Measurements (n= 5). Total length: 20.6–25.2; head length: 1.6–2.4; head width: 3.6–4.0; pronotum length: 4.1–5.0; pronotum width: 14.1–15.7; scutellum length: 9.4–11.3; scutellum width: 7.5–8.7; abdominal width: 11.3– 14.2; length antennomers: I: 1.0–1.0; II: 1.8–2.3; III: 2.0–2.3; IV: 4.0–5.6; V: 3.8.

Diagnosis. Specimens large (20.6–25.2 mm). Dorsal surface green (Fig. 25 C). Ventral surface dark yellow to orange with transversal brown lines on thorax and abdomen (Fig. 25 D). Antennae reddish brown (Fig. 25 D). Pronotum with punctures brown (Fig. 25 C); anterolateral margin and cicatrices with brown punctures (Fig. 25 C). Humeral angles short (1,5 times wider than long) (Fig. 25 C), apices black (Fig. 25 C); humeral angle black spot restricted to the angle in dorsal and ventral views (Fig. 25 C,D). Scutellum with punctures brown (Fig. 25 C), apex not reach end of corium (Fig. 25 C). Corium with all veins concolorous with surface (Fig. 25 C). Posterolateral angles of connexivum with apices black (Fig. 25 C); connexival segments with concavities almost entirely covered by subrectangular brown spots and separated by a large yellow median spot (Fig. 25 C), spots extending ventrally, subrectangular (Fig. 25 D). Ventral surface. Thorax with brown stripes (Fig. 25 D); dark stripe of the propleuron covering 2/3 of the width of the sclerite (Fig. 25 D). Evaporatorium concolorous with thorax (Fig. 25 D). Metasternal processs (Fig. 5 G) with anterior apex straight and laterally well expanded, margin rounded; anterior face somewhat excavated; anterior bifurcation receiving fourth rostral segment. Legs with tibiae and tarsi darker than the rest (Fig. 25 D). Abdomen with spine of third segment acuminated (Fig. 5 G). Intersegmental areas brown reaching ventral spots of connexivum (Fig. 25 D). Pseudosutures concolorous with surface (Fig. 25 D). Median longitudinal brown band restricted to last segment (Fig. 25 D). Trichobotria one in line with spiracle and the other laterad. Posterolateral angles of segment VII not reaching the level of apices of laterotergites IX in females (Fig. 5 F). Male genitalia, posterolateral angle of pygophore very developed (Fig. 5 A). Superior process of genital cup laminar, thick, subrectangular; flattened, grooved and coarse in posterior view, continuing ventrally in a crenulated high carina, ending in a dentiform projection (Fig. 5 A,B,D,E). Ventral rim not setose (Fig. 5 C). Female genitalia, laterotergites VIII with two small dark spots on outer lateral margins (Fig. 5 F).

Male genitalia (Fig. 5 A–E): Parameres with black margin; anterior lobe rounded and subrectangular; dorsal lobe triangular, little, and rounded; posterior lobe subrectangular and rounded (Fig. 5 D,E). Proctiger with subelliptical posterior face (Fig. 5 D,E). Ventral rim with expansions little developed, rounded, concolorous with surface, the expansions not reaching beyond apices of posterolateral angles (Fig. 5 C).

Female genitalia: Valvifers VIII with dark punctures; inner margins contiguous, with brown band and divergent; distal margin with brown band and arched. Laterotergites IX with apices acuminate passing the sclerite uniting laterotergites VIII (Fig. 5 F).

Comments. The Edessa (E.) electa is very similar to E. (E.) nigroangulata . Both species can be separated by the ventral side of the abdomen with intersegmental stripes narrow and brown and pseudosutures concolorous with abdomen in E. (E.) electa (Fig. 25 D) (intersegmental stripes wide and black and pseudosutures brown in E. (E.) nigroangulata — Fig. 28 F). The pygophore of E. (E.) electa (Fig. 5 A) shows the posterolateral angle more acute than in E. (E.) nigroangulata (Fig. 17 A). Also, laterotergites VIII and IX have a distal sharp spine in E. (E.) electa (Fig. 5 F) and a truncate apex in E. (E.) nigroangulata (Fig. 17 F). Furthermore, E. (E.) electa (Fig. 32 A,B) can be found in South America and Panamá and E. (E.) nigroangulata (Fig. 30 A,B) can be found from Costa Rica to Mexico. Possibly Reuter’s mention of E. (E.) fuscidorsata to Mexico refers to E. (E.) nigroangulata .

Distribution (Fig. 32 A,B): PANAMA; COLOMBIA: Bogotá; BRAZIL: Pará, Amazonas, Mato Grosso, Rondônia.
