Cylapinus Carvalho

Cylapinus Carvalho, 1986: 592 (new genus). Type species: Cylapinus minusculus Carvalho, 1986 (original designation). Cylapinus: Carvalho & Froeschner 1990: 311 (list); Schuh 1995: 21 (catalog), 2002–2013 (online catalog); Gorczyca 2000: 48, 2006a: 13 (catalog); Wolski 2017: 405, fig. 28 (key to genera)

Diagnosis. Easily recognized from other Cylapini by the following characters: dorsum shiny ( Figs 3a, b ); head shiny ( Figs 7a , 8a ); vertex with shallow longitudinal sulcus along midline ( Figs 8a , 11a ); eyes moderately pedunculate ( Fig. 8a ); clypeal base weakly removed from ventral margin of eyes ( Fig. 8a ); antennal insertion weakly removed from suture between maxillary and mandibular plates antenna relatively short, shorter than body length ( Fig. 8a ); pronotum with posterior margin straight or weakly arcuate, covering mesoscutum ( Figs 3a, b ); metathoracic scent gland evaporative areas narrow, restricted to ventral margin of metepisternum, peritreme moderately raised above evaporative areas ( Fig. 11c ); scutellum short, ca 0.8 x shorter than pronotum; endosoma simple, with a single sclerite ( Figs 3a, b ).

Redescription. Male. COLORATION ( Figs 3a, b , 7a ). Thorax. Pronotum. Dark castaneous to black. Hemelytron. Brown to dark brown with yellow areas; corium with developed yellow patch medially; cuneus with developed, yellow, or white patch basally. SURFACE AND VESTITURE ( Figs 3a, b 7a , 8a , 11a–d ). Dorsum covered with long, erect setae. Head. Head strongly shining, covered with sparse, erect, and semi-recumbent setae; antennal segment I shiny, covered with sparse, thick, erect setae; segment II shiny, covered with sparse erect and semi-recumbent setae on basal half and denser, semi-recumbent setae on apical half; segments III and IV covered with relatively long, semi-recumbent setae. Thorax. Pronotum. Shiny, with deep, large punctures, covered with long erect setae. Thoracic pleura. Shiny, covered with sparse, erect, long setae; proepimeron with broad, deep, and moderately dense punctation; remaining pleura impunctate. Mesoscutum and scutellum. Punctate, covered with long, erect setae. Hemelytron. Covered with semi-recumbent and erect setae; corium and clavus densely punctate. Abdomen. Covered with fine, long, erect, and semi-recumbent setae. STRUCTURE ( Figs 3a, b 7a , 8a , 11a–d ). Macropterous. Body elongate oval. Head. Eyes moderately pedunculate; vertex with shallow, longitudinal sulcus medially; clypeus short, weakly convex, base weakly removed from ventral margin of eye; antennal insertion weakly removed from suture between maxillary and mandibular plates; antennal segment I short, as long as or weakly longer than interocular distance; antennal segment II cylindrical; antennal segments III and IV filiform. Thorax. Pronotum. Trapeziform; posterior margin straight or weakly arcuate. Mesoscutum and scutellum. Mesoscutum weakly exposed or entirely obscured by posterior part of pronotum; scutellum flattened or weakly convex, small, ca 0.8 x shorter than pronotum. Thoracic pleura. Metathoracic scent gland evaporative areas weakly developed, occupying ventral margin of metepisternum; peritreme moderately raised above evaporative areas, positioned anteriorly on metepisternum. Legs. Tarsus with tarsomere I shorter than length of II and III tarsomeres combined; pretarsal claw with subapical tooth. Abdomen. Genitalia. Aedeagus with theca weakly sclerotized; ductus seminis thin and short; endosoma simple, with indistinct longitudinal, medial sclerotization medially ( Figs 12a, d ). Left paramere sickle shaped, apical process in lateral view ovoid, narrow apically or broadened basally, strongly narrowed toward apex, sensory lobe well-developed, rounded ( Figs 12b, e ). Right paramere C-shaped, most often with well-developed sensory lobe ( Figs 12c, f ).

Female. Like male in coloration, structure, texture, and vestiture. For female genitalia see description of C. minusculus .
