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 : 94-96

Edessa (Edessa) sphaerocornis sp. n.

( Figs. 46 , 69 A–B , 73 )

Etymology. The name refers to the rounded humeral angles (L. sphaera, ball; L. cornu, horn).

Material examined. Holotype male. PERU, Satipo : Satipo, VIII-1944, P. Paprzyck ( CEIOC).

Paratypes. PERU, Satipo: 1♀, Satipo , IX-1945, P. Paprzyck ( CEIOC) ; 1♀, same local, X-1944, P. Paprzyck ( CEIOC) ; 1♀, same local, VIII-1944, P. Paprzyck ( UFPA) ; 1♁, same local, IX-1944, P. Paprzyck ( UFPA) .

Measurements (n= 5). Total length: 21.7–23.8; head length: 2.0; head width: 3.6–3.8; pronotum length: 4.0–5.0; pronotum width: 15.5–16.8; scutellum length: 10.2–10.9; scutellum width: 7.5–8.4; abdominal width: 12.6–13.5; length antennomeres: I: 1.0; II: 1.9–2.0; III: 2.0–2.5; IV: 4.5–5.2; V: 4.9.

Diagnosis. Large (21.7–23.8 mm). Dorsal body surface green ( Fig. 69 A ). Ventral surface dark yellow to brown with transversal black lines on thorax and abdomen ( Fig. 69 B ). Antennae reddish brown ( Fig. 69 A–B ). Pronotum with black punctures ( Fig. 69 A ); anterolateral margin and cicatrices with brown punctures. Humeral angles short (1.25 times wider than long); apex with black spot expanding over the pronotal disc in dorsal view and restricted to the angles in ventral view; gently bent backward ( Fig. 69 A–B ). Scutellum with black punctures; posterior part excavated medially; apex not reaching the end of coria ( Fig. 69 A ). Coria with veins concolorous with the surrounding surface ( Fig. 69 A ). Connexival segments without spot and with a pair of concavities ( Fig. 69 A ). Posterolateral angles of connexivum with apices concolorous with the surrounding surface ( Fig. 69 A ). Ventral surface, thorax with black lines; dark line of the propleura covering 1/3 of the width of the sclerite ( Fig. 69 B ). Evaporatorium concolorous with the surrounding surface ( Fig. 69 B ). Metasternal process ( Figs. 46 G ; 69 B ) with arms of anterior bifurcation straight and laterally well expanded at apex; anterior bifurcation somewhat excavated receiving fourth and a little less than half of the third rostral segment. Legs reddish brown ( Fig. 69 B ). Abdomen with spine of segment III acuminated ( Figs. 46 G ; 69 B ). Intersegmental areas covered by narrow black lines with well-defined margins, not reaching lateral margin ( Fig. 69 B ). Pseudosutures concolorous with the surrounding surface ( Fig. 69 B , dark lines are a deterioration of the exoskeleton). Near the spiracle a circular brown spot. Median longitudinal brown band incomplete ( Fig. 69 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. 46 F ). Male genitalia, dorsal side of the pygophore with a suffused dark brown area occupying 1/3 of the surface ( Fig. 46 A–B ). Posterolateral angles of the pygophore developed, well projected laterally, apices with spots black ( Fig. 46 A ). Superior processes of the genital cup rectangular, thick, in flattened and coarse posterior view, continuing ventrally in a crenulate high carina ( Fig. 46 B, E , crenulate carina barely visible). Parameres ( Fig. 46 D–E ) with black margins; anterior lobe rounded; dorsal lobe rounded with curved apex; posterior lobe subrectangular. Proctiger, posterior face subelliptical ( Fig. 46 D–E ). Surface ventral, punctures distributed in “V” ( Fig. 46 C ). Ventral rim with long setae but without a lateral tuft ( Fig. 46 C ); with expansions undeveloped and concolorous with the surrounding surface ( Fig. 46 C ). Female genitalia, valvifers VIII with concolorous with the surrounding surface punctures; sutural margins contiguous brown and not divergent; posterior margin brown and slightly arched. Valvifers IX not carinated. Laterotergites VIII with dark band on lateral margins. Laterotergites IX with apices acuminate passing the mediotergite VIII ( Fig. 46 F ).

Comments. See comments on E. (E.) redunca sp. n.. Edessa (E.) sphaerocornis sp. n. differs from E. (E.) redunca sp. n., E. (E.) truncatiacantha sp. n., and E. (E.) ventrocarinata sp. n. by the dark line of the propleura covering 1/3 of the width of the sclerite (the other species with dark line of the propleura covering 2/3 of the width of the sclerite and almost reaching the dark spot of the humeral angles).

Distribution ( Fig. 73 ). PERU: Satipo.
