( Figs. 27 , 62 E–F , 73 ) Etymology . The name refers to the similarity with E. (E.) lavata Breddin, 1903 (L. indiscretus , closely connected). Material examined. Holotype female. SURINAME : P. H. V. Doesburg Jr. ( RMNH ). Measurements (n= 1). Total length: 20.4; head length: 1.8; head width: 3.6; pronotum length: 3.7; pronotum width: 12.5; scutellum length: 9.5; scutellum width: 7.0; abdominal width: 12.0; length antennomeres: I: 1.0; II: 2.0; III: 1.5; IV: 4.5. Diagnosis. Large ( 20.4 mm ). Dorsal body surface green ( Fig. 62 E ). Ventral surface yellow to orange with transversal black bands on thorax and abdomen ( Fig. 62 F ). Antennae reddish brown ( Fig. 62 E–F ). Pronotum with brown punctures, anterolateral margin with black punctures ( Fig. 62 E ). Humeral angles short (1.3 times wider than long); apex with black spot restricted to the angles in dorsal view and restricted to the margin of the angles in ventral view; bent backward ( Fig. 62 E–F ). Scutellum with brown punctures; posterior part excavated medially; apex not reaching the end of coria ( Fig. 62 E ). Coria with all veins concolorous with the surrounding surface ( Fig. 62 E ). Connexival segments with concavities almost entirely covered by small subrectangular black spots separated by a large yellow median spot ( Fig. 62 E ), spots extending ventrally, triangular ( Fig. 62 F ). Posterolateral angles of connexivum with apices black ( Fig. 62 E ). Ventral surface, thorax with black bands; dark band of the propleura covering 2/3 of the width of the sclerite ( Fig. 62 F ). Evaporatorium concolorous with the surrounding surface ( Fig. 62 F ). Metasternal process ( Fig. 27 B ) with arms of anterior bifurcation straight and laterally expanded at apex; anterior bifurcation slightly excavated receiving half of fourth rostral segment. Legs with tibiae and tarsi slightly reddish, remaining yellow to orange ( Fig. 62 F ). Abdomen with spine of segment III rounded ( Figs. 27 B ; 62 F ). Intersegmental areas covered by narrow solid black bands with well-defined margins, reaching the lateral spots ( Fig. 62 F ). Pseudosutures concolorous with the surrounding surface ( Fig. 62 F , dark lines are a deterioration of the exoskeleton). Median longitudinal brown band incomplete, restricted to the segment VII ( Fig. 62 F ). Trichobothria both parallel to the spiracle. Posterolateral angles of segment VII not reaching the level of apices of laterotergites IX ( Fig. 27 A ). Male genitalia. Unknown. Female genitalia, valvifers VIII with dark punctures; sutural margins contiguous, brown and not divergent; posterior margin brown and arched. Laterotergites VIII with dark band on outer lateral margins. Laterotergites IX with brown spot in the base and apices acuminate passing the mediotergite VIII ( Fig. 27 A ). FIGURE 27. A–B. Edessa (E.) indiscreta sp. n. : A, genital plates; B, metasternal process. Scale= 1 mm. Comments. See comments on E. (E.) brevihumeralis sp. n. and E. (E.) imitans sp. n. . Edessa (E.) indiscreta sp. n. differs from E. (E.) brevihumeralis sp. n. , E. (E.) imitans sp. n. , E. (E.) tenuivittata sp. n. , and E. (E.) lavata (see Mendonça et al. , 2023 , Fig. 11 A–F ) by the characteristics of the genitalia. Distribution ( Fig. 73 ). SURINAME .
