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
.
