Cicatrices of pronotum with light brown punctures delimiting anterior sulci (Fig. 19A). Scutellum with anterior margin yellow (Fig. 19A). Body ventrally with narrow brown stripes (Fig. 19B). Male genitalia (Fig. 7A–D). Pygophore remarkably excavated laterally (Fig. 7C–D), leaving the parameres visible in lateral view. Dorsal rim rugose and projected posteriorly, surpassing level of posterolateral angles (Fig. 7A). Superior process of genital cup triangular, short, tapering to the base, and close to dorsal rim; visible in dorsal view (Fig. 7A–C).

Valvifers 8 subtrapezoidal, posterior margin sinuous; inner angles reaching basal third of valvifers 9, not touching each other; inner margins forming a long and narrow drop-like excavation. Valvulae 9 exposed. Comments. The H. excavatus like H. omegoides, (Fig. 10C–D) and H. boerneri (Nunes et al. 2020, Fig. 2C) has the lateroventral side of the pygophore remarkably excavated, leaving paramere completely exposed laterally (Fig. 7C–D). This condition also gives the impression that ventral rim of the pygophore is strikingly projected caudally, completely different from all other species of the genus. The species H. excavatus and H. omegoides show the lateral margins of the posterior face of the proctiger ventrally projected (Figs. 7B, 10B) (just surpassing the margin in H. excavatus and strongly developed in H. omegoides). Females from H. excavatus and H. boerneri are very similar (Fig. 7E; Nunes et al. 2020, Fig. 2D). The main difference between these species is the median excavation of valvifers 8 in H. excavatus (Fig. 7E) that is narrower with apices of inner angles closer to each other than in H. boerneri. Etymology. The name refers to the strongly excavated lateral surface of the pygophore. Distribution (Fig. 21B). BRAZIL: Rondônia, Mato Grosso.

This species is related to H. trabeculus and H. similis by the paramere golf club like; posterior face of proctiger pentagonal; dorsal rim medially with a small convex expansion, and expansions of ventral rim with setae long and dense on apex (Figs. 11A–D, 14A–D; Nunes et al. 2020, Fig. 8A–C). However, in H. pentagonalis the posterior process of the paramere is curved dorsolaterally (straight in H. similis and H. trabeculus). The superior process of genital cup is curved with a distal digitiform process on ventral margin (straight in H. trabeculus and curved but without ventral process in H. similis). The valvifers 8 of these species are very similar, especially the mesial distal excavation V-shaped, but the outer angles of distal margin are more angulated in H. pentagonalis than in the other species. Etymology. Name refers to the pentagonal form of the posterior face of the proctiger. Distribution (Fig. 21B). BRAZIL: Maranhão, Pará.

Cicatrices of pronotum with light brown punctures delimiting anterior sulci (Fig. 19A). Scutellum with anterior margin yellow (Fig. 19A). Body ventrally with narrow brown stripes (Fig. 19B). Male genitalia (Fig. 7A–D). Pygophore remarkably excavated laterally (Fig. 7C–D), leaving the parameres visible in lateral view. Dorsal rim rugose and projected posteriorly, surpassing level of posterolateral angles (Fig. 7A). Superior process of genital cup triangular, short, tapering to the base, and close to dorsal rim; visible in dorsal view (Fig. 7A–C). Paramere spatulate; anterior lobe developed and rounded; posterior lobe well-developed and subtriangular; outer margin black; stalk with inner medial carina low, evanescent and curved toward anterior lobe (Fig. 7B–C). Proctiger with dorsolateral tufts of setae clearly separated by medial bridge; posterior face pentagonal with both lateral margins swollen and somewhat ventrally projected (Fig. 7B–C). Ventral rim remarkably projected caudally; medial excavation shallow; expansions slightly tumid, acuminated, and narrow; apices densely setose, surpassing level of posterolateral angles in ventral view (Fig. 7D). Female genitalia (Fig. 7E). Plates with long and sparse setae. Valvifers 8 subtrapezoidal, posterior margin sinuous; inner angles reaching basal third of valvifers 9, not touching each other; inner margins forming a long and narrow drop-like excavation. Valvulae 9 exposed. Comments. The H. excavatus like H. omegoides, (Fig. 10C–D) and H. boerneri (Nunes et al. 2020, Fig. 2C) has the lateroventral side of the pygophore remarkably excavated, leaving paramere completely exposed laterally (Fig. 7C–D). This condition also gives the impression that ventral rim of the pygophore is strikingly projected caudally, completely different from all other species of the genus. The species H. excavatus and H. omegoides show the lateral margins of the posterior face of the proctiger ventrally projected (Figs. 7B, 10B) (just surpassing the margin in H. excavatus and strongly developed in H. omegoides). Females from H. excavatus and H. boerneri are very similar (Fig. 7E; Nunes et al. 2020, Fig. 2D). The main difference between these species is the median excavation of valvifers 8 in H. excavatus (Fig. 7E) that is narrower with apices of inner angles closer to each other than in H. boerneri. Etymology. The name refers to the strongly excavated lateral surface of the pygophore. Distribution (Fig. 21B).

Valvulae 9 exposed. Valvifers 9 strongly setose. Comments. This species is related to H. trabeculus and H. similis by the paramere golf club like; posterior face of proctiger pentagonal; dorsal rim medially with a small convex expansion, and expansions of ventral rim with setae long and dense on apex (Figs. 11A–D, 14A–D; Nunes et al. 2020, Fig. 8A–C). However, in H. pentagonalis the posterior process of the paramere is curved dorsolaterally (straight in H. similis and H. trabeculus). The superior process of genital cup is curved with a distal digitiform process on ventral margin (straight in H. trabeculus and curved but without ventral process in H. similis). The valvifers 8 of these species are very similar, especially the mesial distal excavation V-shaped, but the outer angles of distal margin are more angulated in H. pentagonalis than in the other species. Etymology. Name refers to the pentagonal form of the posterior face of the proctiger. Distribution (Fig. 21B).

Etymology: The species is named in honor of Dr. Joc��lia 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 Jos�� Fernandes in Porto Alegre, Morro do Osso, (see above) were collected on Pyrostegia venusta (Ker Gawl.) Miers, a Bignoniaceae.
