Cylapoides unicolor Carvalho, 1952

Cylapoides unicolor Carvalho, 1952a: 271 , fig. 10 (new species).

Cylapoides unicolor: Carvalho 1957: 29 (catalog); Carvalho & Froeschner 1987: 154 (list); Schuh, 1995: 23 (catalog); Gorczyca 2006a: 14 (catalog).

Diagnosis. Recognized by the following set of features: dorsum entirely dark brown ( Fig. 3d ); antennal segment II varying from yellow with dark brown apex to dark brown with two annulations ( Fig. 3d ); endosoma composed of more or less developed sclerotized lobes ( Fig. 12g ); left paramere T-shaped, apical process perpendicular to paramere body, thin weakly tapering toward apex ( Fig. 12h ); bursa copulatrix rounded; dlp small, restricted to the anterior portion of bursa copulatrix, sclerotized rings ovoid, small ( Fig. 15g ).

Redescription (composite description based on Carvalho 1952a and 16 additional specimens). Female. COLORATION ( Fig. 3d ). Head. Entirely dark brown; antennal segment I dark brown, pale yellow at basal one third; segment II varying from yellow with dark brown apex to dark brown with two annulations – one, broader medially and other, narrower apically; segments III and IV dark brown; segment III narrowly yellow basally; labium dark brown. Pronotum, mesoscutum and scutellum. Dark brown with silvery tinges. Thoracic pleura. Dark brown. Hemelytron. Varying from dark red to dark brown, basal one third with irregular, silvery stripes; apex of exocorium with small, yellow patch; membrane fuscous, venation yellow. Legs. Dark brown; tibiae with broad yellow annulation near apex. TEXTURE AND VESTITURE. As in generic description. STRUCTURE. Thorax. Pronotum. Posterior margin strongly convex medially ( Fig. 11e ). Abdomen. Genitalia. Bursa copulatrix rounded; dlp small, restricted to the anterior portion of bursa copulatrix, sclerotized rings ovoid, small; posterior lobe of bursa copulatrix membranous ( Fig. 15g ).

Male. Like female in coloration, structure, texture, and vestiture. Abdomen. Genitalia. Theca weakly sclerotized; ductus seminis moderately thick and long; endosoma composed of developed sclerotized lobes ( Fig. 12g ); left paramere T-shaped; apical process perpendicular to paramere body, thin weakly tapering toward apex ( Fig. 12h ).
