( Figs 6b , 11m –o , 14f–k )

Cylapus (Peltidocylapus) scutellaris Poppius, 1909: 12 , 43 (sp. nov.).

Cylapus (Peltidocylapus) scutellaris: Bergroth 1920: 71 (list); Carvalho 1957: 31 (list).

Peltidocylapus scutellaris: Carvalho & Fontes 1968: 276 (list); Schuh 1995: 32 (catalog), 2002–2013 (online catalog); Gorczyca 2006a: 19: fig. 3 (catalog).

Diagnosis. Recognized by the following combination of characters: antennal segment II with relatively broad, apical, white annulation width equal to half of interocular distance ( Fig. 6b ; Gorczyca 2006a: fig. 3); posterior lobe of pronotum with moderately developed swelling medially ( Fig. 6b , 11m ; Gorczyca 2006a: fig. 3); scutellum convex, with strongly developed, longitudinal medial swelling ( Fig. 6b , 11m ; Gorczyca 2006a: fig. 3); clavus with short, yellow stripe subapically ( Fig. 6b ; Gorczyca 2006a: fig. 3); endosoma membranous ( Figs 14f–k ); distal sclerotized portion of ductus seminis (dss) short, rectangular ( Figs 14f ); ventro–apical margin of ductus seminis inside endosoma with shallow incision ( Fig. 14h ); left paramere apical process with short outgrowth baso-dorsally ( Figs 14i, j ).

Redescription. Male. COLORATION ( Fig. 6b ; Gorczyca 2006a: fig. 3). Dorsum varying from dark castaneous to dark brown. Head. Dark brown, tinged with yellow; antennal segment I dark castaneous; antennal segment II with relatively broad, apical, white annulation that is as wide as half of interocular distance; segments II–IV dark brown; labium dark castaneous. Thorax. Pronotum. Varying from dark castaneous to dark brown. Mesoscutum and scutellum. Varying from dark castaneous to dark brown with large, indistinct, dark yellow tinge baso-laterally. Thoracic pleura. Dark castaneous with dark yellow areas; metathoracic scent gland evaporative areas mostly fuscous, tinged with yellow posteriorly. Hemelytron. Dark castaneous to dark brown; clavus with short, yellow stripe subapically, bordering claval suture; membrane dark grey, weakly tinged with yellow medially. Legs. Procoxa dark castaneous narrowly tinged with yellow apically; meso- and metacoxae yellow tinged with dark brown basally; femora dark castaneous with pale yellow annulation subapically; meso- and metafemora with pale yellow annulation basally; tibiae and tarsi dark stramineous with dark brown areas. Abdomen. Dark castaneous. TEXTURE AND VESTITURE ( Figs 6b , 11m ). Thorax. Scutellum. Covered with two types of setae: one short, fine, recumbent, and other longer, covering medial swelling. Hemelytron. Covered with short, fine, semi-recumbent setae. STRUCTURE ( Fig. 6b , 11m ; Gorczyca 2006a: fig. 3). Thorax. Pronotum. Posterior lobe with moderately developed swelling medially. Scutellum. With strongly convex, broad longitudinal medial swelling. Abdomen. Genitalia. endosoma membranous ( Figs 14f–k ); distal sclerotized portion of ductus seminis (dss) short, rectangular, its dorsal portion weakly sclerotized, transparent ( Figs 14f ); ventro-apical margin of ductus seminis inside endosoma with shallow incision ( Fig. 14h ); left paramere apical process with short outgrowth baso-dorsally ( Figs 14i, j ); right paramere sickle-shaped ( Figs 14k ).
