Treatment

Edessa (Edessa) cornicula sp. n.

( Figs. 8 View FIGURE 8 , 56 C–D View FIGURE 56 , 73 View FIGURE 73 )

Etymology. The name refers to the size and development of the humeral angles (L. cornu, horn; cornicula , dim).

Material examined. Holotype female. PERU, Loreto: Estiron, Rio Ampiacu , 15–22-V-1966, Malkin leg. ( MZUSP).

Measurements (n= 1). Total length: 22.3; head length: 1.5; head width: 3.5; pronotum length: 4.5; pronotum width: 14.2; scutellum length: 10.3; scutellum width: 7.5; abdominal width: 12.8; length antennomeres: I: 1.5; II: 2.0; III: 2.3; IV: 4.8.

Diagnosis. Large (22.3 mm). Dorsal body surface olive green ( Fig. 56 C View FIGURE 56 ). Ventral surface dark yellow to brown with transversal brown bands on thorax and abdomen ( Fig. 56 D View FIGURE 56 ). Antennae yellowish ( Fig. 56 C–D View FIGURE 56 ). Pronotum with brown punctures ( Fig. 56 C View FIGURE 56 ); anterolateral margin with a yellow band extending from the humeral angles to the head; anterolateral margin and cicatrices with brown punctures. Humeral angles very short (2.0 times wider than long); apex concolorous with the surrounding surface, slightly acuminate and curved backwards ( Fig. 56 C View FIGURE 56 ). Scutellum with brown punctures; apex not reaching the end of coria ( Fig. 56 C View FIGURE 56 ). Coria with all veins concolorous with the surrounding surface ( Fig. 56 C View FIGURE 56 ). Connexival segments with concavities entirely covered by subrectangular black spots separated by a large dark yellow median spot ( Fig. 56 C View FIGURE 56 ); black spots extending ventrally, subrectangular ( Fig. 56 D View FIGURE 56 ). Posterolateral angles of connexivum with apices black ( Fig. 56 C View FIGURE 56 ). Ventral surface, thorax with brown bands; dark band of the propleura covering 2/3 of the width of the sclerite ( Fig. 56 D View FIGURE 56 ). Evaporatorium concolorous with the surrounding surface; peritreme straight ( Fig. 56 D View FIGURE 56 ). Metasternal process ( Fig. 8 B View FIGURE 8 ) with arms of anterior bifurcation straight, laterally well expanded at apex; anterior bifurcation broadly excavated receiving fourth rostral segment. Legs yellowish ( Fig. 56 D View FIGURE 56 ). Abdomen with spine of segment III rounded ( Figs. 8 B View FIGURE 8 ; 56 D View FIGURE 56 ). Intersegmental areas covered by narrow smudged brown bands with well-defined margins, reaching the lateral spots ( Fig. 56 D View FIGURE 56 ). Pseudosutures concolorous with the surrounding surface ( Fig. 56 D View FIGURE 56 ). Median longitudinal area spotless ( Fig. 56 D View FIGURE 56 ). Trichobothria both parallel to the spiracle. Posterolateral angles of segment VII exceeding the level of apices of laterotergites IX ( Fig. 8 A View FIGURE 8 ). Male genitalia. Unknown. Female genitalia, valvifers VIII with concolorous with the surrounding surface punctures; sutural margins contiguous; posterior margin subrectangular with small and shallow U-shaped excavation delimited by small rounded projections. Laterotergites VIII without dark band. Laterotergites IX with apices acuminate and level with mediotergite VIII ( Fig. 8 A View FIGURE 8 ).

Comments. Edessa (E.) cornicula sp. n. resembles Edessa (E.) urus Erichson, 1848 (see Mendonça et al., 2023, Figs. 23 F View FIGURE 23 , 29 E–F View FIGURE 29 ). Both species share the humeral angles concolorous with the surrounding surface, short and curved; body ventrally with intersegmental areas brown. Both species can be separated by characteristics of the genitalia, in E. (E.) cornicula sp. n. the posterior margin of the valvifers VIII is subrectangular and apices of the laterotergites IX level with mediotergite VIII, while in E. (E.) urus the posterior margin of the valvifers VIII is clearly arched and the apices of the laterotergites IX passing the mediotergite VIII.

Distribution ( Fig. 73 View FIGURE 73 ). PERU: Loreto.
