Mendonça, Maria Thayane Da Silva, Silva, Valéria Juliete Da & Fernandes, José Antônio Marin, 2023, Description of fifty-one new species and new taxonomic arrangement for the E. sexdens group of the subgenus Edessa (Heteroptera, Pentatomidae, Edessinae, Edessa), Zootaxa 5372 (1), pp. 1-128 : 70-72

Edessa (Edessa) mimica sp. n.

( Figs. 33 , 64 E–F , 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 ). Ventral surface dark yellow to dark brown with transversal black bands on thorax and abdomen ( Fig. 64 F ). Head with brown punctures and brown spot. Antennae brown ( Fig. 64 E–F ). Pronotum with brown punctures ( Fig. 64 E ); 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 ). Scutellum with brown to black punctures; apex at the same level as the end of coria ( Fig. 64 E ). Coria with all veins concolorous with the surrounding surface ( Fig. 64 E ). Connexival segments with concavities almost entirely covered by subrectangular black spots separated by a large yellow median spot ( Fig. 64 E ), spots extending ventrally, subrectangular ( Fig. 64 F ). Posterolateral angles of connexivum with apices black ( Fig. 64 E ). Ventral surface. Thorax with black bands; dark band of the propleura covering 2/3 of the width of the sclerite ( Fig. 64 F ). Proepisternum with dark band ( Fig. 64 F ). Evaporatorium concolorous with the surrounding surface ( Fig. 64 F ). Metasternal process ( Fig. 33 F ) 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 ). Abdomen with spine of segment III acuminated ( Figs. 33 F ; 64 F ). Intersegmental areas covered by narrow solid black bands with well-defined margins, not reaching the lateral spots ( Fig. 64 F ). Pseudosutures black with well-defined margins ( Fig. 64 F ). Median longitudinal brown band incomplete ( Fig. 64 F ). 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 ). Posterolateral angles of the pygophore developed; well projected laterally, apices with spots black ( Fig. 33 A–B, D–E ). 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 , crenulate carina barely visible). Parameres ( Fig. 33 D–E ) with brown margins; anterior lobe subrectangular; dorsal lobe subrectangular, curved apex; posterior lobe triangular. Proctiger, posterior face subelliptical ( Fig. 33 D–E ). Ventral rim not setose ( Fig. 33 C ); with expansions little developed, rounded, concolorous with the surrounding surface ( Fig. 33 C ). Female genitalia. Unknown.

Comments. Edessa (E.) mimica sp. n. resembles E. (E.) urus Erichson, 1848 (see Mendonça et al., 2023, Figs. 23 B , 29 E ) 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).
