Edessa (Edessa) fulvomaculata sp. n.

( Figs. 18 View FIGURE 18 , 59 E–F View FIGURE 59 , 73 View FIGURE 73 )

Etymology. The name refers to the orange coloration of the central spot of the connexivum segments (L. fulvus, tawny, reddish yellow; L. macula, spot).

Material examined. Holotype male. BRAZIL, Amazonas : Tefé, X-1958, Dirings ( MZUSP).

Paratype. BRAZIL, Amazonas: 1♀, Tefé , IV-1959, Dirings ( MZUSP) .

Measurements (n= 2). Total length: 21.2–23.8; head length: 1.8; head width: 3.8–4.0; pronotum length: 4.3–5.0; pronotum width: 15.0–15.5; scutellum length: 10.4–11,0; scutellum width: 7.7–8.0; abdominal width: 12.4–14.0; length antennomeres: I: 1.0; II: 1.9–2.5; III: 2.0–2.3; IV: 4.8–5.0.

Diagnosis. Large (21.2–23.8 mm). Dorsal body surface reddish brown ( Fig. 59 E View FIGURE 59 ). Ventral surface orange to reddish brown with transversal black lines on thorax and abdomen ( Fig. 59 F View FIGURE 59 ). Antennae reddish brown ( Fig. 59 E–F View FIGURE 59 ). Pronotum with black punctures ( Fig. 59 E View FIGURE 59 ); 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; curved backward ( Fig. 59 E–F View FIGURE 59 ). Scutellum with black punctures; posterior part excavated medially; apex not reaching the end of coria ( Fig. 59 E View FIGURE 59 ). Coria with all veins concolorous with the surrounding surface ( Fig. 59 E View FIGURE 59 ). Connexival segments with concavities entirely covered by rectangular black spots separated by a large orange median spot ( Fig. 59 E View FIGURE 59 ), spots extending ventrally, triangular ( Fig. 59 F View FIGURE 59 ). Posterolateral angles of connexivum with apices black ( Fig. 59 E View FIGURE 59 ). Ventral surface, thorax with black lines; dark line of the propleura covering 2/3 of the width of the sclerite ( Fig. 59 F View FIGURE 59 ). Evaporatorium concolorous with the surrounding surface; peritreme straight ( Fig. 59 F View FIGURE 59 ). Metasternal process ( Fig. 18 G View FIGURE 18 ) with arms of anterior bifurcation straight and laterally expanded at apex; anterior bifurcation slightly excavated receiving fourth rostral segment. Legs reddish brown ( Fig. 59 F View FIGURE 59 ). Abdomen with spine of segment III rounded ( Figs. 18 G View FIGURE 18 ; 59 F View FIGURE 59 ). Intersegmental areas covered by narrow brown line with smudged margins, not reaching the lateral spots ( Fig. 59 F View FIGURE 59 ). Pseudosutures concolorous with the surrounding surface ( Fig. 59 F View FIGURE 59 , dark lines are a deterioration of the exoskeleton). Median longitudinal brown band incomplete, restricted to the segment VII ( Fig. 59 F View FIGURE 59 ). Trichobothria both parallel to the spiracle. Posterolateral angles of segment VII not reaching the level of apices of laterotergites IX ( Fig. 18 F View FIGURE 18 ). Male genitalia, dorsal rim of pygophore with margin straight ( Fig. 18 A–B View FIGURE 18 ) Posterolateral angles of pygophore very developed, projected laterally ( Fig. 18 A–B View FIGURE 18 ). Superior processes of the genital cup thick, rectangular, in flattened, coarse and concave posterior view, continuing ventrally in a crenulate high carina, ending in a develop dentiform projection ( Fig. 18 A–B, E View FIGURE 18 crenulate carina barely visible). Parameres ( Fig. 18 D–E View FIGURE 18 ) with black margins; anterior lobe rounded; dorsal lobe rounded with curved apex; posterior lobe subrectangular. Proctiger, posterior face subelliptical ( Fig. 18 D–E View FIGURE 18 ). Ventral rim with somewhat long setae but without a lateral tuft ( Fig. 18 C View FIGURE 18 ); with expansions little developed, rounded, concolorous with the surrounding surface ( Fig. 18 C View FIGURE 18 ). Female genitalia, valvifers VIII with concolorous with the surrounding surface punctures; sutural margins contiguous, brown, and not divergent; posterior margin in V-shaped excavation, brown and arched. Laterotergites VIII with two dark spots on outer lateral margins. Laterotergites IX with apices rounded passing the mediotergite VIII ( Fig. 18 F View FIGURE 18 ).

Comments. See comments on E. (E.) flaviventris sp. n.. Edessa (E.) fulvomaculata sp. n. differs from E. (E.) flaviventris sp. n., E. (E.) nigrocrocata sp. n., and E. (E.) rutilata sp. n. by the proepisternum without dark line (proepisternum with dark line in the other species).

Distribution ( Fig. 73 View FIGURE 73 ). BRAZIL: Amazonas.
