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 : 35-37

Edessa (Edessa) flaviventris sp. n.

( Figs. 14 , 58 C–D , 72 )

Etymology. The name refers to the yellowish color of the ventral surface of the body (L. flavus, yellow; L. venter, belly).

Material examined. Holotype male. BRAZIL, Amazonas : Uaupés, Rio Negro, 3 -II -1964, Chr. Lindemann ( ZSM).

Measurements (n= 1). Total length: 22.4; head length: 2.3; head width: 3.4; pronotum length: 4.6; pronotum width: 14.7; scutellum length: 10.0; scutellum width: 8.0; abdominal width: 13.3; length antennomeres: I: 1.0; II: 2.0; III: 1.9; IV: 4.5; V: 5.0.

Diagnosis. Large (22.4 mm). Dorsal body surface green, densely punctured ( Fig. 58 C ). Ventral surface dark yellow with transversal black lines on thorax and abdomen ( Fig. 58 D ). Antennae reddish brown ( Fig. 58 C–D ). Pronotum with black punctures ( Fig. 58 C ); anterolateral margin and cicatrices with black punctures. Humeral angles short (1.5 times wider than long); apex with black spot expanding over the pronotal disc in dorsal view and restricted to the margin in ventral view; slightly bent backward ( Fig. 58 C–D ). Scutellum with black punctures; posterior part excavated medially; apex acute, not reach end of coria ( Fig. 58 C ). Coria with veins concolorous with the surrounding surface ( Fig. 58 C ). Connexival segments with concavities entirely covered by rectangular black spots separated by a large yellow median spot ( Fig. 58 C ), spots extending ventrally, triangular ( Fig. 58 D ). Posterolateral angles of connexivum with apices black ( Fig. 58 C ). Ventral surface, thorax with black lines; dark line of the propleura covering 2/3 of the width of the sclerite ( Fig. 58 D ). Proepisternum with dark line ( Fig. 58 D ). Evaporatorium concolorous with the surrounding surface ( Fig. 58 D ). Metasternal process ( Fig. 14 F ) with arms of anterior bifurcation straight and laterally little expanded at apex; anterior bifurcation broadly excavated; rostrum is not in place. Legs brown ( Fig. 58 D ). Abdomen with spine of third segment acuminated ( Fig. 14 F ). Intersegmental areas covered by narrow smoky brown lines with well-defined margins, reaching the lateral spots ( Fig. 58 D ). Pseudosutures concolorous with the surrounding surface ( Fig. 58 D , dark lines are a deterioration of the exoskeleton). Near the spiracle a circular brown spot. Median longitudinal brown band incomplete ( Fig. 58 D ). Trichobothria both parallel to the spiracle. Male genitalia, dorsal side of the pygophore with a suffused reddish brown area occupying 1/3 of the surface ( Fig. 14 A–B ). Posterolateral angles of pygophore very developed, projected laterally ( Fig. 14 A–B ). Superior processes of the genital cup thick, rectangular, in flattened, coarse and concave posterior view, continuing ventrally in a crenulate high carina, ending in a dentiform projection ( Fig. 14 B, E , crenulate carina barely visible). Parameres ( Fig. 14 D–E ) with black margins; anterior lobe inconspicuous and rounded; dorsal lobe rounded; posterior lobe rounded. Proctiger, posterior face subelliptical ( Fig. 14 D–E ). Ventral rim with long setae but without a lateral tuft ( Fig. 14 C ); with expansions undeveloped and concolorous with the surrounding surface ( Fig. 14 C ). Female genitalia. Unknown.

Comments. Edessa (E.) flaviventris sp. n. resembles E. (E.) fulvomaculata sp. n., E. (E.) nigrocrocata sp. n., and E. (E.) rutilata sp. n.. These species share the black, globose, and slightly curved humeral angles; reddish antennae; veins of the coria concolorous with the surrounding surface; connexival segments with rectangular black spot; body ventrally with pseudosutures concolorous with the surrounding surface; and pygophore with the superior processes of the genital cup with crenulate carina. Pygophore with posterolateral angles very developed, well projected laterally are found in E. (E.) flaviventris sp. n., E. (E.) fulvomaculata sp. n., and E. (E.) nigrocrocata sp. n. (less projected laterally in E. (E.) rutilata sp. n.); and the “U”-shaped dorsal rim in E. (E.) flaviventris while straight in the others.

Distribution ( Fig. 72 ). BRAZIL: Amazonas.
