Recognized by the following set of characters: antennal segment II in both sexes thinner than segment I ( Figs 50, 51 ); pronotum with yellow, longitudinal stripe medially and with two yellow patches, each situated laterally, bordering callus ( Figs 50, 51 ); scutellum with three patches: two basolaterally and one apically ( Figs 50, 51 ); R+M vein yellow, narrowly black medially ( Figs 50, 51 ); corium with broad patch medially ( Figs 50, 51 ); endosomal sclerite arcuate ( Fig. 115 ); left paramere with sensory lobe moderately developed ( Figs 116, 117 ). Most similar to C. stellatus and C. tenuicornis in sharing scutellum with three patches ( Figs 48–53 ). It can, however, be easily distinguished by the coloration of the hemelytron and the shape of the male genitalia. Redescription. Male. Coloration ( Figs 50, 51 , 63 ). Dorsum dark brown black with large yellow and dirty yellow areas. Head. Vertex dirty yellow, broadly tinged with brown to dark brown; frons, clypeus, and mandibular plate dark brown to black; frons tinged with yellow basally; maxillary plate, buccula, and gula yellow; antenna dark brown; segment II contrastingly yellow apically; labium dark brown. Thorax . Pronotum dark brown with large, yellow areas; collar yellow; calli dirty yellow, tinged with brown or fuscous; anterolateral portion with more or less developed yellow patch, sometimes reaching posterior margin; medial portion with yellow, longitudinal stripe from posterior margin of pronotal calli till posterior margin; posterior margin tinged with yellow along entire length. Mesoscutum and scutellum brown to dark brown; scutellum with three large, yellow or reddish yellow patches: two basolaterally and one apically. Thoracic pleura. Proepimeron and proepisternum varying from entirely dark brown to dark brown, broadly tinged with yellow; remaining pleura dark castaneous; evaporative areas and peritreme contrastingly yellow. Hemelytron. Corium dark brown black with basal half slightly paler than apical half; medial fracture yellow medially; R+M vein yellow, interrupted medially; medial portion of corium with relatively broad, yellow patch; apical outer angle of corium yellow; inner margin of corium yellow; clavus dark brown, claval vein yellow along entire length; clavus dark brown, its inner angle broadly yellow; membrane fuscous. Legs. Coxae dark castaneous; pro- and mesocoxae yellow at apical one fourth; metacoxa yellow at apical half; remaining segments of all legs dark brown with dirty yellow and yellow areas. Abdomen black, tinged with yellow laterodorsally and subapically. Structure, texture and vestiture ( Figs 50, 51 , 63 , 107–109 ). Body elongate; dorsum covered with short, fine, semirecumbent setae. Head. Antennal segment II thinner than segment I. Scutellum moderately convex. Male genitalia ( Figs 115–119 ). Aedeagus ( Fig. 115 ). Endosoma strongly membranous, with one, strongly arcuate sclerite. Left paramere ( Figs 116–118 ). Apical process thin, arcuate; paramere body well arcuate in dorsal and lateral views; sensory lobe moderately developed in dorsal view. Right paramere ( Fig. 119 ). Apical process short, sharply pointed; paramere body with apical two thirds with dextrolateral margin weakly arcuate and sinistrolateral margin weakly sinuate; basal one third with both margins arcuate; sensory lobe moderately developed; basal process weakly tapering.
