( Figures 2 View FIGURES 1 – 12 , 14 View FIGURES 13 – 22 , 28–33, 37 View FIGURES 23 – 32 View FIGURES 33 – 39 , 50 View FIGURE 50 , 90 View FIGURES 90 – 91 , Table 1)

Diagnosis. Recognized by the dark brown dorsum ( Fig. 2 View FIGURES 1 – 12 ), the antennal segment II stout, cylindrical, slightly narrowed basally, entirely covered with dense semirecumbent, relatively long setae, dark brown with contrastingly pale, white annulation at apical one third ( Fig. 2 View FIGURES 1 – 12 ), the vestiture on membrane distinctly developed, occupying entire surface outside the cells ( Fig. 90 View FIGURES 90 – 91 ), the endosoma with the LS strongly enlarged, occupying most of endosoma, broadened beneath base, and cylindrical at apical half ( Fig. 28 View FIGURES 23 – 32 ).

Most similar to C. cucullatus , C. funebris , C. pilosus , and C. plectipennis in sharing the hemelytron without any pale patches ( Figs. 3, 5, 9 View FIGURES 1 – 12 ). With C. cucullatus , C. pilosus , and C. plectipennis the present new species has at least two sclerites in the endosoma ( Figs. 40 View FIGURES 40 – 49 , 62, 67 View FIGURES 62 – 71 ). C. costaricaensis can, however, be distinguished by the stout antennal segment II with white annulation at apical one third ( Fig. 2 View FIGURES 1 – 12 ) and the shape of the male genitalia ( Figs. 28– 32 View FIGURES 23 – 32 ).

Description. Male. COLORATION ( Figs. 2 View FIGURES 1 – 12 , 14 View FIGURES 13 – 22 ). Dorsal surface entirely dark brown. Head. Dark reddish brown; antennal segments I and II dark brown except for contrastingly pale, white annulation at apical one third; segment III entirely blackish; segment IV blackish with broad, yellowish annulation near middle; labial segment I entirely castaneous; labial segment II castaneous at basal half, with broad, yellow annulation medially, remainder of segment II and entire segments III and IV brownish. Thorax. Thoracic pleura. Dark brown; scent gland efferent system blackish dark brown. Hemelytron. Membrane fuscous with brownish veins. Legs. Coxae dark brown with indistinct, dirty yellowish areas; trochanters dark brown; pro- and mesotibiae dirty yellowish, darkened, fuscous basally; tarsus brownish yellow. Abdomen. Dark brown, tinged with red. STRUCTURE, TEXTURE, AND VESTITURE ( Figs. 2 View FIGURES 1 – 12 , 14 View FIGURES 13 – 22 , 33, 37 View FIGURES 33 – 39 , 90 View FIGURES 90 – 91 ). Head. Somewhat rugose, covered with irregularly distributed setae; antennal segment I cylindrical, covered with moderately dense, semirecumbent setae; segment II stout, cylindrical, slightly narrowed basally, entirely covered with dense, semirecumbent, relatively long setae; labium long, reaching abdomen. Thorax. Pronotum. Covered with deep punctation. Mesoscutum and scutellum. Scutellum moderately convex, smooth. Hemelytron. Row of punctures on corium and clavus short, not reaching their half portions; membrane with area outside cells covered with dense, obvious setae.

Male genitalia. Aedeagus ( Fig. 28 View FIGURES 23 – 32 ). Endosoma strongly membranous; DSS cylindrical at basal two thirds, widened apically, its length longer than its width at base; LS strongly enlarged, occupying most of endosoma, broadened beneath base and cylindrical at apical half; MS small composed of two parts: thin, spindle like basal two thirds and small, ovoid apical one third. Right paramere ( Figs. 29–30 View FIGURES 23 – 32 ). Paramere body: inner margin weakly sinuate; apical process: lateral view: straight, moderately sharpened; dorsal view: elongate, left lateral margin moderately sinuate, extreme apex sharpened, medial process moderately developed, rounded. Left paramere ( Figs. 31–32 View FIGURES 23 – 32 ). Paramere body: thickened and relatively curved; apical process: lateral view: weakly curved, extreme apex blunt; dorsal view: dorsal margin weakly sinuate; extreme apex rounded; subapical incision relatively shallow; ventral margin distinctly curved.
