Measurements (n= 4). Total length: 15.4–16.9; head length: 1.1–1.9; head width: 3.0–3.1; pronotum length: 3.2–3.3; pronotum width: 10.5–10.7; scutellum length: 7.4–7.7; scutellum width: 5.8–6.0; abdominal width: 8.9– 9.1; length antennomeres: I: 0.8–1.0; II: 1.4–1.5; III: 1.5; IV: 3.0–3.6; V: 3.5.

Diagnosis. Large ( 15.4–16.9 mm). Dorsal body surface olive green, densely punctured ( Fig. 66 E ). Ventral surface dark yellow to reddish brown with transversal black bands on thorax and abdomen ( Fig. 66 F ). Head with black punctures. Antennae yellow ( Fig. 66 E–F ). Pronotum with brown punctures ( Fig. 66 E ); anterolateral margin and cicatrices with black punctures. Humeral angles short (1.5 times wider than long); apex with black spot restricted to the angles in dorsal and ventral views; bent backward ( Fig. 66 E ). Scutellum with black to brown punctures; posterior part excavated medially; apex at the same level as the end of coria ( Fig. 66 E ). Coria with all veins concolorous with the surrounding surface ( Fig. 66 E ). Connexival segments with concavities entirely covered by rectangular black spots separated by a large yellow median spot ( Fig. 66 E ), spots extending ventrally, subrectangular ( Fig. 66 F ). Posterolateral angles of connexivum with apices black ( Fig. 66 E ). Ventral surface, thorax with black bands; dark band of the propleura covering 2/3 of the width of the sclerite ( Fig. 66 F ). Proepisternum with dark band ( Fig. 66 F ). Evaporatorium concolorous with the surrounding surface ( Fig. 66 F ). Metasternal process ( Figs. 39 G ; 66 F ) with arms of anterior bifurcation straight and laterally well expanded at apex; anterior bifurcation broadly excavated receiving fourth rostral segment. Legs with tibiae and tarsi reddish, remaining dark yellow ( Fig. 66 F ). Abdomen with spine of segment III rounded ( Figs. 39 G ; 66 F ). Intersegmental areas covered by narrow black bands with smudged margins, reaching the lateral spots ( Fig. 66 F ). Pseudosutures solid black with smudged margins ( Fig. 66 F ). Median longitudinal black band incomplete ( Fig. 66 F ). 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. 39 F ). Male genitalia, dorsal side of the pygophore with a suffused brown area occupying 2/3 of the surface ( Fig. 39 A–B ). Posterolateral angles of the pygophore developed; well projected laterally, apices with spots black ( Fig. 39 A–B, D ). Superior processes of the genital cup rectangular, thick, in flattened and coarse posterior view, continuing ventrally in a crenulate, long and high carina ( Fig. 39 B, E crenulate carina barely visible). Parameres ( Fig. 39 D–E ) with brown margins; anterior lobe subrectangular; dorsal lobe rounded, with strongly curved apex; posterior lobe subrectangular. Proctiger, posterior face subtriangular ( Fig. 39 D–E ). Surface ventral with dark spots laterally and medially ( Fig. 39 C ). Ventral rim setose, with medial tuft ( Fig. 39 A–C ); with expansions little developed, rounded and black ( Fig. 39 C ). Female genitalia, valvifers VIII with dark punctures; sutural margins contiguous brown and not divergent; posterior margin in open V-shaped excavation, brown and slightly arched. Valvifers IX not carinated, large. Laterotergites VIII with two dark spots on lateral and a large yellow spot in middle of the margins. Laterotergites IX with apices acuminate passing the mediotergite VIII ( Fig. 39 F ).

Comments. Edessa (E.) pseudonigroangulata sp. n. resembles E. (E.) nigroangulata Fernandes & Silva, 2015 (see description in Fernandes et al., 2015 and images in Mendonça et al., 2023, Figs. 17 A–C , 28 E–F ), both species share: antennae yellow; coria with all veins concolorous with the surrounding surface; ventrally abdomen with intersegmental areas black; and ventral rim of the pygophore with lateral subdistal tuft of setae. On the other hand, both species can be easily separated by: anterolateral margin of the pronotum coarse, crenulate and emarginated in E. (E.) nigroangulata (in E. (E.) pseudonigroangulata sp. n. anterolateral margin smooth and not emarginated); width of the humeral angles (wider in E. (E.) nigroangulata ); color of the legs (in E. (E.) pseudonigroangulata sp. n. legs with tibiae and tarsi more red than the other articles, all articles yellow in E. (E.) nigroangulata ); connexival segments with rectangular spots ( E. (E.) nigroangulata with trapezoidal spots); ventrally abdomen with pseudosutures black ( E. (E.) nigroangulata with pseudosutures brown); dorsal side of the pygophore with a suffused brown area occupying 2/3 of the surface ( E. (E.) nigroangulata with dorsal side of the pygophore without suffused brown area); and superior processes of the genital cup with high carina ( E. (E.) nigroangulata with low carina).
