Measurements (n= 5). Total length: 18.2–20.5; head length: 1.5–1.9; head width: 3.3–3.7; pronotum length: 3.6–4.0; pronotum width: 15.3–16.5; scutellum length: 8.2–9.5; scutellum width: 7.0–7.7; abdominal width: 10.5– 12.0; length antennomeres: I: 1.0; II: 1.8; III: 2.0–2.1; IV: 3.9–4.4; V: 5.0.

Diagnosis. Large (18.2–20.5 mm). Dorsal body surface green ( Fig. 58 E ). Ventral surface dark yellow to brown with transversal black bands on thorax and abdomen ( Fig. 58 F ). Head with black punctures. Antennae yellow ( Fig. 58 E ). Pronotum with black to brown punctures ( Fig. 58 E ); anterolateral margin and cicatrices with black punctures. Humeral angles short (1.25 times wider than long); apex with black spot expanding slightly over the pronotal disc in dorsal view and restricted to the angles in ventral view; anteriorly directed then curved backward ( Fig. 58 E–F ). Scutellum with brown punctures; apex not reaching the end of coria ( Fig. 58 E ). Coria with veins concolorous with the surrounding surface ( Fig. 58 E ). Connexival segments with concavities entirely covered by rectangular black spots separated by a large yellow median spot ( Fig. 58 E ), spots extending ventrally, subrectangular ( Fig. 58 F ). Posterolateral angles of connexivum with apices black ( Fig. 58 E ). Ventral surface, thorax with black bands; dark band of the propleura covering 2/3 of the width of the sclerite ( Fig. 58 F ). Proepisternum densely punctured. Evaporatorium concolorous with the surrounding surface ( Fig. 58 F ). Metasternal process ( Fig. 15 G ) with arms of anterior apex rounded and laterally barely expanded at apex; anterior bifurcation slightly excavated receiving fourth rostral segment. Legs with tibiae and tarsi reddish, remaining yellow to orange ( Fig. 58 F ). Abdomen with spine of segment III rounded. Intersegmental areas covered by wide solid black bands with well-defined margins, reaching the lateral spots ( Fig. 58 F ). Pseudosutures solid black with well-defined margins ( Fig. 58 F ). Near the spiracle there is a circular yellow spot ( Fig. 58 F ). Median longitudinal brown band incomplete, restricted to the segment VII ( Fig. 58 F ). Trichobothria both parallel to the spiracle. Posterolateral angles of segment VII exceeding the level of apices of laterotergites IX ( Fig. 15 F ). Male genitalia, posterolateral angles of the pygophore developed, projected laterally, apices with spots blacks ( Fig. 15 A–B ). Superior processes of the genital cup rectangular, thick, in flattened and coarse posterior view, continuing ventrally in a crenulate high carina ( Fig. 15 B , crenulate carina barely visible). Diaphragm with contrasting yellow spot ( Fig. 15 D–E ). Parameres ( Fig. 15 D–E ) with black margins; anterior, dorsal and posterior lobes rounded. Proctiger, posterior face subelliptical ( Fig. 15 D–E ). Ventral rim with short setae but without a lateral tuft ( Fig. 15 C ); with expansions little developed, rounded, concolorous with the surrounding surface ( Fig. 15 C ). Female genitalia, valvifers VIII with concolorous with the surrounding surface punctures; sutural margins contiguous brown and not divergent; posterior margin brown and arched. Valvifers IX not carinated. Laterotergites VIII with two dark spots on outer lateral margins and a small yellow spot in middle of the margins. Laterotergites IX with apices acuminate passing the mediotergite VIII ( Fig. 15 F ).

Comments. See comments on E. (E.) fabricii sp. n.. Edessa (E.) flavoantennata sp. n. differs from E. (E.) fabricii sp. n. and E. (E.) reuteri sp. n. by the black spot on the humeral angles expanding slightly over the pronotum in dorsal view ( E. (E.) fabricii sp. n. and E. (E.) reuteri sp. n. have the black spot on the humeral angles restricted to the angles in dorsal view); pygophore with ventral rim setulose, but without a lateral tuft ( E. (E.) fabricii sp. n. with lateral tuft); and diaphragm with contrasting yellow spot (the other species without such spot).

Distribution ( Fig. 73 ). COSTA RICA: Limón.
