description: Peltidocylapus caudatus new species
(Figs 4b, 8f, 11g –j, 12p–u)
Diagnosis. Recognized by the following set of features: dorsum dark brown-black (Fig. 4b); antennal segment II with very narrow, white annulation apically, much narrower than half of interocular distance dorsum dark brownblack (Fig. 4b); posterior lobe of pronotum with distinct, broad swelling medially (Figs 4b, 11g); scutellum distinctly convex medially, covered with short, recumbent setae (Figs 4b, 11g, h); endosoma membranous, without any sclerites or sclerotized lobes (Figs 12 p–r); distal part of ductus seminis (dss) with broad transparent portion dorsally, which is furnished with sclerotized, elongate, longitudinal folding medially, base of dss with broad sclerotized plate (Figs 12 p–r); left paramere C-shaped, apical process thin in lateral and dorsal views, with large outgrowth baso-laterally, curved and thin in dorsal view (Figs 12s, t); right paramere sickle-shaped, with relatively long apical process (Figs 12u).
Description. Male. COLORATION (Figs 4b). Dorsum from fuscous with black areas to entirely black. Head. Black with broad yellow areas; antenna dark brown; segment I narrowly pale basally; segment II with very narrow white annulation labium dark brown to black. Thorax. Pronotum. Black. Mesoscutum and scutellum. Black. Thoracic pleura. Blackish; metathoracic scent gland evaporative areas fuscous, narrowly yellowish posteriorly. Hemelytron. Black; medial portion of clavus and subapical part of corium broadly pitchy black. Legs. Procoxa black; meso- and meta coxae fuscous dark yellow; femora dark castaneous with yellow band near apex; tibiae dark brown; tarsi dark brown. Abdomen. Dark castaneous black. TEXTURE AND VESTITURE. Head. Covered with fine, recumbent, and semi-recumbent vestiture; antennal segment I shiny, glabrous, 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. Scutellum. Covered with very short, fine, recumbent setae (Fig. 11h). Hemelytron. Covered with very short and sparse setae. STRUCTURE. Head. Antennal segment I gradually becoming broadened toward apex (Fig. 4b); segment II thin, almost cylindrical, weakly broadened apically (Fig. 4b). Thorax. Pronotum. Posterior lobe with distinct, broad swelling medially (Fig. 4b, 11g). Scutellum. With strongly convex, broad swelling medially (Fig. 4b, 11g). Abdomen. Genitalia. Endosoma membranous, without any sclerites or sclerotized lobes; distal part of ductus seminis (dss) with broad transparent portion dorsally, which is furnished with sclerotized, elongate, longitudinal folding medially, base of dss with broad sclerotized plate (Figs 12 p–r). Left paramere C–shaped, apical process thin in lateral and dorsal views, with large outgrowth baso-laterally, curved and thin in dorsal view (Figs 12s, t). Right paramere sickle-shaped, with relatively long apical process (Fig. 12u).
Measurements. (*: holotype measurements): Body. Length: 6.0*–6.6, width 2.1*–2.3. Head. Length: 0.50– 0.55*, width: 1.1*, interocular distance 0.4*. Antenna. Length of segment I: 0.64–0.66*, II: 3.25*–3.40, III: 3.6*– 4.5, IV: 3.0 (partly broken in holotype). Labium. Length of segment I: 0.95–0.97*, II: 0.98–1.00*, III: 1.00*–1.20, IV: 0.44–0.46*. Pronotum. Length: 0.95*–1.10, width of anterior margin: 1.10*–1.20, length of lateral margin: 0.95*–1.10, width of posterior margin: 2.20*–2.30.
Female. Unknown.
Etymology. The specific epithet is taken from the Latin cauda meaning tail and is used to denote the strongly developed, tail-like lateral outgrowth of the left paramere.
Biology. Unknown.
Distribution. Ecuador (Orellana), Peru (Madre de Dios).
Remarks. Most like P. calyciformis and P. parallelus in sharing scutellum with short, semi-recumbent setae. It can be, however, easily distinguished by the presence of medial, sclerotized folding on the transparent, dorsal portion of distal portion of ductus seminis inside endosoma.
