two to three short, stiff, erect setae apically; segment II almost glabrous with fine, sparse setae on apical part; segments III and IV covered with rather sparse, fine, semi-recumbent setae, segment IV with setae denser than segment III; labium covered with fine, semi-recumbent, relatively dense setae. Thorax. Pronotum. Covered with very fine, short, recumbent setae. Mesoscutum and scutellum. Covered with short semi-recumbent setae. Hemelytron. Covered with sparse setae. STRUCTURE. Head. Antennal segment I weakly broadened toward apex; segment II thin, almost two times thinner than segment I, cylindrical (Figs 4a, 7d). Thorax. Pronotum. Posterior lobe with distinct, broad swelling medially (Fig. 4a, 7d). Scutellum. With broad, strongly convex, longitudinal swelling medially (Fig. 4a, 7d). Abdomen. Genitalia. Endosoma membranous with relatively large, sclerotized, serrate lobe subapically (Figs 12j–l); distal part of ductus seminis (dss) broad, caliciform with broad transparent portion dorsally, base of dss with small sclerotized plate (Figs 12j–l); ductus seminis short and thick (Fig. 12l); left paramere C-shaped, apical process relatively broad, with large outgrowth baso-laterally, weakly arcuate and broadened in dorsal view (Figs 12m, n); sensory lobe moderately developed, weakly pointed (Figs 12m, n); right paramere sickle-shaped with weakly developed sensory lobe (Fig. 12o).
Female. Like male in coloration, texture, vestiture, and structure. Genitalia. Bursa copulatrix largely membranous (Fig. 18a); seminal depository membranous, broadly developed (Fig. 18a); ringed gland absent; sclerotization of ventral labiate plate broad, tapering towards its posterior part.
Measurements. (♂ / ♀, *: holotype measurements): Body. Length: 5.6–6.6*/6.4, width 2.0*–2.1/2.1. Head. Length: 0.5–0.56/0.5, 0.55*, width: 1.1–1.2*/1.1, interocular distance 0.4–0.5* /0.4. Antenna. Length of segment I: 0.65–0.70 /0.45, 0.56*, II: 2.8–3.0, 2.95*, III: 4.3–4.5 /4.1, 4.25*, IV: 3.0*–3.5. Labium. Length of segment I: 0.8–0.95*/0.95, II: 0.86–0.87*/1.0, III: 0.83*–0.96/0.9, IV: 0.4–0.43*/0.45. Pronotum. Length: 0.86–1.0*/0.85, width of anterior margin: 1.0–1.1*/0.95, length of lateral margin: 0.9–1.0*/0.95, width of posterior margin: 1.96– 2.25*/2.25.
Etymology. The specific epithet is taken from the Greek words calyx meaning cup and forma meaning shape and is used to the denote cup-like structure of the distal part of ductus seminis.
Biology. Unknown
Distribution. Ecuador (Orellana), Peru (Madre de Dios).
Remarks. Most like P. caudatus and P. parallelus in sharing the scutellum covered with short, semi recumbent setae. It can be distinguished by the distal portion of ductus seminis inside endosoma (dss) caliciform, without any folding on the medial, transparent portion of dorsal part of dss.
