description: Edessa (Edessa) rutilata sp. n.
(Figs. 43, 68 A–B, 74)
Etymology. The name refers to the reddish brown coloration of the body dorsally (L. rutilus, red).
Material examined. Holotype male. BRAZIL, Amazonas: Tonantins, Rio Amazonas, VIII–1923, S. Klages (CMNH).
Measurements (n= 1). Total length: 22.6; head length: 1.8; head width: 3.8; pronotum length: 4.7; pronotum width: 15.0; scutellum length: 10.4; scutellum width: 7.9; abdominal width: 13.0; length antennomeres: I: 1.0; II: 2.2; III: 2.0; IV: 2.2.
Diagnosis. Large (22.6 mm). Dorsal body surface reddish brown, densely punctured (Fig. 68 A). Ventral surface reddish yellow to orange with transversal brown lines on thorax and abdomen (Fig. 68 B). Head with brown spot. Antennae reddish brown (Fig. 68 A–B). Pronotum coarse, with black punctures (Fig. 68 A); anterolateral margin and cicatrices with black punctures. Humeral angles short (1.7 times wider than long); apex with black spot expanding over the pronotal disc in dorsal view and restricted the angles in ventral view; curved backward (Fig. 68 A–B). Scutellum with black punctures; posterior part excavated medially; apex acuminated not reach end of coria (Fig. 68 A). Coria with all veins concolorous with the surrounding surface (Fig. 68 A). Connexival segments with concavities all covered by rectangular black spots separated by a large yellow median spot (Fig. 68 A), spots extending ventrally, triangular (Fig. 68 B). Posterolateral angles of connexivum with apices black (Fig. 68 A). Ventral surface, thorax with brown lines; dark line of the propleura covering 1/3 of the width of the sclerite (Fig. 68 B). Proepisternum with dark line (Fig. 68 B). Evaporatorium concolorous with the surrounding surface (Fig. 68 B). Metasternal process (Fig. 43 F) with arms of anterior bifurcation straight and laterally little expanded at apex; anterior bifurcation somewhat excavated receiving fourth and a small part of the third rostral segment. Legs brown (Fig. 68 B). Abdomen with spine of segment III acuminated (Figs. 43 F; 68 B). Intersegmental areas covered by narrow brown lines with smudged margins, not reaching the lateral spots (Fig. 68 B). Pseudosutures concolorous with the surrounding surface (Fig. 68 B, dark lines are a deterioration of the exoskeleton). Near the spiracle a circular brown spot (Fig. 68 B). Median longitudinal brown band incomplete, restricted to the segment VII (Fig. 68 B). Trichobothria both parallel to the spiracle. Male genitalia, dorsal side of the pygophore with a suffused dark brown area occupying 1/3 of the surface (Fig. 43 A–B). Posterolateral angles of the pygophore developed, projected laterally, apices with spots black (Fig. 43 A–B, E). Superior processes of the genital cup thick, rectangular, in flattened and coarse posterior view, continuing ventrally in a crenulate, short and high carina (Fig. 43 B, E crenulate carina barely visible). Diaphragm with contrasting yellow spot. Parameres (Fig. 43 D–E) with black margins; anterior lobe rounded; dorsal lobe subtriangular with curved apex; posterior lobe inconspicuous, rounded. Proctiger, posterior face subelliptical (Fig. 43 D–E). Ventral surface with dark spot medially (Fig. 43 C). Ventral rim without setae (Fig. 43 C); with expansions undeveloped and concolorous with the surrounding surface (Fig. 43 C). Female genitalia. Unknown.
Comments. See comments on E. (E.) flaviventris sp. n.. Edessa (E.) rutilata sp. n. differs from E. (E.) flaviventris sp. n., E. (E.) fulvomaculata sp. n., and E. (E.) nigrocrocata sp. n. by the coria reddish (the other species with coria no reddish area); dark line of the propleura covering 1/3 of the width of the sclerite (the other species with dark line of the propleura covering 2/3 of the width of the sclerite); dorsal side of the pygophore with a suffused brown area occupying 1/3 of the surface (the other species without such spot); and diaphragm with contrasting yellow spot (the other species without such spot).
Distribution (Fig. 74). BRAZIL: Amazonas.
