(Figs. 39, 66 E–F, 74)
Etymology. The name refers to the similarity with E. (E.) nigroangulata Fernandes & Silva, 2015.
Material examined. Holotype male. COSTA RICA, Puntarenas: 1♁, Estacion Sirena, 1-100m, 20–27-III-1995, A. Azoifeifa (L N 270500 507900), # 5286, INBIO CRI002 205358 (INBIO).
Paratypes. COSTA RICA, Puntarenas: 1♀, Rancho Quemado, 200m, 4–28-VI-1994, A. Marin (L N 292500 511000), # 3013, INBIO CRI001 885901 (INBIO); 1♀, Corcovado National Park, 21–30-IX-1977, D. H. Jenzen coll., INBIO CRI001 686751 (INBIO); 1♀, Sirena, Corcovado National Park, 13–22-III-1980, D. H. Jenzen coll., CRI001 715426 (UFPA).
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).
