Cylapinus minusculus Carvalho, 1986: 592, figs 10–13 (new species).
Cylapinus minusculus: Carvalho & Froeschner 1990: 319 (list); Schuh 1995: 21 (catalog); Gorczyca 2006a: 13 (catalog)
Diagnosis. Recognized by the following set of features: scutellum from entirely pale to dark castaneous with pale apex (Fig. 3a); corium with medial pale patch broad, bordering embolium and clavus (Fig. 3a); bursa copulatrix broader than wide, anterior margin weakly removed from first gonapophyses (Fig. 15f), sclerotized rings strongly curved, occupying almost entire lateral portion of bursa copulatrix (Fig. 15e, f); vlp without any sclerotization (Fig. 15d).
Redescription (composite description based on Carvalho 1986 and 18 additional specimens). Male. COLORATION (Fig. 3a, 7a). Head. Entirely dark castaneous to black, sometimes with pale patch on vertex; antennal segment I yellow, sometimes tinged with red; segment II varying from yellow with dark castaneous or dark brown apical two-thirds to entirely dark castaneous or dark brown; segments III and IV dark castaneous, basal one-fourth of segment III yellow; labium yellow, segment IV largely fuscous. Thorax. Pronotum. Dark castaneous to black. Mesoscutum and scutellum. Varying from entirely pale to dark castaneous with pale apex. Thoracic pleura. Varying from red or dark castaneous with yellow areas to entirely black; metathoracic scent gland evaporative area yellow. Hemelytron. Brown to dark brown with large, yellow areas; clavus brown to dark brown, sometimes with thin, yellow stripe along entire length; corium brown to dark brown with broad, yellow patch medially from clavus to embolium and cuneus varying from uniformly yellow to yellowish brown; membrane pale fuscous. Legs. Coxae yellow, sometimes weakly tinged with red; tibiae and femora yellow broadly tinged with red; tarsi varying from yellow to yellowish brown. Abdomen. Varying from yellow tinged with brown to entirely dark brown. TEXTURE AND VESTITURE. Vestiture as in generic description. Thorax. Thoracic pleura. Ventral surface of mesepimeron, anterior margin of metepisternum, posterior and ventral surface of metepisternum with characteristically perforated surface. STRUCTURE (Figs 3a, 7a, 11a–d). Thorax. Pronotum. Collar narrow, narrower than antennal segment I diameter; calli moderately developed, narrower than eye diameter. Abdomen. Anterior margin of abdominal segment I narrowly covered with perforated surface. Genitalia. Endosoma with well–developed, straight medial sclerite (Fig. 12a); secondary gonopore well differentiated (Fig. 12a); left paramere C-shaped, apical process when viewed laterally weakly curved, almost straight, somewhat widened subapically, narrowly tapering toward apex; paramere body in lateral view thin weakly tapering toward apex; sensory lobe well-developed, rounded (Fig. 12b); right paramere with apical process short, weakly narrowed toward apex when viewed laterally; sensory lobe prominent, rounded (Fig. 12c).
Female. Like male in coloration, structure, texture, and vestiture. Genitalia. Bursa copulatrix extending laterally beyond first gonapophysis, crescent-like (Fig. 15f); sclerotized rings paired, narrow, strongly arcuate (Figs 15f, e); spermathecal gland originating from area situated between lateral oviducts (Fig. 15f); ventral labiate plate without any sclerotization its surface weakly squamate (Fig. 15d); vestibulum without any sclerite (Fig. 20b); first valvula with ventral margin more or less arcuate, dorsal margin sinuate, strongly convex subapically (Fig. 21b); second valvula with ventral margin arcuate, dorsal margin weakly sinuate, strongly serrate; posterior wall of bursa copulatrix membranous.
