description: Edessa (Edessa) nigrocrocata sp. n.
(Figs. 36, 65 E–F, 74)
Etymology. The name refers to the black and yellow to orange color of the connexival segments (L. nigro, black; L. crocatus, saffronlike, saffron-yellow).
Material examined. Holotype male. BRAZIL, Amazonas: S„o Gabriel, Rio Negro, 4-XII-1927, J. F. Zikán (CEIOC).
Paratype. BRAZIL, Amazonas: 1♀, same data as holotype (CEIOC).
Measurements (n= 2). Total length: 21.9–23.7; head length: 1.5–1.9; head width: 3.5; pronotum length: 4.0– 4.4; pronotum width: 14.5–15.2; scutellum length: 10.9; scutellum width: 7.6–8.1; abdominal width: 12.5–14.0; length antennomeres: I: 1.0; II: 1.9–2.0; III: 1.9–2.0; IV: 4.4–4.5.
Diagnosis. Large (21.9–23.7 mm). Dorsal body surface reddish brown, densely punctured (Fig. 65 E). Ventral surface reddish brown with transversal black lines on thorax and abdomen (Fig. 65 F). Antennae reddish brown (Fig. 65 E–F). Pronotum with black punctures (Fig. 65 E); anterolateral margin and cicatrices with black punctures. Humeral angles short (1.5 times wider than long); apex with black spot expanding over the pronotal disc in dorsal view and restricted to the angles in ventral view; slightly curved backward (Fig. 65 E–F). Scutellum with black punctures; posterior part excavated medially; apex acute, not reach end of coria (Fig. 65 E). Coria with all veins concolorous with the surrounding surface (Fig. 65 E). Connexival segments with concavities entirely covered by rectangular black spots separated by a large yellow to orange median spot (Fig. 65 E), spots extending ventrally, triangular (Fig. 65 F). Posterolateral angles of connexivum with apices black (Fig. 65 E). Ventral surface, thorax with black lines; dark line of the propleura covering 2/3 of the width of the sclerite (Fig. 65 F). Proepisternum with dark line (Fig. 65 F). Evaporatorium concolorous with the surrounding surface; peritreme straight (Fig. 65 F). Metasternal process (Fig. 36 G) with arms of anterior bifurcation straight and laterally expanded at apex; anterior bifurcation broadly excavated receiving fourth rostral segment. Legs brown (Fig. 65 F). Abdomen with spine of segment III acuminated (Fig. 36 G). Intersegmental areas covered by narrow brown lines with smudged margins, not reaching the lateral spots (Fig. 65 F). Pseudosutures concolorous with the surrounding surface (Fig. 65 F, dark lines are a deterioration of the exoskeleton). Median longitudinal brown band incomplete, restricted to the segment VII (Fig. 65 F). Trichobothria both parallel to the spiracle. Posterolateral angles of segment VII exceeding the level of apices of laterotergites IX (Fig. 36 F). Male genitalia, dorsal rim with margin straight (Fig. 36 A). Posterolateral angles of pygophore very developed, well projected laterally (Fig. 36 A–C). Superior processes of the genital cup thick, rectangular, flattened and coarse in posterior view, continuing ventrally in a crenulate high carina, ending in a developed dentiform projection (Fig. 36 B, E, crenulate carina and dentiform projection barely visible). Diaphragm setulose (Fig. 36 D–E). Parameres (Fig. 36 D–E) with black margins; anterior lobe rounded; dorsal lobe subrectangular with curved apex; posterior lobe subrectangular. Proctiger, posterior face subelliptical (Fig. 36 D–E). Ventral rim with long setae but without a lateral tuft (Fig. 36 C); with expansions undeveloped and concolorous with the surrounding surface (Fig. 36 C). Female genitalia, valvifers VIII subrectangular, with concolorous with the surrounding surface punctures; sutural margins contiguous brown and not divergent; posterior margin in open U-shaped excavation and brown. Laterotergites VIII with one small dark spot on lateral margins. Laterotergites IX with apices rounded passing the mediotergite VIII (Fig. 36 F).
