Diagnosis. Recognized by the following set of characters: antennal segment II in males thicker than segment I ( Figs 38 , 57 , 76 ); lateral portion of pronotum broadly tinged with red ( Figs 37–39 , 57 ); hemelytron entirely fuscous with indistinct patch on apex of clavus ( Figs 37–39 ); endosoma with four sclerites (es1–es4): sclerites es1 and es3 clublike and serrate at broadened parts; es1 with basal one third about four times thinner than apical two thirds; es3 with basal half about two times thinner that apical half; es2 ellipsoid, entirely serrate; es4 arcuate, sharply pointed ( Fig. 71 ).

Most similar to C. amazonicus , C. luridus , C. marginicollis , and C. tucuruiensis in sharing segment II in males thicker than segment I ( Figs 36, 38 , 43, 55, 56, 57, 59, 60 , 92). It can, however, be distinguished by the shape of the male genitalia ( Figs 66–75 , 85–89 , 97–101 , 110–114 , 140–144 ).

Redescription. Male. Coloration ( Figs 37–39 , 57 ). Black with red and yellow areas. Head mostly black with brown and dirty yellow areas; vertex dark brown with dirty yellow stripe along internal margin of eye; antenna varying from dark castaneous to black; segment III with broad, yellowish annulation basally; labium varying from dark brown to black. Thorax. Pronotum black, broadly tinged with red laterally; humeral angle narrowly tinged with yellow. Mesoscutum and scutellum black, narrowly yellow apically. Thoracic pleura. Proepisternum black; proepimeron narrowly black anteriorly and ventrally, rest of proepimeron red; mesepimeron with yellow stripe along posterior margin; metathoracic scent gland evaporative areas yellow, broadly tinged with fuscous. Hemelytron black; clavus with narrow patch apically; apical margin of corium and basal margin of cuneus yellow; membrane dark fuscous. Legs. Coxae dark castaneous to black; remaining segments dark brown black. Structure, texture and vestiture ( Figs 37–39 , 57 , 76–77 ). Dorsum covered with relatively long, semirecumbent and erect setae. Head. Antennal segment II thicker than segment I, gradually becoming narrower toward apex. Thorax. Pronotum. Calli moderately developed. Scutellum moderately convex. Male genitalia ( Figs 71–75 ). Aedeagus ( Fig. 71 ). Endosoma with four sclerites (es1–es4): sclerites es1 and es3 clublike and serrate at broadened parts; es1 with basal one third about four times thinner than apical two thirds; es3 with basal half about two times thinner than apical half; es2 ellipsoid, entirely serrate; es4 arcuate, sharply pointed. Left paramere ( Figs 72–74 ). Apical process arcuate; paramere body with inner margin arcuate and outer margin sinuate; sensory lobe strongly developed. Right paramere ( Fig. 75 ). Apical process short, obtuse; paramere body with inner and outer margins sinuate; sensory lobe moderately developed; basal process short.

Female. Similar to male in coloration, structure, texture, and vestiture. Head. Antennal segment II thinner than segment I, weakly broadened apically.
