Measurements (n= 28). Total length: 13.2–22.5; head length: 2.0–2.2; head width: 3.4–3.8; pronotum length: 3.6–4.3; pronotum width: 14.1–20.2; scutellum length: 7.3–10.3; scutellum width: 6.0–7.7; abdominal width: 9.0– 11.3; length antennomers: I: 1.0–1.0; II: 1.4–1.6; III: 2.5–3.4; IV: 4.3–5.0; V: 4.0–5.0.
Diagnosis. Specimens large (13.2–22.5 mm). Dorsal surface green (Fig. 25 A). Ventral surface yellow to green with transversal brown lines on thorax and abdomen (Fig. 25 B). Antennae reddish brown (Fig. 25 A). Pronotum with punctures concolorous with surface to brown (Fig. 25 A); posterior margin of the pronotum with dentiform projection (Fig. 25 A). Humeral angles long (1,5 times longer than wide) (Fig. 25 A), apices dark brown and not recurved (Fig. 25 A); humeral angle dark spot restricted to the angle in dorsal and ventral views (Fig. 25 A,B). Scutellum with punctures concolorous with surface to brown (Fig. 25 A); apex not reach end of corium (Fig. 25 A). Corium with all veins yellow (Fig. 25 A). Posterolateral angles of connexivum with apices brown (Fig. 25 A); connexival segments without spot and with a pair of concavities (Fig. 25 A). Ventral surface. Thorax with brown stripes (Fig. 25 B); dark stripe of the propleuron covering 1/3 of the width of the sclerite (Fig. 25 B) Evaporatorium concolorous with thorax (Fig. 25 B). Metasternal process (Fig. 4 G) with anterior apex rounded and laterally well expanded, margin rounded; anterior face somewhat excavated; anterior bifurcation receiving fourth and a small part of the third rostral segment. Legs with tibiae and tarsi darker than the rest (Fig. 25 B). Abdomen with spine of third segment rounded (Fig. 4 G). Intersegmental areas brown, not reaching lateral margin (Fig. 25 B). Pseudosutures concolorous with surface (Fig. 25 B). Without median longitudinal brown band (Fig. 25 B). Trichobotria parallel to the spiracle. Posterolateral angles of segment VII not reaching the level of apices of laterotergites IX in females (Fig. 4 F). Male genitalia, pygophore more wider than long (Fig. 4 A,B,C). Posterolateral angle of pygophore slightly developed (Fig. 4 A). Superior process of genital cup laminar, subrectangular, thick; flattened, coarse and concave in posterior view, not continuing ventrally in a carina (Fig. 4 B,D,E). Proctiger with little dense band of short setae along the edge of the subtriangular posterior face (Fig. 4 D,E); diaphragma with contrastingly yellow spot (Fig. 4 B,D,E). Ventral rim without setose (Fig. 4 C). Female genitalia, valvifers VIII with a small dentiform projection that projects to the valvifers IX (Fig. 4 F); presence of a brown spot near inner margins (Fig. 4 F). Laterotergites VIII with dark band on outer lateral margins (Fig. 4 F).
Male genitalia (Fig. 4 A–E): Parameres with black margin; anterior lobe rounded and subtriangular, with curved apex for the proctiger; dorsal lobe subtriangular and rounded; posterior lobe subrectangular and rounded (Fig. 4 B,D,E). Proctiger with subtriangular posterior face (Fig. 4 D,E). Ventral rim with expansions little developed, rounded, concolorous with surface, being a straight margin that joins the posterolateral angles with the ventral rim projection (Fig. 4 C).
Female genitalia: Valvifers VIII with dark punctures and setulose; inner margins contiguous, with brown band and not divergent; distal margin with brown and arched. Laterotergites IX with apices acuminate passing the sclerite uniting laterotergites VIII (Fig. 4 F).
Comments. The male of Edessa (E.) cylindricornis is described here for the first time. This species is unique in E. sexdens group, no other species has humeral angles straight and directed lateroanteriorly (Fig. 25 A,B), corial veins yellow (Fig. 25 A), and connexival segments spotless (Fig. 25 A).
