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 : 83-85

Edessa (Edessa) redunca sp. n.

( Figs. 40 , 67 A–B , 73 )

Etymology. The name refers to the humeral angles projected backward (L. reduncus, bent or curved backward).

Material examined. Holotype male. BRAZIL, Amazonas : Tapuruquara, Rio Negro, 20–25-XI-1962, J. Bechyne col. ( MZUSP).

Paratypes. BRAZIL, Amazonas: 1♀ 1♁, Ilha Jerusalem, Rio Negro , 12-V-1964, J. & B. Bechyne ( MPEG) .

Measurements (n= 3). Total length: 21.4–22.4; head length: 1.5–2.5; head width: 3.7–3.8; pronotum length: 4.0–4.5; pronotum width: 13.6–14.8; scutellum length: 10.2–10.6; scutellum width: 7.3–7.8; abdominal width: 11.7–12.2; length antennomeres: I: 1.0; II: 1.5–2.0; III: 2.0; IV: 3.5–3.8; V: 4.0.

Diagnosis. Large (21.4–22.4 mm). Dorsal body surface green, densely punctured ( Fig. 67 A ). Ventral surface dark yellow with transversal black lines on thorax and abdomen ( Fig. 67 C ). Head with brown spot.Antennae reddish brown ( Fig. 67 A–B ). Pronotum coarse, with brown punctures. ( Fig. 67 A ). Humeral angles short (1.3 times wider than long); apex with black spot restricted to the angles in dorsal and ventral views; bent backward ( Fig. 67 A–B ). Scutellum with brown punctures; apex acute, not reach end of coria ( Fig. 67 A ). Coria with all veins concolorous with the surrounding surface ( Fig. 67 A ). Connexival segments without spot and with a pair of concavities ( Fig. 67 A ). Posterolateral angles of connexivum with apices concolorous with the surrounding surface ( Fig. 67 A ). Ventral surface, thorax with black lines; dark line of the propleura covering 2/3 of the width of the sclerite ( Fig. 67 B ). Evaporatorium concolorous with the surrounding surface ( Fig. 67 B ). Metasternal process ( Figs. 40 G ; 67 B ) with arms of anterior bifurcation straight and laterally expanded at apex; anterior bifurcation little excavated receiving fourth and a little less than half of the third rostral segment. Legs with tibiae and tarsi reddish, remaining yellow ( Fig. 67 B ). Abdomen with spine of segment III acuminated ( Fig. 40 G ). Intersegmental areas covered by black lines with well-defined margins, not reaching lateral margin ( Fig. 67 B ). Pseudosutures concolorous with the surrounding surface ( Fig. 67 B , dark lines are a deterioration of the exoskeleton). Median longitudinal brown band incomplete, restricted to the segment VII ( Fig. 67 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. 40 F ). Male genitalia, dorsal side of the pygophore with a suffused brown area occupying 1/3 of the surface ( Fig. 40 A–B ). Posterolateral angles of the pygophore developed, well projected laterally, apices with spots black ( Fig. 40 A–B, E ). Superior processes of the genital cup rectangular, thick, in flattened and coarse posterior view, continuing ventrally in a crenulate, short and high carina ( Fig. 40 B, F , crenulate carina barely visible). Parameres ( Fig. 40 D–E ) with black margins; anterior lobe subrectangular; dorsal lobe rounded with curved apex; posterior lobe rounded and subrectangular. Proctiger, posterior face subelliptical ( Fig. 40 D–E ). Ventral rim with long setae but without a lateral tuft ( Fig. 40 C ); with expansions undeveloped and concolorous with the surrounding surface ( Fig. 41 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. Valvifers IX not carinated. Laterotergites VIII with dark band on lateral margins. Laterotergites IX with apices acuminate passing the mediotergite VIII ( Fig. 40 F ).

Comments. Edessa (E.) redunca sp. n. resembles E. (E.) sphaerocornis sp. n., E. (E.) truncatiacantha sp. n., and E. (E.) ventrocarinata sp. n.. These species share reddish antennae; humeral angles black and curved backwards; connexival segments without spot; abdomen ventrally with intersegmental areas black, not reaching lateral margin; dorsal side of the pygophore with a suffused brown area occupying 1/3 of the surface and superior processes of the genital cup with carina. Edessa (E.) redunca sp. n. can be separated from the others mainly by the characteristics of the genitalia.

Distribution ( Fig. 73 ). BRAZIL: Amazonas.
