Edessa (Edessa) chloroicterica sp. n.

( Figs. 7 , 56 A–B , 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 ). Ventral surface dark yellow to green with transversal dark green bands on thorax and abdomen ( Fig. 56 B ). Antennae with first to third segments reddish brown, remaining brown ( Fig. 56 A–B ). Pronotum with brown punctures ( Fig. 56 A ). 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 ). Scutellum with brown punctures; apex not reaching the end of coria ( Fig. 56 A ). Coria with all veins concolorous with the surrounding surface ( Fig. 56 A ). 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 ). 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 ). Evaporatorium concolorous with the surrounding surface; peritreme straight ( Fig. 56 B ). Metasternal process ( Fig. 7 G ) 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 ). Abdomen with spine of segment III acuminated ( Fig. 56 B ). Intersegmental areas covered by narrow brown line with adjacent smudged green band, reaching the lateral spots ( Fig. 56 B ). Pseudosutures concolorous with the surrounding surface ( Fig. 56 B , dark lines are a deterioration of the exoskeleton). Median longitudinal brown band incomplete, restricted to the segment VII ( Fig. 56 B ). Trichobothria both in line with the spiracle. Posterolateral angles of segment VII exceeding the level of laterotergites IX ( Fig. 7 F ). Male genitalia, dorsal side of the pygophore with a smudged dark brown area occupying half of the surface ( Fig. 7 A–B ). Posterolateral angles of pygophore barely developed ( Fig. 7 A–B ). Superior processes of the genital cup rectangular, narrow and continuing ventrally in a well-developed, digitiform and narrow projection ( Fig. 7 A–B, E ). Diaphragm with contrasting yellow spot ( Fig. 7 B, D–E ). Parameres ( Fig. 7 D–E ) 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 ); posterior face triangular ( Fig. 7 D–E ). Ventral rim sparsely setose ( Fig. 7 C ); with expansions developed, rounded, concolorous with the surrounding surface, expansions exceed the apices of posterolateral angles ( Fig. 7 C ). 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 ).

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 ). 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.
