Measurements. antennomeres length: 1st: 0.6–0.8; 2nd: 1.7–1.9; 3rd: 1.2–1.4; 4th: 2.7; 5th: 2.8; head length: 1.3–1.9; head width: 2.5–2.7; pronotal length: 2.5–3.0; pronotal width: 7.6–8.5; scutellum length: 5.1–6.2; scutellum width: 4.5–5.0; abdominal width: 7.4–8.3; total length: 14–15.3.

Diagnosis. Dorsal surface moss green with orange markings ( Fig. 5E ); ventral surface greenish yellow to green ( Fig. 5F ). Antennal segment I green with distal part black ( Fig. 5E ); other segments black with basal ring green on segments III and IV; antennal segment II longer than III. Anterolateral margins of pronotum orange ( Fig. 5E ). Corium green except for light brown lines parallel to claval sutures ( Fig. 5E ); broad brown stripe found in other species of this group lacking in this species. Punctures of coria concolorous with surface, except for two rows of brown punctures parallel to claval sutures ( Fig. 5E ). Pygophore with posterolateral angles projected, rounded and extremely tumid ( Fig. 3A,B ). Gonocoxites 9 strongly compressed laterally ( Fig. 3D ).

Description. Head. Apices of mandibular plates green.

Thorax. Orange spot on apex of each humeral angle ( Fig. 5E ). Scutellum with apex punctate.Anterolateral margin of each corium concolorous, without dark spot ( Fig. 5E ). Coria with shallow punctation. Veins of coria slightly lighter than background. Membrane of hemelytra dark brown ( Fig. 5E ). Ventral surface with shallow, concolorous punctation ( Fig. 5F ).

Abdomen. Distal margin of each seventh abdominal segment green, only spinose apex black ( Fig. 5E ).

Male ( Fig. 3 A–C). Dorsal rim of pygophore slightly projected, slightly darker than dorsal surface, ending in a suture separating it from each posterolateral angle ( Fig. 3A ). Superior process of the genital cup small, slanting, tongue-like, yellow, with distal part posteriorly directed. Parameres each with anterior lobe tongue-like, almost reaching diaphragm; posterior lobe short, truncate distally, curved laterally, touching posterolateral angle ( Fig. 3B ). Proctiger posterolaterally excavated, with longitudinal keel between dorsal surface and posterior face, dorsally delimited by brown developed keel; posterior face very small and triangular ( Fig. 3B ). Ventral rim with a medial shallow excavation delimited by acuminated, slightly tumid, and well-developed expansions not reaching level of posterolateral angles in ventral view ( Fig. 3C ). Ventral surface densely punctured, rugose medially.

Female ( Fig. 3D ). Gonocoxites 8 slightly convex, outer lateral margins rounded, distally projected, reach- ing middle of laterotergites 9; mesial borders not projected posteriorly. Gonocoxites 9 with a small protuberance adjacent to mesial borders. Laterotergites 9 each with base shallowly concave; barely surpassing sclerite uniting laterotergites 8.

Comments. This species is more closely related to Edessa brunneofasciata sp. n. because of similar male genitalic characteristics such as: parameres large, forming two projections: one dorsally directed and the other curved laterally which fits between the tumescence of the inner surface of the lateral angles and the expansions of the ventral rim ( Figs. 3B ; 4B ); the ventral rim with a medial shallow excavation delimited by small rounded expansions ( Figs. 3C ; 4C ). This species can be differentiated from E. brunneofasciata sp. n. by its distinct mossy green and orange coloration, the length of the parameres that partially “embrace” the tumid adjacent posterolateral angle, the proctiger extremely excavated laterally, and by the small posterior face of the proctiger ( Figs. 3B ; 4B ).

Distribution ( Fig.6 ). COSTA RICA: Puntarenas; PANAMA: Chiriquí.
