 Diagnosis. Recognized by the following set of characters: antennal segment II thinner than segment I (Figs 40–42); pronotum black except for yellow patch on humeral angle (Figs 40–42); corium with yellow, large, oblique patch medially (Figs 40–42); 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).   
 Most similar to C. ruficeps in sharing large, oblique patch medially (Figs 40–42, 46, 47). It can, however, be distinguished by the head coloration and the shape of the male genitalia (Figs 80–84).   
  Redescription. Male  (composite description based on BERGROTH 1922 and the specimens mentioned below). Coloration (Figs 40–42, 58). 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, 58, 78, 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). Aedeagus (Fig. 80). 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). Apical process sinuate; paramere body thin, with distinct sensory lobe. Right paramere (Fig. 84). Sinuate; apical process short, obtuse; sensory lobe well developed.   
 Female. Similar to male in structure, texture, and vestiture.
