Edessa (Edessa) nigroantennata sp. n.

Etymology. The name refers to the black antennae (L. nigro, black; L. antenna).

Measurements (n= 3). Total length: 17.8–20.2; head length: 1.6–2,7; head width: 3.2–3,5; pronotum length: 3.8–4,5; pronotum width: 11.1–12,1; scutellum length: 7.5–9,2; scutellum width: 6.3–7,0; abdominal width: 10.9– 11,8; length antennomeres: I: 1.0; II: 1,8–2.0; III: 2,0–2.2; IV: 3,8–4.5; V: 5.0–5,5.

Diagnosis. Large (17.8–20.2 mm). Dorsal body surface green, densely punctured ( Fig. 65 C ). Ventral surface dark yellow to green with transversal green bands on thorax and abdomen ( Fig. 65 D ). Antennae with first segment brown and second to fifth segment black ( Fig. 65 C–D ). Pronotum with concolorous with the surrounding surface punctures ( Fig. 65 C ); anterolateral margin with a yellow band that extends from the humeral angles to the head. Humeral angles very short (2.0 times wider than long), narrow; apex concolorous with the surrounding surface; strongly bent backward ( Fig. 65 C–D ). Scutellum with concolorous with the surrounding surface punctures; apex rounded, not reach end of coria ( Fig. 65 C ). Coria with all veins concolorous with the surrounding surface ( Fig. 65 C ). Connexival segments with concavities entirely covered by rectangular green spots separated by a large yellow median spot ( Fig. 65 C ), spots extending ventrally and green spot forming green bands on the abdomen ( Fig. 65 D ). Posterolateral angles of connexivum with apices green ( Fig. 65 C ). Ventral surface, thorax with green bands; green band of the propleura connected to the humeral angles ( Fig. 65 D ). Evaporatorium concolorous with the surrounding surface; peritreme straight ( Fig. 65 D ). Metasternal process ( Figs. 35 G ; 65 D ) with arms of anterior bifurcation rounded and laterally barely expanded at apex; anterior bifurcation somewhat excavated receiving fourth and more than half of the third rostral segment. Legs brown ( Fig. 65 D ). Abdomen with spine of segment III rounded. Intersegmental areas covered by narrow brown line with adjacent smudged green band, reaching the lateral spots ( Fig. 65 D ). Pseudosutures concolorous with the surrounding surface ( Fig. 65 D ). Median longitudinal brown band incomplete, restricted to the segment VII ( Fig. 65 D ). Trichobothria both parallel to the spiracle. Posterolateral angles of segment VII exceeding the level of apices of laterotergites IX, almost reaching the level of apices of laterotergites VIII ( Fig. 35 F ). Male genitalia, dorsal side of the pygophore with suffused dark area occupying 2/3 of the surface ( Fig. 35 A–B ). Posterolateral angles of pygophore slightly developed, narrow ( Fig. 35 A–B ). Superior processes of the genital cup rectangular, narrow, higher than the projection and continuing ventrally in a well-developed and narrow projection; this projection with apex extended and truncated ( Fig. 35 A–B, E ). Parameres ( Fig. 35 D–E ) with light brown margins; anterior lobe rounded; dorsal lobe subtriangular, curved toward superior processes of the genital cup; posterior lobe subrectangular. Proctiger, posterior face subtriangular ( Fig. 35 D–E ). Ventral rim with long setae but without a lateral tuft ( Fig. 35 C ); with expansions developed, rounded, concolorous with the surrounding surface, expansions surpassing the level of posterolateral angles ( Fig. 35 C ). Female genitalia, valvifers VIII with concolorous with the surrounding surface punctures; medially near the sutural margins with a brown spot, contiguous and not divergent; posterior margin arched and forming a U-shaped excavation. Laterotergites VIII with two dark spots on lateral margins. Laterotergites IX with apices roudend at the same level as the mediotergite VIII ( Fig. 35 F ).

Comments. See comments on E. (E.) chloroicterica sp. n. and E. (E.) flavofemorata sp. n.. Edessa (E.) nigroantennata sp. n. has scutellum with apex rounded like E. (E.) imbecilla Breddin, 1903 (see Mendonça et al., 2023, Fig. 9 A ) (scutellum with apex acute in E. (E.) chloroicterica sp. n., E. (E.) flavofemorata sp. n., E. (E.) tuberculata sp. n., and E. (E.) viridifasciata sp. n.). This species can be separated from the others by characteristics of the genitalia.
