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 : 90-92

Edessa (Edessa) simulata sp. n.

( Figs. 44 , 68 C–D , 73 )

Etymology. The name refers to the similarity with E. (E.) congrua Walker, 1868 (L. simulatus, imitate, copy).

Material examined. Holotype male. BRAZIL, Pará : Belém, 10-I-1978, H. Estevam ( MPEG).

Measurements (n= 7). Total length: 15.5–17.3; head length: 1.2–1.4; head width: 2.8–2.9; pronotum length: 3.0–3.5; pronotum width: 11.4–12.7; scutellum length: 7.5–8.5; scutellum width: 5.5–6.4; abdominal width: 8.5– 9.0; length antennomeres: I: 0.9–1.0; II: 1.0–1.2; III: 1.5; IV: 3.0–3.1; V: 3.7.

Diagnosis. Large (15.5–17.3 mm). Dorsal body surface green ( Fig. 68 C ). Ventral surface dark yellow to dark brown with transversal black bands on thorax and abdomen ( Fig. 68 D ). Antennae reddish brown ( Fig. 69 C–D ). Pronotum with brown punctures ( Fig. 68 C ); anterolateral margin and cicatrices with brown punctures. Humeral angles short (1.25 times wider than long), projected laterally; apex concolorous with the surrounding surface and not curved ( Fig. 68 C ). Scutellum with brown punctures; apex not reaching the end of coria ( Fig. 68 C ). Coria with all veins concolorous with the surrounding surface ( Fig. 68 C ). Connexival segments with concavities partially covered by circular black spots separated by a large yellow median spot ( Fig. 68 C ), spots extending ventrally, circular ( Fig. 68 D ). Posterolateral angles of connexivum with apices black ( Fig. 68 C ). Ventral surface, thorax with black bands; dark band of the propleura covering 2/3 of the width of the sclerite ( Fig. 68 D ). Evaporatorium concolorous with the surrounding surface ( Fig. 68 D ). Metasternal process ( Figs. 44 G ; 66 D ) with arms of anterior bifurcation straight and laterally expanded at apex; anterior bifurcation broadly excavated receiving fourth rostral segment. Legs with tibiae and tarsi reddish, remaining yellow ( Fig. 68 D ). Abdomen with spine of segment III rounded ( Fig. 44 G ). Intersegmental areas covered by narrow black bands with smudged margins, not reaching the lateral spots ( Fig. 68 D ). Pseudosutures partially covered by black bands ( Fig. 68 D ). Median longitudinal brown band incomplete, restricted to the segment VII ( Fig. 68 D ). Trichobothria one in line with spiracle and the other laterad. Posterolateral angles of segment VII not reaching the level of apices of laterotergites IX ( Fig. 44 F ). Male genitalia, posterolateral angles of pygophore slightly developed, slightly projected laterally ( Fig. 44 A–B ). Superior processes of the genital cup thick, rectangular, flattened and coarse posterior view, continuing ventrally in a crenulate high carina ending in a small dentiform projection ( Fig. 44 B, E , crenulate carina barely visible). Parameres ( Fig. 44 D–E ) with brown margins; anterior lobe little developed, straight and not visible in posterior view; dorsal lobe subtriangular with apex curved; posterior lobe rounded. Proctiger, posterior face subtriangular ( Fig. 44 C–D ). Ventral rim with lateral subdistal tuft of setae; with expansions little developed, rounded, concolorous with the surrounding surface ( Fig. 44 C ). Female genitalia, valvifers VIII subrectangular, with dark punctures and a small dentiform projection on the valvifers IX; sutural margins contiguous, brown and not divergent; posterior margin brown, in open U-shaped excavation. Laterotergites VIII with dark band on outer lateral margins. Laterotergites IX with apices acuminate passing the mediotergite VIII ( Fig. 44 F ).

Comments. See comments on E. (E.) guatemalensis sp. n.. Edessa (E.) simulata sp. n. differs from E. (E.) congrua Walker, 1868 (see Mendonça et al., 2023, Fig. 3 B ) and E. (E.) guatemalensis sp. n. by the pygophore with the superior processes of the genital cup carina with small dentiform projection (the other species without dentiform projection).

Distribution ( Fig. 73 ). BRAZIL: Pará, Goiás.
