description: Edessa leucocera. Holotype female. Cauca, Colombia, 46 /20 (BMNH). Examined.
Material examined. COSTA RICA, Puntarenas: 2♁, Coronado de Osa, 24-VI-1995, S. Avila (L S 333000 506000) (INBIO); 1♀, P. N. Antônio, Quepos, VII-1991, G. Varela (L S 370900 448800) (INBIO); Guanacaste: 1♁ 1♀, P. N. Santa Rosa, 4–6-XII-1979, D. H. Janzen (Compared with type —Fernandes JAM, 1999) (UFPA).
Measurements (n= 5). Total length: 17.7–18.5; head length: 1.4–1.7; head width: 3.2–3.2; pronotum length: 3.7–3.7; pronotum width: 11.5–12.1; scutellum length: 8.4–8.6; scutellum width: 6.3–6.7; abdominal width: 10.0– 10.2; length antennomers: I: 1.0–1.0; II: 1.2–1.4; III: 1.5–1.9; IV: 3.5–3.5; V: 3.1.
Diagnosis. Specimens large (17.7–18.5 mm). Dorsal surface green (Fig. 27 A). Ventral surface dark yellow to orange with transversal black lines on thorax and abdomen (Fig. 27 B). Antennae brown (Fig. 27 A). Pronotum with punctures brown with surface (Fig. 27 A). Anterolateral angle of pronotum with a yellow band that extends from the humeral angle to the head. Humeral angles long (0,6 times longer than wide) (Fig. 27 A), apices brown (Fig. 27 A); humeral angle brown spot restricted to the angle in dorsal and ventral views (Fig. 27 A,B). Scutellum with punctures brown (Fig. 27 A); apex on the same level end of corium (Fig. 27 A). Corium with all veins concolorous with surface (Fig. 27 A). Posterolateral angles of connexivum with apices concolorous with surface (Fig. 27 A); connexival segments without spot and with a pair of concavities (Fig. 27 A). Ventral surface. Thorax with black stripes (Fig. 27 B); dark stripe of the propleuron covering 2/3 of the width of the sclerite (Fig. 27 B). Proepisternum with dark stripe (Fig. 27 B). Evaporatorium concolorous with thorax (Fig. 27 B). Metasternal process (Fig. 12 G) with anterior apex straight and laterally well expanded, margin acuminated; anterior face broadly excavated; anterior bifurcation receiving fourth and a small part of the third rostral segment. Legs brown (Fig. 27 B). Abdomen with spine of third segment acuminated (Fig. 12 G). Intersegmental areas black, not reaching lateral margin (Fig. 27 B). Pseudosutures solid black, margin well defined (Fig. 27 B). Median longitudinal brown band restricted to last segment (Fig. 27 B). Black circular spot near the spiracles (Fig. 27 B). 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. 12 F). Male genitalia, dorsal side of the pygophore with a suffused brown area occupying 1/3 of the surface (Fig. 12 A,B,D). Posterolateral angle of the pygophore developed (Fig. 12 A). Superior process of genital cup laminar, rectangular, thick; flattened and coarse in posterior view, continuing ventrally in a crenulated short carina (Fig. 12 B,D,E). Ventral rim with long setae. but without lateral tufts (Fig. 12 C). Female genitalia, valvifers VIII with a small rounded projection (Fig. 12 F). Laterotergites VIII with dark band on outer lateral margins (Fig. 12 F).
Male genitalia (Fig. 12 A–E): Parameres with black margin; anterior lobe rounded; dorsal lobe rounded and subrectangular, apex curved; posterior lobe rounded and subtriangular (Fig. 12 B,D,E). Proctiger with subelliptical posterior face (Figs. 12 D,E). Ventral rim with expansions little developed, rounded, concolorous with surface, the expansions not reaching beyond apices of posterolateral angles (Fig. 12 C).
Female genitalia: Valvifers VIII with concolorous with surface punctures; inner margins not contiguous, with brown band and divergent; distal margin forming V-shaped excavation, with a brown band and arched. Laterotergites IX with apices acuminate passing the sclerite uniting laterotergites VIII (Fig. 12 F).
Comments. The male of Edessa (E.) leucocera is described here for the first time. This species is similar to E. (E.) fallenii. See comments of E. (E.) fallenii.
Distribution (Fig. 30 A,B): COSTA RICA: Guanacaste, Puntarenas; COLOMBIA: Cauca.
