Edessa (Edessa) tuberculata sp. n.

( Figs. 49 , 70 A–B , 73 )

Etymology. The name refers to the shape of the humeral angles (L. tuberculum dim. tuber, swelling).

Material examined. Holotype male. COLOMBIA, Amazonas : Aval de la Chorrera 30 km, Rio Igara-Parana, 15-II-1974, J. Desplats rec., MNHN ( EH) 25717 ( MNHN).

Measurements (n= 1). Total length: 16.6; head length: 1.7; head width: 2.9; pronotum length: 3.3; pronotum width: 11.0; scutellum length: 8.2; scutellum width: 5.9; abdominal width: 10.0; length antennomeres: I: 1.0; II: 1.5; III: 1.5; IV: 4.0.

Diagnosis. Large (16.6 mm). Dorsal body surface green ( Fig. 70 A ). Ventral surface dark yellow to green with transversal green bands on thorax and abdomen ( Fig. 70 B ). Antennae with first brown segment and second to fifth black segment ( Fig. 70 A–B ). Pronotum with concolorous with the surrounding surface punctures ( Fig. 70 A ); anterolateral margin with a yellow band extending from the humeral angles to the head. Humeral angles short (1.25 times wider than long), narrow; apex concolorous with the surrounding surface and strongly curved backward ( Fig. 70 A–B ). Scutellum with concolorous with the surrounding surface punctures; posterior part excavated medially; apex large, not reach end of coria ( Fig. 70 A ). Coria with all veins concolorous with the surrounding surface ( Fig. 70 A ). Connexival segments with concavities entirely covered by rectangular green spots separated by a large yellow median spot ( Fig. 70 A ), spots extending ventrally and green spot forming green bands on the abdomen ( Fig. 70 B ). Posterolateral angles of connexivum with apices green ( Fig. 70 A ). Ventral surface, thorax with green bands; dark band of the propleura connected to the spot of the humeral angles ( Fig. 70 B ). Evaporatorium concolorous with the surrounding surface; peritreme straight ( Fig. 70 B ). Metasternal process ( Fig. 49 F ) with arms of anterior bifurcation rounded and laterally barely expanded at apex; anterior bifurcation somewhat excavated. Legs reddish brown ( Fig. 70 A–B ). Abdomen with spine of segment III rounded ( Figs. 49 F ; 70 B ). Intersegmental areas covered by brown line with adjacent smudged green bands, reaching the lateral spots ( Fig. 70 B ). Pseudosutures concolorous with the surrounding surface ( Fig. 70 B ). Median longitudinal brown band incomplete ( Fig. 70 B ). Trichobothria both parallel to the spiracle. Male genitalia, dorsal side of the pygophore with a suffused dark area occupying 2/3 of the surface ( Fig. 49 A–B ). Dorsal rim setose ( Fig. 70 A ). Posterolateral angles of pygophore slightly developed, apices with spot black ( Fig. 49 A–B, D ). 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. 49 B, E ). Parameres ( Fig. 49 D–E ) with brown margins; anterior lobe rounded, near to diaphragm; dorsal lobe subtriangular, curved toward posterolateral angles; posterior lobe subrectangular. Proctiger, anterior half black; posterior face triangular ( Fig. 49 D–E ). Ventral surface densely punctured, punctures distributed in posterior half ( Fig. 49 C ). Ventral rim with long setae but without a lateral tuft ( Fig. 49 C ); with expansions little developed, rounded, concolorous with the surrounding surface, expansions level with posterolateral angles ( Fig. 49 C ). Female genitalia. Unknown.

Comments. See comments on E. (E.) chloroicterica sp. n.. Edessa (E.) tuberculata sp. n. differs from E. (E.) chloroicterica sp. n., E. (E.) flavofemorata sp. n., E. (E.) imbecilla (see Mendonça et al., 2023, Fig. 9 C–E ), E. (E.) nigroantennata sp. n., E. (E.) rufofusca sp. n., E. (E.) tuberculata sp. n., and Edessa (E.) viridifasciata sp. n. by the characteristics of the genitalia.
