Treatment

Edessa (Edessa) illuminocornis sp. n.

( Figs. 23 View FIGURE 23 , 61 C–D View FIGURE 61 , 74 View FIGURE 74 )

Etymology. The name refers to the black humeral angles (L. illuminus, without light, dark; L. cornu, horn).

Material examined. Holotype female. BRAZIL, Rondônia: Fazenda Rancho Grande 62 km SW, 6–15-XII-1990, D. A. Rider & J.E. Eger ( INPA).

Measurements (n= 1). Total length: 20.7; head length: 1.9; head width: 3.7; pronotum length: 4.1; pronotum width: 15.5; scutellum length: 9.6; scutellum width: 7.2; abdominal width: 11.5; length antennomeres: I: 1.0; II: 1.6; III: 2.3; IV: 4.6; V: 5.2.

Diagnosis. Large (20.7 mm). Dorsal body surface olive green ( Fig. 61 C View FIGURE 61 ). Ventral surface dark yellow to brown with transversal brown bands on thorax and abdomen ( Fig. 61 D View FIGURE 61 ). Antennae reddish brown ( Fig. 61 C–D View FIGURE 61 ). Pronotum with brown punctures ( Fig. 61 C View FIGURE 61 ); anterolateral margin and cicatrices with brown punctures. Humeral angles (as long as wide); apex with black spot restricted to the angles in dorsal view and restricted to the margin of the angles in ventral view; slightly bent backward ( Fig. 61 C–D View FIGURE 61 ). Scutellum with brown punctures; posterior part excavated medially; apex not reaching the end of coria ( Fig. 61 C View FIGURE 61 ). Coria with all veins yellow ( Fig. 61 C View FIGURE 61 ). Connexival segments with concavities slightly covered by elliptical brown spots ( Fig. 61 C View FIGURE 61 ), spots not extending ventrally ( Fig. 61 D View FIGURE 61 ). Posterolateral angles of connexivum with apices brown ( Fig. 61 C View FIGURE 61 ). Ventral surface, thorax with brown bands; dark band of the propleura covering 1/3 of the width of the sclerite ( Fig. 61 D View FIGURE 61 ). Proepisternum densely punctured, with dark band ( Fig. 61 D View FIGURE 61 ). Evaporatorium concolorous with the surrounding surface ( Fig. 61 D View FIGURE 61 ). Metasternal process ( Fig. 23 B View FIGURE 23 ) with arms of anterior bifurcation straight and laterally well expanded at apex; anterior bifurcation somewhat excavated deep, receiving fourth and half of the third rostral segment ( Fig. 61 D View FIGURE 61 ). Legs with tibiae and tarsi reddish, remaining yellow ( Fig. 61 D View FIGURE 61 ). Abdomen with spine of segment III rounded ( Figs. 23 B View FIGURE 23 , 61 D View FIGURE 61 ). Intersegmental areas covered by narrow smoky brown bands with smudged margins, not reaching lateral margin ( Fig. 61 D View FIGURE 61 ). Pseudosutures smoky brown with irregular margins ( Fig. 61 D View FIGURE 61 ). Median longitudinal brown band incomplete, restricted to the segment VII ( Fig. 61 D View FIGURE 61 ). Trichobothria one in line with spiracle and the other laterad. Posterolateral angles of segment VII exceeding the level of apices of laterotergites IX ( Fig. 23 A View FIGURE 23 ). Male genitalia. Unknown. Female genitalia, valvifers VIII with dark punctures, well projected to the laterotergites IX, spiny projection, a rounded and inconspicuous central projection that projects to the valvifers IX; tumescence with a brown spot; sutural margins contiguous, brown and not divergent; posterior margin brown and forming distal U-shaped excavation, leaving part of the valvulae IX exposed. Laterotergites VIII with brown spot near the spiracle and dark band on outer lateral margins. Laterotergites IX with brown spot in the base and apices acuminate passing the mediotergite VIII ( Fig. 23 A View FIGURE 23 ).

Comments. See comments on E. (E.) atricornis sp. n.. Edessa (E.) illuminocornis differs from E. (E.) atricornis sp. n., E. (E.) fuliginocornis sp. n., and E. (E.) maurocornis sp. n. by the arms of anterior bifurcation the metasternal process deep, with apex wide and laterally well expanded (arms of anterior bifurcation the metasternal process shallow, with apex narrow and laterally little expanded in the other species).
