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 .
