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 : 55-57

Edessa (Edessa) immaculata sp. n.

( Figs. 25 , 62 A–B , 74 )

Etymology. The name refers to the absence of dark spots on the connexivum (L. in, not, without; L. macula, spot).

Material examined. Holotype male. BRAZIL, Pará : Ponta de Pedras, 3-III-1979, P. Tadeu ( MPEG).

Paratype. BRAZIL, Pará: 1♀, Óbidos, ( Edessa close sexdens sp. n. —V. J. Silva 2017 det.) ( MPEG).

Measurements (n= 2). Total length: 16.4–17.3; head length: 1.6–1.7; head width: 3.0–3.2; pronotum length: 3.3–3.6; pronotum width: 10.3–11.3; scutellum length: 7.7; scutellum width: 6.4–6.6; abdominal width: 8.4–9.8; length antennomeres: I: 0.9–1.0; II: 1.3; III: 1.2–1.5; IV: 3.3–5.0.

Diagnosis. Large (16.4–17.3 mm). Dorsal body surface olive green ( Fig. 62 A ). Ventral surface dark yellow to brown with transversal black bands on thorax and abdomen ( Fig. 62 B ). Antennae reddish brown ( Fig. 62 A–B ). Pronotum with brown punctures ( Fig. 62 A ); anterolateral margin and cicatrices with black punctures. Humeral angles short (1.2 times wide than longer); apex with black spot expanding slightly over the pronotal disc in dorsal view and expanding slightly over the propleura in ventral view; bent backward ( Fig. 62 A–B ). Scutellum with brown punctures; apex not reaching the end of coria ( Fig. 62 A ). Coria with all veins concolorous with the surrounding surface ( Fig. 62 A ). Connexival segments without spots and with a pair of concavities concolorous with the surrounding surface ( Fig. 62 A ). Posterolateral angles of connexivum with apices concolorous with the surrounding surface ( Fig. 62 A ). Ventral surface, thorax with black bands; dark band of the propleura covering 2/3 of the width of the sclerite ( Fig. 62 B ). Proepisternum, densely punctured, with dark band ( Fig. 62 B ). Evaporatorium concolorous with the surrounding surface ( Fig. 62 B ). Metasternal process ( Fig. 25 G ) with arms of anterior bifurcation rounded and laterally barely expanded at apex; anterior bifurcation somewhat excavated receiving half of fourth rostral segment. Legs brown ( Fig. 62 B ). Abdomen with spine of segment III acuminated ( Figs. 25 G ; 62 B ). Intersegmental areas covered by narrow solid black bands with well-defined margins, not reaching lateral margin ( Fig. 62 B ). Pseudosutures brown with well-defined margins ( Fig. 62 B ). Median longitudinal brown band incomplete ( Fig. 62 B ). 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. 25 F ). Male genitalia, dorsal side of the pygophore with a suffused brown area occupying 1/3 of the surface ( Fig. 25 A–B ). Posterolateral angles of pygophore slightly developed, slightly projected laterally, apices with spots blacks ( Fig. 25 A–B, D–E ). Superior processes of the genital cup rectangular, thick, in flattened and coarse posterior view, continuing ventrally in a crenulate high carina ending in a dentiform projection ( Fig. 25 B, D , crenulate carina barely visible). Parameres ( Fig. 25 D–E ) with black margins; anterior lobe rounded; dorsal lobe subrectangular, apex curved; posterior lobe subrectangular. Proctiger, posterior face subelliptical ( Fig. 25 D–E ). Ventral surface with suffused dark spots laterally and medially ( Fig. 25 C ). Ventral rim with long setae but without a lateral tuft ( Fig. 25 C ); with expansions undeveloped and concolorous with the surrounding surface ( Fig. 25 C ). Female genitalia, valvifers VIII with dark punctures, subrectangular; sutural margins contiguous and not divergent; posterior margin straight. Valvifers IX not carinated. Laterotergites VIII with light brown band on lateral margins. Laterotergites IX with brown spot in the base and apices acuminate passing the mediotergite VIII ( Fig. 25 F ).

Comments. See comments on E. (E.) decolorata sp. n.. Edessa (E.) immaculata sp. n. differs from E. (E.) decolorata sp. n. and E. (E.) nigriclava Walker, 1868 (see Mendonça et al., 2023, Figs. 15 B , 28 A–B ) by the connexivum with concavities (the other species with connexivum flat); ventrally abdomen with pseudosutures brown ( E. (E.) decolorata sp. n. with pseudosutures concolorous with the surrounding surface and E. (E.) nigriclava with pseudosutures black) and pygophore with the superior processes of the genital cup with carina with dentiform projection (the other species without dentiform projection).

Distribution ( Fig. 74 ). BRAZIL: Pará.
