Peltidocylapus ecuadorensis new species

( Figs 4d , 13a–f , 18b–d , 21h, p )

Diagnosis. Recognized by the following set of characters: dorsum dark brown-black ( Fig. 4d ); antennal segment II with white annulation on apex that is much narrower than half of interocular distance ( Fig. 4d ); posterior lobe of pronotum with distinct, broad swelling medially ( Fig. 4d ); scutellum distinctly convex, with long, dense, erect setae ( Fig. 4d ); endosoma membranous ( Figs 13a–c ); distal part of ductus seminis (dss) broad, caliciform with broad transparent portion dorsally, base of dss with broad sclerotized plate ( Figs 13a ); left paramere C-shaped, apical process relatively broad, with large outgrowth baso-laterally, weakly arcuate and broadened in dorsal view ( Figs 13d, e ), sensory lobe moderately developed, weakly pointed ( Fig. 13d ); right paramere with moderately long apical process and weakly developed sensory lobe ( Fig. 13j ); bursa copulatrix ovoid ( Fig. 18b, c ); sclerotized rings large, kidney-shaped and occupying most of bursa copulatrix ( Figs 18b, c ); sclerotization of ventral labiate plate broad, nearly triangular ( Fig. 18d ).

Description. Male. COLORATION ( Fig. 4d ). Dorsum dark brown to black. Head. Fuscous, broadly tinged with yellow; antenna dark brown; segment I tinged with dark yellow, narrowly yellow basally; labium dark brown to black; segment I broadly tinged with yellow. Pronotum. Black. Mesoscutum and scutellum. Black; scutellum dark brown medially, with indistinct, dirty yellow tinge on basolateral angle. Thoracic pleura. Dark brown; metathoracic scent gland evaporative areas fuscous, broadly tinged with yellow posteriorly. Hemelytron. Dark brown to black. Legs. Procoxa dark brown; meso- and metacoxae yellow, tinged with dark brown; femora, tibiae, and tarsi dark brown; each femur with yellow band near apex; metafemur broadly tinged with yellow basally. Abdomen. Dark brown-black tinged with yellow. TEXTURE AND VESTITURE ( Fig. 4d ). Head. Covered with fine, short, sparse, semi-recumbent and erect setae; antennal segment I shiny, with a few fine, stiff, erect setae, being denser apically; segment II very sparse, semi-recumbent, short, fine setae being denser apically. Thorax. Scutellum. Covered with long, dense, erect setae (as in Fig. 11l ). Hemelytron. Covered with short, fine, semi-recumbent setae. STRUCTURE ( Fig. 4d ). Thorax. Pronotum. Posterior lobe with broad swelling medially. Scutellum. With broad, strongly convex longitudinal swelling medially. Abdomen. Genitalia. Endosoma membranous without any sclerites; distal part of ductus seminis (dss) broad, caliciform with broad transparent portion dorsally, base of dss with broad sclerotized plate ( Figs 13a–c ). Left paramere C-shaped, apical process relatively broad, with large outgrowth baso-laterally, weakly arcuate and broadened in dorsal view ( Figs 13d, e ), sensory lobe moderately developed, weakly pointed ( Fig. 13d ). Right paramere with moderately long apical process and weakly developed sensory lobe ( Fig. 13f ).

Female. Like male in coloration, structure, texture, and vestiture. Genitalia. Bursa copulatrix ovoid ( Fig. 18b, c ); sclerotized rings large, occupying most of bursa copulatrix, kidney-shaped ( Figs 18b, c ); sclerotization of ventral labiate plate broad, nearly triangular ( Fig. 18d ).

Measurements. (♂ / ♀, *: holotype measurements): Body. Length: 6.10*/6.20–6.90, width 2.0*/2.20. Head. Length: 0.50*/0.56–0.60, width: 1.15*/1.16–1.20, interocular distance 0.40*/0.42. Antenna. Length of segment I: 0.66*/0.66–0.76, II: 2.95*/3.0, III: 3.95*/5.0, IV: 3.75*/4.5. Labium. Length of segment I: 0.9*/0.9, II: 0.87*/0.95, III: 1.0*/1.0, IV: 0.46*/0.46. Pronotum. Length 0.95*/1.0–1.05, width of anterior margin: 1.10*/1.20–1.30, length of lateral margin: 1.00*/1.00–1.05, width of posterior margin: 2.20*/2.30.

Etymology. The specific epithet refers to the type locality.

Biology. Unknown.

Distribution. Ecuador (Sucumbíos), Venezuela (Amazonas).

Remarks. Most like P. simplex in sharing the scutellum covered with long, erect setae ( Fig. 11l ). It can be distinguished by the presence of distinct lateral outgrowth of left paramere apical process ( Figs 13d, e ).
