Edessa (Edessa) chloroicterica sp. n.

( Figs. 7 View FIGURE 7 , 56 A–B View FIGURE 56 , 73 View FIGURE 73 )

Etymology. The name refers to the body green and yellow (Gr. chloros, green; Gr. ikteros, yellow).

Material examined. Holotype male. BRAZIL, Rondônia: Rio Jacundá , IX-1963, E. H. Bon ( RMNH).

Paratype. BRAZIL, Rondônia 1♀, same data as holotype, X-1963 ( RMNH) .

Measurements (n= 2). Total length: 19.0–19.5; head length: 2.0; head width: 3.1–3.3; pronotum length: 3.8– 4.1; pronotum width: 13.0–14.2; scutellum length: 8.7–9.5; scutellum width: 6.6–7.2; abdominal width: 10.8–11.7; length antennomeres: I: 1.0; II: 2.0; III: 1.6; IV: 4.0; V: 4.5.

Diagnosis. Large (19.0– 19.5 mm). Dorsal body surface green ( Fig. 56 A View FIGURE 56 ). Ventral surface dark yellow to green with transversal dark green bands on thorax and abdomen ( Fig. 56 B View FIGURE 56 ). Antennae with first to third segments reddish brown, remaining brown ( Fig. 56 A–B View FIGURE 56 ). Pronotum with brown punctures ( Fig. 56 A View FIGURE 56 ). Humeral angles as long as wide, laterally directed; apex with black spot restricted to the angles in dorsal and ventral views ( Fig. 56 A–B View FIGURE 56 ). Scutellum with brown punctures; apex not reaching the end of coria ( Fig. 56 A View FIGURE 56 ). Coria with all veins concolorous with the surrounding surface ( Fig. 56 A View FIGURE 56 ). Connexival segments with concavities entirely covered by rectangular green spots separated by a large yellow median spot; green spots extending ventrally connected with green bands of the abdomen ( Fig. 56 B View FIGURE 56 ). Posterolateral angles of connexivum with apices green. Ventral surface, thorax with green bands; band of the propleura almost reaching the green spot of the humeral angles ( Fig. 56 B View FIGURE 56 ). Evaporatorium concolorous with the surrounding surface; peritreme straight ( Fig. 56 B View FIGURE 56 ). Metasternal process ( Fig. 7 G View FIGURE 7 ) with arms of anterior bifurcation rounded and laterally barely expanded at apex; anterior bifurcation somewhat excavated receiving fourth and part of the third rostral segment. Legs reddish brown ( Fig. 56 B View FIGURE 56 ). Abdomen with spine of segment III acuminated ( Fig. 56 B View FIGURE 56 ). Intersegmental areas covered by narrow brown line with adjacent smudged green band, reaching the lateral spots ( Fig. 56 B View FIGURE 56 ). Pseudosutures concolorous with the surrounding surface ( Fig. 56 B View FIGURE 56 , dark lines are a deterioration of the exoskeleton). Median longitudinal brown band incomplete, restricted to the segment VII ( Fig. 56 B View FIGURE 56 ). Trichobothria both in line with the spiracle. Posterolateral angles of segment VII exceeding the level of laterotergites IX ( Fig. 7 F View FIGURE 7 ). Male genitalia, dorsal side of the pygophore with a smudged dark brown area occupying half of the surface ( Fig. 7 A–B View FIGURE 7 ). Posterolateral angles of pygophore barely developed ( Fig. 7 A–B View FIGURE 7 ). Superior processes of the genital cup rectangular, narrow and continuing ventrally in a well-developed, digitiform and narrow projection ( Fig. 7 A–B, E View FIGURE 7 ). Diaphragm with contrasting yellow spot ( Fig. 7 B, D–E View FIGURE 7 ). Parameres ( Fig. 7 D–E View FIGURE 7 ) with black margin; anterior lobe rounded; dorsal lobe subtriangular and rounded, curved toward posterolateral angles; posterior lobe narrow and rounded. Proctiger, anterior half black ( Fig. 7 A–B, D–E View FIGURE 7 ); posterior face triangular ( Fig. 7 D–E View FIGURE 7 ). Ventral rim sparsely setose ( Fig. 7 C View FIGURE 7 ); with expansions developed, rounded, concolorous with the surrounding surface, expansions exceed the apices of posterolateral angles ( Fig. 7 C View FIGURE 7 ). Female genitalia, valvifers VIII with brown punctures; distally with small brown spot; sutural margins contiguous; posterior margin arched, medially with shallow U-shaped excavation. Laterotergites VIII with two dark spots on outer lateral margins. Laterotergites IX with apices acuminate slightly exceeding the mediotergite VIII ( Fig. 7 F View FIGURE 7 ).

Comments. Edessa (E.) chloroicterica sp. n. resembles E. (E.) flavofemorata sp. n., E. (E.) nigroantennata sp. n., E. (E.) rufofusca sp. n., E. (E.) tuberculata sp. n., E. (E.) viridifasciata sp. n., and E. (E.) imbecilla Breddin, 1903 (see Mendonça et al., 2023, Fig. 9 A–B View FIGURE 9 ). They are dorsally green grass and ventrally yellow with green bands; connexival segments with green spots extending ventrally; antennae with first segment clearer and remaining dark and arms of anterior bifurcation the metasternal process with apices rounded. The species E. (E.) chloroicterica sp. n. shares with E. (E.) rufofusca sp. n. the coloration of the body, antennae with first to third segments reddish brown, remaining brown; humeral angles slightly curved and robust. But E. (E.) chloroicterica sp. n. differs from E. (E.) rufofusca sp. n. by the second antennal segment longer than the third (second antennal segment shorter than the third in E. (E.) rufofusca sp. n.); anterolateral margin of pronotum more curved, slightly angulose and humeral angles longer (anterolateral margin gently curved and humeral angles shorter in E. (E.) rufofusca sp. n.). Other species differ from E. (E.) chloroicterica sp. n. by the black color of the antennal segments, except the first.
