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 ).

[...... Continues on page 60]

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.
