description: Edessa (Edessa) accola sp. n.
(Figures 1, 54 A–B, 72)
Etymology. This name refers to the similarity with E. (E.) fallenii Stål, 1872 (L. accola, neighbor).
Material examined. Holotype male. BRAZIL, Rio de Janeiro: Rio de Janeiro (CMNH).
Measurements (n= 1). Total length: 16.4; head length: 1.4; head width: 3.2; pronotum length: 3.8; pronotum width: 11.3; scutellum length: 8.2; scutellum width: 6.6; abdominal width: 10.1; length antennomeres: I: 0.9; II: 1.3; III: 1.6; IV: 3.5; V: 4.0.
Diagnosis. Large (16.4 mm). Dorsal body surface green (Fig. 54 A). Ventral surface dark reddish brown with transversal smudged reddish band on thorax and abdomen (Fig. 54 B). Antennae brown (Fig. 54A–B). Pronotum with concolorous with the surrounding surface punctures (Fig. 54 A). Humeral angles short (1.6 times wider than long); apex with light brown spot restricted to the angles in dorsal view, ventrally without spot; slightly bent posteriorly (Fig. 54 A–B). Scutellum with concolorous with the surrounding surface punctures; apex not reaching the end of the coria (Fig. 54 A). Coria with all veins concolorous with the surrounding surface (Fig. 54 A). Connexival segments without spot, with a pair of concavities (Fig. 54 A). Posterolateral angles of connexivum with apices concolorous with the surrounding surface (Fig. 54 A). Ventral surface, thorax with dark band of propleura covering 2/3 of the width of the sclerite (Fig. 54 B). Evaporatorium concolorous with the surrounding surface; peritreme straight (Fig. 54 B). Metasternal process (Fig. 1 F) with arms of anterior bifurcation straight and well expanded laterally at apex; anterior bifurcation broadly excavated receiving the fourth and a small part of the third rostral segment. Legs with tibiae and tarsi darker than the other articles (Fig. 54 B). Abdomen with spine of segment III rounded (Fig. 1 F). Intersegmental areas covered by wide smoky reddish band with smudged margins, reaching the lateral margin (Fig. 54 B). Pseudosutures smoky brown with irregular margins (Fig. 54 B). Median longitudinal brown band almost complete and suffused (Fig. 54 B). Trichobothria one in line with spiracle and the other laterad. Male genitalia, dorsal side of the pygophore with suffused brown area occupying more than 1/3 of the surface (Fig. 1 A–B). Posterolateral angles of pygophore slightly developed (Fig. 1 A). Superior processes of the genital cup rectangular, narrow, grooved in posterior view, not continuing ventrally in a carina (Fig. 1 B, D–E). Parameres (Fig. 1 D–E) concolorous with the surrounding surface; anterior lobe subtriangular and somewhat developed; dorsal lobe rounded, developed and curved; posterior lobe subtriangular and developed. Proctiger, posterior face subelliptical (Fig. 1 D–E). Ventral rim setose, with medial tuft (Fig. 1 C); with expansions little developed, rounded, concolorous with the surrounding surface (Fig. 1 C). Female genitalia. Unknown.
Comments. Edessa (E.) accola sp. n. resembles E. (E.) fallenii Stål, 1872 (see Mendonça et al., 2023, Figs. 6A–G, 25 E–F) as it has the humeral angles light brown or concolorous with the pronotal surface; segments of the connexivum without spots and pygophore with the posterior face of the proctiger elliptical. On the other hand, both species can be easily separated: E. (E.) accola sp. n. has the connexivum with concavities on each segment (connexivum without concavities in E. (E.) fallenii); abdomen ventrally with intersegmental areas smoky reddish and pseudosutures smoky brown (intersegmental areas and pseudosutures black in E. (E.) fallenii) and pygophore with the superior processes of the genital cup without carina (superior processes of the genital cup carinated in E. (E.) fallenii).
Distribution (Fig. 72). BRAZIL: Rio de Janeiro.
