Edessa (Edessa) mimica sp. n.

( Figs. 33 View FIGURE 33 , 64 E–F View FIGURE 64 , 73 View FIGURE 73 )

Etymology. The name refers to the similarity with E. (E.) urus Erichson, 1848 (L. mimicus, imitative).

Material examined. Holotype male. VENEZUELA, Mérida: El Vigía, Pan-Americana , Coloncito-Me km 24, 6-I-1955, F. Fernandez Y. & C. J. Rosales ( MPEG).

Measurements (n= 1). Total length: 18.7; head length: 1.8; head width: 3.4; pronotum length: 3.7; pronotum width: 11.8; scutellum length: 8.6; scutellum width: 6.9; abdominal width: 10.6; length antennomeres: I: 1.0; II: 1.5; III: 1.7.

Diagnosis. Large (18.7 mm). Dorsal body surface olive green, densely punctured ( Fig. 64 E View FIGURE 64 ). Ventral surface dark yellow to dark brown with transversal black bands on thorax and abdomen ( Fig. 64 F View FIGURE 64 ). Head with brown punctures and brown spot. Antennae brown ( Fig. 64 E–F View FIGURE 64 ). Pronotum with brown punctures ( Fig. 64 E View FIGURE 64 ); anterolateral margin and cicatrices with brown punctures. Humeral angles very short (2.0 times wider than long); apex concolorous with the surrounding surface and strongly curved backward ( Fig. 64 E View FIGURE 64 ). Scutellum with brown to black punctures; apex at the same level as the end of coria ( Fig. 64 E View FIGURE 64 ). Coria with all veins concolorous with the surrounding surface ( Fig. 64 E View FIGURE 64 ). Connexival segments with concavities almost entirely covered by subrectangular black spots separated by a large yellow median spot ( Fig. 64 E View FIGURE 64 ), spots extending ventrally, subrectangular ( Fig. 64 F View FIGURE 64 ). Posterolateral angles of connexivum with apices black ( Fig. 64 E View FIGURE 64 ). Ventral surface. Thorax with black bands; dark band of the propleura covering 2/3 of the width of the sclerite ( Fig. 64 F View FIGURE 64 ). Proepisternum with dark band ( Fig. 64 F View FIGURE 64 ). Evaporatorium concolorous with the surrounding surface ( Fig. 64 F View FIGURE 64 ). Metasternal process ( Fig. 33 F View FIGURE 33 ) with arms of anterior bifurcation straight and laterally little expanded at apex; anterior bifurcation slightly excavated receiving half of the fourth rostral segment. Legs brown ( Fig. 64 F View FIGURE 64 ). Abdomen with spine of segment III acuminated ( Figs. 33 F View FIGURE 33 ; 64 F View FIGURE 64 ). Intersegmental areas covered by narrow solid black bands with well-defined margins, not reaching the lateral spots ( Fig. 64 F View FIGURE 64 ). Pseudosutures black with well-defined margins ( Fig. 64 F View FIGURE 64 ). Median longitudinal brown band incomplete ( Fig. 64 F View FIGURE 64 ). Trichobothria one in line with spiracle and the other laterad. Male genitalia, dorsal side of the pygophore with a suffused brown area occupying 1/3 of the surface ( Fig. 33 A–B View FIGURE 33 ). Posterolateral angles of the pygophore developed; well projected laterally, apices with spots black ( Fig. 33 A–B, D–E View FIGURE 33 ). Superior processes of the genital cup thick, rectangular, in flattened and coarse posterior view, continuing ventrally in a crenulate and short carina ( Fig. 33 B, D– E View FIGURE 33 , crenulate carina barely visible). Parameres ( Fig. 33 D–E View FIGURE 33 ) with brown margins; anterior lobe subrectangular; dorsal lobe subrectangular, curved apex; posterior lobe triangular. Proctiger, posterior face subelliptical ( Fig. 33 D–E View FIGURE 33 ). Ventral rim not setose ( Fig. 33 C View FIGURE 33 ); with expansions little developed, rounded, concolorous with the surrounding surface ( Fig. 33 C View FIGURE 33 ). Female genitalia. Unknown.

Comments. Edessa (E.) mimica sp. n. resembles E. (E.) urus Erichson, 1848 (see Mendonça et al., 2023, Figs. 23 B View FIGURE 23 , 29 E View FIGURE 29 ) by the shape of the body; short humeral angles (2.0 times wider than long), and concolorous corial veins. On the other hand, both species can be easily separated by the apex of the scutellum level with the end of the coria (in E. (E.) urus apex of scutellum clearly far from the end of coria); pygophore with the superior processes of the genital cup continuing ventrally in a short carina without dentiform projection (in E. (E.) urus continuing ventrally in a high carina ending in a small dentiform projection).
