Diagnosis: Dorsal surface green, variegated with dark spots (Fig. 36), spots associated or not with punctuation. Humeral angles with apices slightly acuminate, concolorous with its surface, punctate (Fig. 36). Scutellum long, apex reaching apices of corium (Fig. 36). Ventral surface yellow with dark brown spots, densely and uniformly punctate (Fig. 37). Peritreme short. Metasternal process in lateral view more elevated anteriorly than posteriorly (Fig. 17) and punctate. Superior process of the genital cup rectangular (Figs 18–19). Head of the paramere with posterior lobe bifid (Fig. 19).

Description. Head: Antennae yellow (Figs 36–37); antennomeres II+III subequal in length to IV.

Thorax: Pronotum with punctures densely and uniformly distributed (Fig. 36). Coria maculate (Fig. 36). Ventrally with dark irregular spots; punctures dark and small. Evaporatorium dark brown (Fig. 37). Peritreme reaching half of the distance from ostiole to the lateral margin of the metapleuron (Fig. 37). Metasternal process with punctures dark and shallow (Fig. 37) associated with setae; bifurcation receiving most of fourth rostral segment (Figs 16–17). Legs yellow with dark macules on femur (Fig. 37).

Abdomen: Each connexival segment with two faded dark spots on lateral margins (Fig. 36). Ventrally punctures dark and large (Fig. 37).

Male genitalia: Pygophore rectangular (Figs 18, 20). Posterolateral angles developed (Figs 18, 20). Presence of a strip of short setae on the floor of the genital cup laterally to the proctiger. Ventral rim with expansions tumid and projected, reaching apices of posterolateral angles in ventral view (Figs 18, 20). Ventral surface with tumid central area strongly projected posteriorly, reaching beyond the bottom of the excavation of the ventral rim (Figs 18, 20). Phallus . Vesica as broad as distal part of phallotheca with an acuminate projection (Fig. 21).

Female genitalia: Gonocoxites 8 with distal margins arcuate; inner margins slightly divergent (Fig. 22). Laterotergites 8 and 9 with punctures associated with dark spots. Pars intermedialis bottle-shaped. Capsula seminalis with three thick projections (only two visible in the drawing) of different length; one of them with secondary projections (Fig. 23).

Measurements: Total length: 16.0–18.6; head length: 1.8–2.2; head width: 3.0–3.3; pronotum length: 3.3–4.3 pronotum width: 10.5–13.2; humeral angles length: 1.0–1.5; humeral angles width: 1.0–1.2; abdominal width: 8.5– 11.1; length of antennomeres: I: 0.8–1.2; II: 1.1–1.4; III: 1.5–2.3; IV: 3.0–3.7; V: 3.2–3.9.

Comments: Stål (1872) described Edessa sahlbergii from a female collected in Rio de Janeiro, Brazil. Notes from Pieter van Doesburg regarding this species considered the specimen in Stockholm to be the holotype of the species and also did not mention another specimen in any collection with material studied by Stål. Therefore, the female is considered the holotype of the species. This species was included in step “o” of the key (species group “ Edessa ”), among species with wide humeral angles, depressed, rounded anteriorly, and with a ventral surface distinctly punctate (Stål 1872).

Edessa sahlbergii and E. graziae sp. nov. are the only variegated species of the group; both also share the metasternal process with punctures associated with setae and dark spots. But an obvious difference between them are the almost flat and punctured humeral angles of E. sahlbergii . Other differences between both species are subtle, including posterior lobe of the paramere; the shape of superior process of the genital cup; and humeral angle projection. The male of the Edessa sahlbergii is described for the first time.
