Edessa fallenii . Lectotype male. Nova Granada [Bogota] ( NHRM). Examined. Here designated.

Edessa fallenii . Paralectotypes. 2 males, 1 female, same data ( NHRM) .

Material examined: PANAMA, Colón: 1♁, Pipeline road, 30-VI-1974, D. Engleman (Compared to the type — Fernandes JAM, 1999) ( DOE) ; 1♁, Canal Zone , Glrenco col. ( USNM) . VENEZUELA, Caracas: 1♀, La Salle College , B. C. Freneo col. ( USNM) ; 1♀, No date—(Compared to the type, Fernandes JAM, 1999), J. A. M. Fernandes, 1999 ( MNHN) .

Measurements (n= 4). Total length: 19.2–19.5; head length: 1.6–1.6; head width: 3.3–3.2; pronotum length: 3.8–4.1; pronotum width: 13.7–13.9; scutellum length: 8.4–8.7; scutellum width: 6.4–6.7; abdominal width: 10.3– 10.9; length antennomers: I: 0.9–1.0; II: 1.5; III: 1.7; IV: 3.6; V: 3.8.

Diagnosis. Specimens large (19.2–19.5 mm). Dorsal surface green ( Fig. 25 E View FIGURE 25 ). Ventral surface dark yellow to brown with transversal black lines on thorax and abdomen ( Fig. 25 F View FIGURE 25 ). Antennae brown ( Fig. 25 E View FIGURE 25 ). Pronotum with punctures concolorous with surface to brown ( Fig. 25 E View FIGURE 25 ). Humeral angles short (1.3 times wider than long) ( Fig. 25 E View FIGURE 25 ), apices brown ( Fig. 25 E View FIGURE 25 ); humeral angle brown spot expanding into the pronotum in dorsal and ventral views ( Fig. 25 E,F View FIGURE 25 ). Scutellum with punctures brown ( Fig. 25 E View FIGURE 25 ); apex not reach end of corium ( Fig. 25 E View FIGURE 25 ). Corium with all veins concolorous with surface ( Fig. 25 E View FIGURE 25 ). Posterolateral angles of connexivum with apices concolorous with surface ( Fig. 25 E View FIGURE 25 ); connexival segments without spot and flat ( Fig. 25 E View FIGURE 25 ). Ventral surface. Thorax with black stripes ( Fig. 25 F View FIGURE 25 ); dark stripe of the propleuron covering 2/3 of the width of the sclerite ( Fig. 25 F View FIGURE 25 ). Proepisternum with dark stripe ( Fig. 25 F View FIGURE 25 ). Evaporatorium concolorous with thorax ( Fig. 25 F View FIGURE 25 ). Metasternal process ( Fig. 6 G View FIGURE 6 ) with anterior apex straight and laterally little expanded, margin rounded; anterior face somewhat excavated; anterior bifurcation receiving fourth rostral segment. Legs brown ( Fig. 25 F View FIGURE 25 ). Abdomen with spine of third segment acuminated ( Fig. 6 G View FIGURE 6 ). Intersegmental areas black not reaching lateral margin ( Fig. 25 F View FIGURE 25 ). Pseudosutures partially covered by superficial black stripe ( Fig. 25 F View FIGURE 25 ). Median longitudinal brown band restricted to last segment ( Fig. 25 F View FIGURE 25 ). 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. 6 F View FIGURE 6 ). Male genitalia, dorsal side of the pygophore with a suffused brown area occupying 1/3 of the surface ( Fig. 6 A,B,D,F View FIGURE 6 ). Posterolateral angle of the pygophore developed ( Fig. 6 A View FIGURE 6 ). Superior process of genital cup laminar, narrow, short, rectangular; flattened and coarse in posterior view, continuing ventrally in a crenulated high carina ( Fig. 6 A,B,E View FIGURE 6 ). Ventral rim not setose ( Fig. 6 C View FIGURE 6 ). Female genitalia, valvifers VIII with distal margin with a small dentiform projection on the valvifers IX ( Fig. 6 F View FIGURE 6 ); tumescence in the central region of valvifers VIII with a brown spot ( Fig. 6 F View FIGURE 6 ). Laterotergites VIII with dark band on outer posterior margins ( Fig. 6 F View FIGURE 6 ).

Male genitalia ( Fig. 6 A–E View FIGURE 6 ): Parameres with brown margin; anterior lobe rounded; dorsal lobe rounded and subtriangular, curved apex; posterior lobe rounded and subtriangular ( Fig. 6 D,E View FIGURE 6 ). Proctiger with subelliptical posterior face ( Fig. 6 D,E View FIGURE 6 ). Ventral rim with expansions undeveloped and brown ( Fig. 6 C View FIGURE 6 ).

Female genitalia: Valvifers VIII with dark punctures; inner margins contiguous and not divergent; distal margin arched and forming distal U-shaped excavation. Laterotergites IX with apices acuminate passing the sclerite uniting laterotergites VIII ( Fig. 6 F View FIGURE 6 ).

Comments. The Edessa (E.) fallenii shares with E. (E.) leucocera and E. (E.) phoenicopus the humeral angles concolorous with pronotum and connexival segments spotless ( Fig. 25 E View FIGURE 25 ). The first two species are more similar but can be separated by the humeral angle slightly longer and apex of scutellum far from the end of corium in E. (E.) fallenii ( Fig. 25 E View FIGURE 25 ) (humeral angle shorter and apex of scutellum almost reaching the end of corium in E. (E.) leucocera — Fig. 27 A View FIGURE 27 ). E. (E.) fallenii can be separated from E. (E.) phoenicopus by the humeral angle less developed and corial veins concolorous with corium ( Fig. 25 E View FIGURE 25 ) (humeral angles robust and corial veins yellow in E. (E.) phoenicopus — Fig. 29 A View FIGURE 29 ).
