Campos, Breno Batista, Nunes, Benedito Mendes, Bitar, Murilo Victor Silva & Fernandes, Jose Antonio Marin, 2020, Description of a new group of species of Edessa Fabricius, 1803 (Hemiptera: Pentatomidae: Edessinae) with translucent spot on hemelytra, Zootaxa 4810 (1), pp. 131-142 : 134-136

Edessa translucida sp. n.

( Figs. 2 A–D; 5C–D; 6)

Etymology. This name refers to the translucent part of corium (From latin. Trans: across, through; Lucida: full of light).

Holotype male. PANAMA: Coll. R. I. Sc. N. B ( IRSN).

Material examined. Paratype female. same data holotype ( IRSN) .

Measurements. antennomeres length: 1st: 0.7; 2nd: 1.6–1.9; 3rd: 1.2–1.3; 4th: 2.4–2.5; 5th: 2.3; head length: 1.3; head width: 2.2–2.4; pronotal length: 2.2–2.5; pronotal width: 6.6–7.3; scutellum length: 4.9–5.5; scutellum width: 3.8–4.2; abdominal width: 6.3–7.0; total length: 12.3–13.4.

Diagnosis. Antennal segment I smoky black dorsally, green ventrally ( Fig. 5C,D ); other segments smoky black with basal yellow ring on segments III and IV, segment V with basal third yellow; segment II longer than segment III. Anterolateral margins of pronotum yellow ( Fig. 5C ). Costal margins of coria yellow on basal third ( Fig. 5C ). Corial punctures adjacent to each claval suture black, concolorous on remainder of coria ( Fig. 5C ). Coria each with faint smoky brown spot restricted to area with black punctures ( Fig. 5C ). Pygophore with dorsal rim ending in an indentation close to each posterolateral angle, those clearly above level of posterolateral angles ( Fig. 2A ). Gonocoxites 8 strongly convex, lateral angles barely projected and acute ( Fig. 2D ).

Description. Head. Apices of mandibular plates green or smoky black.

Thorax. Humeral angles yellow on apical margins ( Fig. 5C ). Scutellum with apex impunctate and margin black ( Fig. 5C ). Veins of coria concolorous with corial surfaces ( Fig. 5C ). Membranes of hemelytra light brown ( Fig. 5C ). Ventral surface punctation sparse, shallow, light brown ( Fig. 5D ).

Abdomen. Distal margins of seventh abdominal segments black ( Fig. 5C ).

Male ( Fig. 2 A–C). Dorsal rim of pygophore only slightly projected, with a pair of submedian brown concretions ( Fig. 2A ); concolorous with dorsal surface, except thin, brown ridge between concretions. Posterolateral angles somewhat posteriorly projected and rounded; tumescence almost imperceptible ( Fig. 2A ). Superior process of the genital cup dark brown, rounded, and small. Parameres flattened; each anterior lobe large, dorsally directed, fanshaped, slightly concave; posterior lobe clavate, strongly curved laterodorsally; margins brown ( Fig. 2B ). Proctiger with lateral excavations deep, dorsally delimited by short keel; posterior face large, subtriangular ( Fig. 2B ). Ventral rim with a medial deep excavation delimited by small, acuminated, concave expansions, not reaching level of lateral angles in ventral view ( Fig. 2C ). Ventral surface rugulose, sparsely punctured.

Female ( Fig. 2D ). Gonocoxites 8 slightly projected posteriorly, not reaching middle of laterotergites 9; mesial borders slightly divergent distally, forming a tiny tooth. Gonocoxites 9 slightly inclined laterally. Laterotergites 9 each with base deeply excavated, with a fingerlike tumescence contiguous to each gonocoxite 8; apices clearly surpassing sclerite uniting laterotergites 8.
