Diagnosis. Recognized by the following set of characters: antennal segment II in males thicker than segment I ( Fig. 36 View Figs 36–40 ); pronotum entirely black except for small, white patches on humeral angle ( Fig. 36 View Figs 36–40 ); hemelytron entirely black except for tiny patch on apex of clavus ( Fig. 36 View Figs 36–40 ); endosoma with four sclerites: es1 short, cylindrical, relatively thin, without denticles at basal two thirds, apical one third globular, serrate, relatively broad; es2 long, cylindrical at basal two thirds, without denticle, weakly broadened at apical one third; es3 strongly tapering toward apex, sharply pointed, basal half without denticles, apical half serrate; es4 arcuate, sharply pointed, without denticles at basal half, serrate at apical half ( Fig. 66 View Figs 66–75 ); left paramere when viewed dorsally with sensory lobe distinctly developed ( Fig. 67 View Figs 66–75 ).

Most similar to C. antennatus , C. luridus , C. marginicollis , and C. tucuruiensis in sharing the tuberculate antennal segment II thicker than segment I in males ( Figs 36, 38 View Figs 36–40 , 43, 55, 56, 57, 59, 60 View Figs 56–65 , 92). It can, however, be distinguished by the almost entirely black pronotum (red laterally in abovementioned species) ( Fig. 36 View Figs 36–40 ) and the shape of the male genitalia ( Figs 66, 70 View Figs 66–75 ). With C. antennatus , C. luridus , C. marginicollis , C. ruficeps , C. stellatus , and C. tenuicornis it shares the endosomal sclerites es1 and e2 broadened and serrate apically ( Figs 71 View Figs 66–75 , 85 View Figs 80–89 , 97, 102 View Figs 97–106 , 110 View Figs 110–119 , 135 View Figs 135–144 ) but can be distinguished by the es3 that is strongly tapering ( Fig. 66 View Figs 66–75 ). Redescription. Male (composite description based on CARVALHO 1989 and the specimens mentioned above). Coloration ( Figs 36 View Figs 36–40 , 56 View Figs 56–65 ). Dorsum castaneous to black, with weakly developed dirty yellow areas. Head black; basal portion of frons, maxillary plate, and buccula tinged with yellow; gula yellow; antenna varying from castaneous red to black; labium black. Thorax. Pronotum black; collar yellow; humeral angle narrowly dirty yellow. Mesoscutum and scutellum black; scutellum narrowly dirty yellow apically. Thoracic pleura black; metathoracic scent gland evaporative area yellow, tinged with fuscous. Hemelytron castaneous to black; apical margin of corium and basal margin of cuneus contrastingly yellow; membrane fuscous. Legs. Coxae and femora black; tibiae and tarsi dark brown. Abdomen black, tinged with dirty yellow ventrally. Structure, texture and vestiture ( Figs 36 View Figs 36–40 , 56 View Figs 56–65 ). Dorsum covered with relatively long, semirecumbent and erect setae. Head. Antennal segment II thicker than segment I, gradually becoming narrower toward apex, tuberculate. Thorax. Pronotum. Calli moderately developed. Scutellum moderately convex. Male genitalia ( Figs 66–70 View Figs 66–75 ). Aedeagus ( Fig. 66 View Figs 66–75 ). Endosoma with four sclerites (es1–es4): es1 short, cylindrical, relatively thin, without denticles at basal two thirds, apical one third globular, serrate, relatively broad; es2 long, cylindrical at basal two thirds, without denticle, weakly broadened at apical one third; es3 strongly tapering toward apex, sharply pointed, basal half without denticles, apical half serrate; es4 arcuate, sharply pointed, without denticles at basal half, serrate at apical half. Left paramere ( Figs 67–69 View Figs 66–75 ). Paramere body arcuate; sensory lobe distinctly developed. Right paramere ( Fig. 70 View Figs 66–75 ). Apical process sharply pointed; paramere body with inner margin weakly sinuate, outer margin arcuate; sensory lobe moderately developed.

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

Measurements (in mm). J / ♀ (*: holotype measurements, taken from CARVALHO 1989). Body. Length: 6.40–6.50 / 6.00*–6.60, width 2.10–2.40 / 2.00*–2.10. Head. Length: 0.60 / 0.40*–0.50, width: 1.20–1.34 / 1.20*–1.30, interocular distance 0.50–0.58 / 0.48*–0.55. Antenna. Length of segment I: 0.90 / 0.90*–1.10, II: 5.20 / 3.70–4.10, III: 4.00 / 3.25–3.60*, IV: 4.60 / 2.20*. Labium. Length of segment I: 0.60 / 0.75–0.78, II: 0.90 / 0.88–0.92, III: 0.70 / 1.12–1.20, IV: 0.30 / 0.50. Pronotum. Length: 1.90–2.15 / 0.80*–1.10, width of anterior margin: 1.10 / 1.15, length of lateral margin: 0.90–1.10, width of posterior margin: 1.90–2.15 / 1.80–2.10*.

CARVALHO (1989) gave length of antennal segment II of the holotype as 1.0 mm, apparently by mistake.

Biology. Collected using insecticidal logging of mostly bare green leaves, some with covering of lichenous or bryophitic plants in terre firme forest.

Distribution. Bolivia (Cochabamba) (this paper), Brazil (Pará) ( CARVALHO 1989), Ecuador (Orellana) (this paper).
