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.
