Diagnosis. Large (16.0– 18.9 mm). Dorsal body surface green ( Fig. 70 E ). Ventral surface dark yellow to green with transversal green bands on thorax and abdomen ( Fig. 70 F ). Antennae with first brown segment and second to fifth black segment ( Fig. 70 E–F ). Pronotum with concolorous with the surrounding surface punctures; anterolateral margin with a yellow band extending from the humeral angles to the head ( Fig. 70 E ). Humeral angles short (1.25 times wider than long), narrow; apex concolorous with the surrounding surface and strongly curved backward ( Fig. 70 E–F ). Scutellum with concolorous with the surrounding surface punctures; apex not reaching the end of coria ( Fig. 70 E ). Coria with all veins concolorous with the surrounding surface ( Fig. 70 E ). Connexival segments with concavities entirely covered by rectangular green spots and separated by a large yellow median spot ( Fig. 70 E ), spots extending ventrally and green spot forming green bands on the abdomen ( Fig. 70 F ). Posterolateral angles of connexivum with apices green ( Fig. 70 E ). Ventral surface, thorax with green bands; dark band of the propleura connected to the dark spot of the humeral angles ( Fig. 70 F ). Evaporatorium concolorous with the surrounding surface ( Fig. 70 F ). Metasternal process ( Fig. 51 G ) with arms of anterior bifurcation rounded and laterally little expanded at apex; anterior bifurcation somewhat excavated receiving a small part of the third and fourth rostral segment. Legs reddish brown ( Fig. 70 F ).Abdomen with spine of segment III rounded ( Figs. 51 G , 70 F ). Intersegmental areas covered by brown line with adjacent smudged green bands, reaching the lateral spots ( Fig. 70 F ). Pseudosutures concolorous with the surrounding surface ( Fig. 70 F ). Median longitudinal brown band incomplete ( Fig. 70 F ). Trichobothria both parallel to the spiracle. Posterolateral angles of segment VII exceeding the level of apices of laterotergites IX ( Fig. 51 F ). Male genitalia, dorsal side of the pygophore with a suffused dark area occupying 2/3 of the surface ( Fig. 51 A–B ). Posterolateral angles of pygophore slightly developed ( Fig. 51 A–B ). Superior processes of the genital cup rectangular, narrow, higher than the projection and continuing ventrally in a well-developed and narrow projection; this projection with apex extended and truncated ( Fig. 51 B, E ). Parameres ( Fig. 51 D–E ) with brown margin; anterior lobe rounded; dorsal lobe subtriangular, curved toward to superior processes of the genital cup; posterior lobe subrectangular. Proctiger, posterior face triangular ( Fig. 51 D–E ). Ventral rim not setose ( Fig. 51 C ); with expansions developed, rounded, concolorous with the surrounding surface, expansions slightly surpassing apices of posterolateral angles ( Fig. 51 A, C ). Female genitalia, valvifers VIII subrectangular, with concolorous with the surrounding surface punctures; medially near the sutural margins with a green spot, contiguous and not divergent; posterior margin forming a U-shaped excavation. Laterotergites VIII with two green spots on lateral margins. Laterotergites IX with brown spot in the base and apices acuminate passing the mediotergite VIII ( Fig. 51 F ).

Comments. See comments on E. (E.) chloroicterica sp. n.. Edessa (E.) viridifasciata sp. n. differs from E. (E.) chloroicterica sp. n., E. (E.) flavofemorata sp. n., E. (E.) imbecilla (see Mendonça et al., 2023, Fig. 9 C–E ), E. (E.) nigroantennata sp. n., E. (E.) rufofusca sp. n., E. (E.) tuberculata sp. n., and Edessa (E.) viridifasciata sp. n. by the characteristics of the genitalia.

Distribution ( Fig. 72 ). BRAZIL: Amazonas; PERU: Loreto.
