( Figs 1, 2 , 7–12 , 19–22, 27, 28 , 36 )

Holotype. Male. CAMEROON: Centre Province : Nkolbisson, 3.87115°N 11.45385°E, 29 Jan 1968, B. de Mire, ( AMNH _ PBI 00338446 ) ( MNHN).

Paratype: 1♀, CAMEROON: Centre Province : Nkolbisson, 3.87115°N 11.45385°E, 01 Feb 1968, B. de Mire, ( AMNH _ PBI 00338443 ) ( MNHN) .

Etymology: The species is named after Jocelia Grazia, who during a long and outstanding career at the Universidade Federal do Rio Grande do Sul, has made significant contributions to our knowledge of the Heteroptera in general and the Pentatomoidea in particular.

Diagnosis. The new species differs from C. virgula in the distinctly smaller body size, the color pattern of dorsum with V-shaped transverse stripe formed by reddish stripe along apical margin of corium, the uniformly whitish-yellow cuneus with narrowly reddish base and costal margin, the strongly reduced right paramere, the strongly sclerotized paddle-shaped appendage of vesica, and the very thin and basally tapering sclerotized rings of the dorsal labiate plate.

Description. Female. COLORATION ( Fig. 1 ): Dorsum whitish-yellow with red markings. Head: Pale yellow with reddish vertex; postocular area whitish yellow; frons orange, narrowly pale yellow along eye; antennal segment I pale yellow, segment II dark brown with pale yellow base, segments III and IV pale brown; eye dark brown with reddish tinge; labium whitish yellow with darkened apex of segment IV. Thorax: Pronotum with pale yellow collar, uniformly reddish area of calli and whitish yellow posterior part; thoracic pleura pale yellow, with reddish marking on metasternum; exposed part of mesonotum dirty orange with large reddish macula at middle; scutellum reddish. Legs: Pale yellow, fore coxa with reddish marking posteriorly, apical half of hind femur and basal third of hind tibia with reddish tinge. Hemelytron: Whitish yellow, clavus with indistinct small and diffuse pale dark brown spot in basal third and narrowly reddish brown inner margin; corium with narrowly reddish costal margin and large transverse red spot along apical margin; cuneus with narrowly reddish base and costal margin; membrane translucent, pale brown, with reddish outer cell vein. Abdomen: Pale yellow, with interrupted reddish line at sides.

STRUCTURE: Body 4.3 × as long as width of pronotum; total length 3.1; vertex 1.6 × as wide as eye, 1.2 × as wide as length of antennal segment I; segment II 1.6 × as long as basal width of pronotum, 1.9 × as long as width of head; pronotum twice as long as antennal segment I, 1.5 × as wide as long.

GENITALIA: Sclerotized rings of dorsal labiate plate thin, very weakly sclerotized, long and narrow, basally tapering ( Fig. 36 ).

Male. COLORATION ( Fig. 2 ): Similar to male except as follows: frons entirely pale yellow; antennal segment II brown with pale yellow base, segment III brown; macula on exposed part of mesonotum dark brown with reddish edging; scutellum brown with reddish tinge; fore coxa uniformly pale yellow; small spot in basal third of clavus better expressed, dark brown and transverse; abdomen pale yellow, with somewhat darker genital segment.

STRUCTURE: Body 3.8 × as long as width of pronotum; total length 3.0; vertex 1.6 × as wide as eye, 1.1 × as wide as length of antennal segment I; segment II 1.5 × as long as basal width of pronotum, 1.9 × as long as width of head; pronotum twice as long as antennal segment I, 1.6 × as wide as long.

GENITALIA: Right paramere reduced, narrow, bent at middle, with hook-shaped apex; left paramere twice as long as right one, with upturned, hook-shaped apex ( Figs. 19–22 ). Vesica with large, paddle-shaped, apically expanded and flattened, finely serrated sclerite ( Figs. 27, 28 ).
