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 : 43-45

Edessa (Edessa) fulvomaculata sp. n.

( Figs. 18 , 59 E–F , 73 )

Etymology. The name refers to the orange coloration of the central spot of the connexivum segments (L. fulvus, tawny, reddish yellow; L. macula, spot).

Material examined. Holotype male. BRAZIL, Amazonas : Tefé, X-1958, Dirings ( MZUSP).

Paratype. BRAZIL, Amazonas: 1♀, Tefé , IV-1959, Dirings ( MZUSP) .

Measurements (n= 2). Total length: 21.2–23.8; head length: 1.8; head width: 3.8–4.0; pronotum length: 4.3–5.0; pronotum width: 15.0–15.5; scutellum length: 10.4–11,0; scutellum width: 7.7–8.0; abdominal width: 12.4–14.0; length antennomeres: I: 1.0; II: 1.9–2.5; III: 2.0–2.3; IV: 4.8–5.0.

Diagnosis. Large (21.2–23.8 mm). Dorsal body surface reddish brown ( Fig. 59 E ). Ventral surface orange to reddish brown with transversal black lines on thorax and abdomen ( Fig. 59 F ). Antennae reddish brown ( Fig. 59 E–F ). Pronotum with black punctures ( Fig. 59 E ); 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 angles in ventral view; curved backward ( Fig. 59 E–F ). Scutellum with black punctures; posterior part excavated medially; apex not reaching the end of coria ( Fig. 59 E ). Coria with all veins concolorous with the surrounding surface ( Fig. 59 E ). Connexival segments with concavities entirely covered by rectangular black spots separated by a large orange median spot ( Fig. 59 E ), spots extending ventrally, triangular ( Fig. 59 F ). Posterolateral angles of connexivum with apices black ( Fig. 59 E ). Ventral surface, thorax with black lines; dark line of the propleura covering 2/3 of the width of the sclerite ( Fig. 59 F ). Evaporatorium concolorous with the surrounding surface; peritreme straight ( Fig. 59 F ). Metasternal process ( Fig. 18 G ) with arms of anterior bifurcation straight and laterally expanded at apex; anterior bifurcation slightly excavated receiving fourth rostral segment. Legs reddish brown ( Fig. 59 F ). Abdomen with spine of segment III rounded ( Figs. 18 G ; 59 F ). Intersegmental areas covered by narrow brown line with smudged margins, not reaching the lateral spots ( Fig. 59 F ). Pseudosutures concolorous with the surrounding surface ( Fig. 59 F , dark lines are a deterioration of the exoskeleton). Median longitudinal brown band incomplete, restricted to the segment VII ( Fig. 59 F ). Trichobothria both parallel to the spiracle. Posterolateral angles of segment VII not reaching the level of apices of laterotergites IX ( Fig. 18 F ). Male genitalia, dorsal rim of pygophore with margin straight ( Fig. 18 A–B ) Posterolateral angles of pygophore very developed, projected laterally ( Fig. 18 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 develop dentiform projection ( Fig. 18 A–B, E crenulate carina barely visible). Parameres ( Fig. 18 D–E ) with black margins; anterior lobe rounded; dorsal lobe rounded with curved apex; posterior lobe subrectangular. Proctiger, posterior face subelliptical ( Fig. 18 D–E ). Ventral rim with somewhat long setae but without a lateral tuft ( Fig. 18 C ); with expansions little developed, rounded, concolorous with the surrounding surface ( Fig. 18 C ). Female genitalia, valvifers VIII with concolorous with the surrounding surface punctures; sutural margins contiguous, brown, and not divergent; posterior margin in V-shaped excavation, brown and arched. Laterotergites VIII with two dark spots on outer lateral margins. Laterotergites IX with apices rounded passing the mediotergite VIII ( Fig. 18 F ).

Comments. See comments on E. (E.) flaviventris sp. n.. Edessa (E.) fulvomaculata sp. n. differs from E. (E.) flaviventris sp. n., E. (E.) nigrocrocata sp. n., and E. (E.) rutilata sp. n. by the proepisternum without dark line (proepisternum with dark line in the other species).

Distribution ( Fig. 73 ). BRAZIL: Amazonas.
