Edessa (Edessa) humerorotunda sp. n.

( Figs. 22 View FIGURE 22 , 61 A–B View FIGURE 61 , 72 View FIGURE 72 )

Etymology. The name refers to the rounded shape of the humeral angles (L. humerus, shoulder; L. rotundus, spherical).

Material examined. Holotype male. BRAZIL, Amazonas : Ceplac, Rod. AM-01 km 30, 7-V-1970, I. S. Gorayeb ( INPA).

Measurements (n= 1). Total length: 19.3; head length: 1.8; head width: 3.8; pronotum length: 4.3; pronotum width: 14.0; scutellum length: 8.8; scutellum width: 7.0; abdominal width: 10.5; length antennomeres: I: 1.0; II: 2.0; III: 2.0; IV: 4.5.

Diagnosis. Large (19.3 mm). Dorsal body surface olive green, densely punctured ( Fig. 61 A View FIGURE 61 ). Ventral surface dark yellow to brown with transversal black bands on thorax and abdomen ( Fig. 61 B View FIGURE 61 ). Head with concolorous with the surrounding surface to brown punctures. Antennae reddish brown ( Fig. 61 A View FIGURE 61 ). Pronotum with brown punctures ( Fig. 61 A View FIGURE 61 ); anterolateral margin and cicatrices with black punctures. Humeral angles short (1.2 times wider than long); apex with dark brown restricted to the angles in dorsal view; slightly bent backward ( Fig. 61 A–B View FIGURE 61 ). Scutellum with brown to black punctures; posterior part excavated medially; apex not reaching the end of coria ( Fig. 61 A View FIGURE 61 ). Coria with all veins concolorous with the surrounding surface ( Fig. 61 A View FIGURE 61 ). Connexival segments with concavities almost entirely covered by subrectangular black spots separated by a large yellow median spot ( Fig. 61 A View FIGURE 61 ), spots extending ventrally, subrectangular ( Fig. 61 B View FIGURE 61 ). Posterolateral angles of connexivum with apices black ( Fig. 61 A View FIGURE 61 ). Ventral surface, thorax with black bands; dark band of the propleura covering 2/3 of the width of the sclerite ( Fig. 61 B View FIGURE 61 ). Proepisternum, densely punctured, with dark band ( Fig. 60 B View FIGURE 60 ). Evaporatorium concolorous with the surrounding surface ( Fig. 61 B View FIGURE 61 ). Metasternal process ( Fig. 22 F View FIGURE 22 ) with arms of anterior bifurcation straight and laterally well expanded at apex; anterior bifurcation slightly excavated receiving fourth and a small part of the third rostral segment. Legs with tibiae and tarsi reddish, remaining yellow to orange ( Fig. 61 B View FIGURE 61 ). Abdomen with spine of segment III rounded ( Figs. 22 F View FIGURE 22 ; 61 B View FIGURE 61 ). Intersegmental areas covered by narrow solid black bands with well-defined margins, reaching the lateral spots ( Fig. 61 B View FIGURE 61 ). Pseudosutures solid black with well-defined margins ( Fig. 61 B View FIGURE 61 ). Median longitudinal black band incomplete ( Fig. 61 B View FIGURE 61 ). Trichobothria both parallel to the spiracle.

Male genitalia, posterolateral angles of the pygophore developed, projected laterally, apices internally with spots blacks ( Fig. 22 A–C View FIGURE 22 ). Superior processes of the genital cup subrectangular, thick, in flattened, coarse and slightly concave posterior view, continuing ventrally in a crenulate, long and high carina ( Fig. 22 B, D–E View FIGURE 22 , crenulate carina barely visible). Parameres ( Fig. 22 D–E View FIGURE 22 ) with black margins; anterior lobe rounded; dorsal lobe subtriangular; posterior lobe subrectangular, with curved apex. Proctiger, posterior face subtriangular, reddish posterior half ( Fig. 22 D–E View FIGURE 22 ). Ventral surface densely punctuated; presence of dark spots laterally and medially ( Fig. 22 C View FIGURE 22 ). Ventral rim setose, with medial tuft ( Fig. 22 A, C–E View FIGURE 22 ); with expansions undeveloped and brown ( Fig. 22 C View FIGURE 22 ). Female genitalia. Unknown.
