Diagnosis. Recognized by the following set of characters: antennal segment II thinner than segment I ( Figs 40–42 View Figs 36–40 ); pronotum black except for yellow patch on humeral angle ( Figs 40–42 View Figs 36–40 ); corium with yellow, large, oblique patch medially ( Figs 40–42 View Figs 36–40 ); endosomal sclerite es1 long, with basal two thirds tapering toward apex, apical one third broadened, extreme apex serrate; es2 short, broad, cylindrical, tapering toward apex at apical one sixth; es3 long, strongly tapering toward apex, sharply pointed; es4 long, weakly arcuate, slightly tapering toward apex, sharply pointed ( Fig. 80 View Figs 80–89 ).

Most similar to C. ruficeps in sharing large, oblique patch medially ( Figs 40–42, 46, 47 View Figs 36–40 ). It can, however, be distinguished by the head coloration and the shape of the male genitalia ( Figs 80–84 View Figs 80–89 ).

Redescription. Male (composite description based on BERGROTH 1922 and the specimens mentioned below). Coloration ( Figs 40–42 View Figs 36–40 , 58 View Figs 56–65 ). Dorsum black with yellow areas. Head. Vertex and basal portion of frons varying from yellow to brown; rest of head, except of yellow gula and posterior portion of maxillary plates and buccula black; antenna dark castaneous to black; segment III with narrow, yellow annulation basally; labium black. Thorax. Pronotum black, except for yellow humeral angle. Mesoscutum and scutellum black; scutellum yellow apically. Thoracic pleura black; mesepimeron with yellow stripe along entire length; metathoracic scent gland evaporative areas fuscous yellow. Hemelytron black to dark brown with yellow areas; basal portion of R+M vein yellow; corium with short, relatively broad, oblique yellow patch medially; inner margin of corium and outer margin of clavus narrowly yellow along entire length; apex of clavus narrowly yellow; apex of embolium and basal margin of cuneus yellow; membrane fuscous. Legs. Coxae black; metacoxa yellow at apical half; remaining segments varying from brown dirty yellow to black. Abdomen black. Structure, texture and vestiture ( Figs 40–42 View Figs 36–40 , 58 View Figs 56–65 , 78, 79 View Figs 76–79 ). Head covered with relatively long, erect, sparse setae; antenna covered with short, sparse, erect and semirecumbent setae; segment I thin, weakly broadened toward apex; segment II thinner than segment I, cylindrical. Thorax. Pronotum covered with relatively long, erect setae; calli moderately developed. Mesoscutum and scutellum covered with relatively long, erect, moderately dense setae; scutellum weakly convex. Male genitalia ( Figs 80–84 View Figs 80–89 ). Aedeagus ( Fig. 80 View Figs 80–89 ). Endosoma with four sclerites (es1–es4): es1 long, with basal two thirds tapering toward apex, apical one third broadened, extreme apex serrate; es2 short, broad, cylindrical, tapering toward apex at apical one sixth; es3 long, strongly tapering toward apex, sharply pointed; es4 long, weakly arcuate, slightly tapering toward apex, sharply pointed. Left paramere ( Figs 81–83 View Figs 80–89 ). Apical process sinuate; paramere body thin, with distinct sensory lobe. Right paramere ( Fig. 84 View Figs 80–89 ). Sinuate; apical process short, obtuse; sensory lobe well developed.

Female. Similar to male in structure, texture, and vestiture.
