Edessa (Edessa) redunca sp. n.
( Figs. 40 View FIGURE 40 , 67 A–B View FIGURE 67 , 73 View FIGURE 73 )
Etymology. The name refers to the humeral angles projected backward (L. reduncus, bent or curved backward).
Material examined. Holotype male. BRAZIL, Amazonas : Tapuruquara, Rio Negro, 20–25-XI-1962, J. Bechyne col. ( MZUSP).
Paratypes. BRAZIL, Amazonas: 1♀ 1♁, Ilha Jerusalem, Rio Negro , 12-V-1964, J. & B. Bechyne ( MPEG) .
Measurements (n= 3). Total length: 21.4–22.4; head length: 1.5–2.5; head width: 3.7–3.8; pronotum length: 4.0–4.5; pronotum width: 13.6–14.8; scutellum length: 10.2–10.6; scutellum width: 7.3–7.8; abdominal width: 11.7–12.2; length antennomeres: I: 1.0; II: 1.5–2.0; III: 2.0; IV: 3.5–3.8; V: 4.0.
Diagnosis. Large (21.4–22.4 mm). Dorsal body surface green, densely punctured ( Fig. 67 A View FIGURE 67 ). Ventral surface dark yellow with transversal black lines on thorax and abdomen ( Fig. 67 C View FIGURE 67 ). Head with brown spot.Antennae reddish brown ( Fig. 67 A–B View FIGURE 67 ). Pronotum coarse, with brown punctures. ( Fig. 67 A View FIGURE 67 ). Humeral angles short (1.3 times wider than long); apex with black spot restricted to the angles in dorsal and ventral views; bent backward ( Fig. 67 A–B View FIGURE 67 ). Scutellum with brown punctures; apex acute, not reach end of coria ( Fig. 67 A View FIGURE 67 ). Coria with all veins concolorous with the surrounding surface ( Fig. 67 A View FIGURE 67 ). Connexival segments without spot and with a pair of concavities ( Fig. 67 A View FIGURE 67 ). Posterolateral angles of connexivum with apices concolorous with the surrounding surface ( Fig. 67 A View FIGURE 67 ). Ventral surface, thorax with black lines; dark line of the propleura covering 2/3 of the width of the sclerite ( Fig. 67 B View FIGURE 67 ). Evaporatorium concolorous with the surrounding surface ( Fig. 67 B View FIGURE 67 ). Metasternal process ( Figs. 40 G View FIGURE 40 ; 67 B View FIGURE 67 ) with arms of anterior bifurcation straight and laterally expanded at apex; anterior bifurcation little excavated receiving fourth and a little less than half of the third rostral segment. Legs with tibiae and tarsi reddish, remaining yellow ( Fig. 67 B View FIGURE 67 ). Abdomen with spine of segment III acuminated ( Fig. 40 G View FIGURE 40 ). Intersegmental areas covered by black lines with well-defined margins, not reaching lateral margin ( Fig. 67 B View FIGURE 67 ). Pseudosutures concolorous with the surrounding surface ( Fig. 67 B View FIGURE 67 , dark lines are a deterioration of the exoskeleton). Median longitudinal brown band incomplete, restricted to the segment VII ( Fig. 67 B View FIGURE 67 ). Trichobothria one in line with spiracle and the other laterad. Posterolateral angles of segment VII not reaching the level of apices of laterotergites IX ( Fig. 40 F View FIGURE 40 ). Male genitalia, dorsal side of the pygophore with a suffused brown area occupying 1/3 of the surface ( Fig. 40 A–B View FIGURE 40 ). Posterolateral angles of the pygophore developed, well projected laterally, apices with spots black ( Fig. 40 A–B, E View FIGURE 40 ). Superior processes of the genital cup rectangular, thick, in flattened and coarse posterior view, continuing ventrally in a crenulate, short and high carina ( Fig. 40 B, F View FIGURE 40 , crenulate carina barely visible). Parameres ( Fig. 40 D–E View FIGURE 40 ) with black margins; anterior lobe subrectangular; dorsal lobe rounded with curved apex; posterior lobe rounded and subrectangular. Proctiger, posterior face subelliptical ( Fig. 40 D–E View FIGURE 40 ). Ventral rim with long setae but without a lateral tuft ( Fig. 40 C View FIGURE 40 ); with expansions undeveloped and concolorous with the surrounding surface ( Fig. 41 C View FIGURE 41 ). Female genitalia, valvifers VIII subrectangular, with dark punctures and a small dentiform projection on the valvifers IX; sutural margins contiguous brown and not divergent; posterior margin brown. Valvifers IX not carinated. Laterotergites VIII with dark band on lateral margins. Laterotergites IX with apices acuminate passing the mediotergite VIII ( Fig. 40 F View FIGURE 40 ).
Comments. Edessa (E.) redunca sp. n. resembles E. (E.) sphaerocornis sp. n., E. (E.) truncatiacantha sp. n., and E. (E.) ventrocarinata sp. n.. These species share reddish antennae; humeral angles black and curved backwards; connexival segments without spot; abdomen ventrally with intersegmental areas black, not reaching lateral margin; dorsal side of the pygophore with a suffused brown area occupying 1/3 of the surface and superior processes of the genital cup with carina. Edessa (E.) redunca sp. n. can be separated from the others mainly by the characteristics of the genitalia.
Distribution ( Fig. 73 View FIGURE 73 ). BRAZIL: Amazonas.
