Etymology: The species is named in honor of Dr. Jocélia Grazia, for her immense and valuable contribution to the knowledge of Neotropical Pentatomidae .

Diagnosis: Dorsal surface green, variegated with yellow spots. Humeral angles poorly developed, apices rounded and black ( Fig. 38 ). Scutellum long, apex reaching apices of coria ( Fig. 38 ). Ventral surface variegated in yellow and brown, densely and uniformly punctate ( Fig. 39 ). Peritreme short. Metasternal process in lateral view more elevated anteriorly than posteriorly ( Fig. 25 ); punctate, with punctures dark and deep. Superior process of genital cup rectangular ( Fig. 27 ). Head of the paramere with posterior lobe bifid ( Fig. 27 ).

Description. Head: Antennae yellow ( Figs 38–39 ); antennomere IV subequal in length to V.

Thorax: Pronotum densely and irregularly punctate ( Fig. 38 ). Coria maculate. Ventrally with dark irregular spots; punctures concolorous or dark and large. Propleuron punctate. Evaporatorium dark brown ( Fig. 39 ). Peritreme reaching half of the distance from ostiole to the lateral margin of the metapleuron ( Fig. 39 ). Metasternal process, bifurcation receiving fourth rostral segment ( Figs 24–25 ). Yellow legs with dark macules on femur ( Fig. 39 ).

Abdomen: Each connexival segment with two dark small spots on the lateral margins ( Fig. 38 ). Punctures dark and large ventrally ( Fig. 39 ).

Male genitalia: Pygophore rectangular ( Figs 26, 28 ). Posterolateral angles slightly developed ( Figs 26, 28 ), sparsely punctate. Ventral rim with expansions tumid and strongly projected, surpassing apices of posterolateral angles in ventral view ( Fig. 28 ). Ventral surface with tumid central area strongly projected posteriorly, reaching beyond the bottom of the excavation of the ventral rim ( Figs 26, 28 ). Phallus with ventral face wrinkled; vesica elongate and curved ( Fig. 29 ).

Female genitalia: Gonocoxites 8 with distal margins straight or slightly arcuate; inner margins contiguous ( Fig. 30 ). Pars intermedialis cylindrical. Capsula seminalis with three slim projections about the same length; one of them with secondary projections ( Fig. 31 ).

Measurements: Total length: 11.9–14.7; head length: 1.3–1.8; head width: 2.5–2.7; pronotum length: 2.5–3.3; pronotum width: 7.8–9.7; humeral angles length: 0.4–0.9; humeral angles width: 0.5–0.8 abdominal width: 7.6–9.6; length of antennomeres: I: 0.5–0.9; II: 0.7–1.1; III: 1.1–1.9; IV: 1.6–2.5; V: 1.5–2.6.

Comments: Edessa graziae sp. nov. can be identified by the small yellow marks on the dorsal variegated surface. Also, the humeral angles are less projected than in the other species. This new species is clearly allied to E. sahlbergii (see comments of E. sahlbergii ).

Bionomics: All specimens collected by José Fernandes in Porto Alegre, Morro do Osso, (see above) were collected on Pyrostegia venusta (Ker Gawl.) Miers , a Bignoniaceae .

Distribution ( Fig. 40 ): BRAZIL: Minas Gerais, Santa Catarina, Rio Grande do Sul; ARGENTINA: Catamarca, Cordoba, Entre Rios.
