Measurements (n= 9). Total length: 20.4–23.6; head length: 1.8–2.3; head width: 3.6–3.7; pronotum length: 3.7–4.1; pronotum width: 12.5–14.1; scutellum length: 9.5–10.9; scutellum width: 7.0–8.0; abdominal width: 12.0– 13.5; length antennomers: I: 1.0–1.0; II: 2.0–2.5; III: 1.5–2.0; IV: 4.5–5.0; V: 5.0.
Diagnosis. Specimens large (20.4–23.6 mm). Dorsal surface green (Fig. 29 E). Ventral surface dark yellow to brown with transversal black lines on thorax and abdomen (Fig. 29 F). Antennae reddish brown (Fig. 29 E). Pronotum with punctures black to brown (Fig. 29 E); anterolateral margin and cicatrices with black punctures (Fig. 29 E). Humeral angles short (2,0 times wider than long) (Fig. 29 E), apices concolorous with surface (Fig. 29 E). Scutellum with brown punctures (Fig. 29 E); apex not reach end of corium (Fig. 29 E). Corium with all veins concolorous with surface (Fig. 29 E). Posterolateral angles of connexivum with apices black (Fig. 29 E); connexival segments with concavities entirely covered by rectangular black spots and separated by a large yellow median spot (Fig. 29 E); spots extending ventrally, triangular (Fig. 29 F). Ventral surface. Thorax with black stripes (Fig. 29 F); dark stripe of the propleuron almost reaching the dark spot of the humeral angle (Fig. 29 F). Evaporatorium concolorous with thorax (Fig. 29 F). Metasternal process (Fig. 23 G) with anterior apex rounded and laterally little expanded, margin rounded; anterior face broadly excavated; anterior bifurcation receiving fourth rostral segment. Legs brown (Fig. 29 F). Abdomen with spine of third segment acuminated (Fig. 23 G). Intersegmental areas brown reaching ventral spots of connexivum (Fig. 29 F). Pseudosutures concolorous with surface (Fig. 29 F). Median longitudinal brown band restricted to last segment (Fig. 29 F). Trichobotria one in line with spiracle and the other laterad. Posterolateral angles of segment VII on the same level the level of apices of laterotergites IX in females (Fig. 23 F). Male genitalia, dorsal side of the pygophore with a suffused brown area occupying 1/3 of the surface (Fig. 23 A,B,D,E). Posterolateral angle of the pygophore developed (Fig. 23 A). Superior process of genital cup laminar, rectangular, thick; flattened, coarse and concave in posterior view; continuing ventrally in a crenulated high carina, ending in a small dentiform projection (Fig. 23 B,E). Anterior half of proctiger brown (Fig. 23 A,B,D,E). Ventral rim with long setae, but without lateral tufts (Fig. 23 C). Female genitalia, valvifers VIII wrinkled (Fig. 23 F). Laterotergites VIII with one dark spots on outer lateral margins (Fig. 23 F).
Male genitalia (Fig. 23 A–E): Parameres with brown margin, anterior lobe rounded; dorsal lobe rounded and subrectangular, little curved at the apex; posterior lobe rounded and subrectangular (Fig. 23 B,D,E). Proctiger with subelliptical posterior face (Fig. 23 D,E). Ventral rim with expansions little developed, rounded, concolorous with surface, the expansions not reaching beyond apices of posterolateral angles (Fig. 23 C).

Female genitalia: Valvifers VIII with dark punctures; inner margins contiguous, with brown band and not divergent; distal margin forming distal U-shaped excavation, with brown band and arched. Laterotergites IX with apices acuminate passing the sclerite uniting laterotergites VIII (Fig. 23 F).
Comments. The Edessa (E.) urus looks like E. (E.) alces, E. (E.) congrua, and E. (E.) sexdens. See comments of E. (E.) alces.
Distribution (Fig. 32 A): BRAZIL: Pará, Amazonas, Rondônia.
