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 : 12-14

Edessa (Edessa) amapaensis sp. n.

( Figs. 2 , 54 C–D , 72 )

Etymology. The name is a tribute to the State of Amapá where the specimen was collected.

Material examined. Holotype male. BRAZIL, Amapá: Rio Amapari , 25-V-1966, S. Mario ( MPEG).

Measurements (n= 1). Total length: 20.9; head length: 1.7; head width: 3.5; pronotum length: 4.4; pronotum width: 15.1; scutellum length: 10.1; scutellum width: 7.7; abdominal width: 12.7; length antennomeres: I: 1.0; II: 2.2; III: 2.2; IV: 5.0.

Diagnosis. Large (20.9 mm). Dorsal body surface green ( Fig. 54 C ). Ventral surface dark yellow to brown with transversal black bands on thorax and abdomen ( Fig. 54 D ). Margins of the clypeus with black punctures ( Fig. 54 C ). Antennae reddish brown ( Fig. 54 C–D ). Pronotum with black punctures ( Fig. 54 C ); anterolateral margins and cicatrices with black punctures. Humeral angles short (1.7 times wider than long); apex with black spot expanding over the pronotal disc in dorsal view and restricted to the angles in ventral view; slightly curved backward ( Fig. 54 C–D ). Scutellum with black punctures; posterior part excavated medially; apex acute, not reaching the apex of coria ( Fig. 54 C ). Coria with all veins concolorous with the surrounding surface ( Fig. 54 C ). Connexival segments with concavities entirely covered by subrectangular black spots separated by a large yellow median spot ( Fig. 54 C ); black spots extending ventrally, triangular ( Fig. 54 D ). Posterolateral angles of connexivum with apex black ( Fig. 54 C ). Ventral surface, thorax with black bands; dark band of propleura connected to dark spot of humeral angles ( Fig. 54 D ). Evaporatorium concolorous with the surrounding surface; peritreme straight ( Fig. 54 D ). Metasternal process ( Fig. 2 F ) with arms of anterior bifurcation straight and little expanded laterally at apex; anterior bifurcation somewhat excavated receiving the fourth rostral segment. Legs with tibiae and tarsi reddish, remaining yellow. Abdomen with spine of segment III rounded ( Figs. 2 F ; 54 D ). Intersegmental areas covered by narrow black bands with smudged margins, reaching the lateral spots ( Fig. 54 D ). Pseudosutures partially covered by light brown lines ( Fig. 54 D ). Median longitudinal brown band incomplete, restricted to the segment VII ( Fig. 54 D ). Trichobothria both in line with the spiracle. Male genitalia, dorsal side of the pygophore with narrow brown band ( Fig. 2 A–B ). Posterolateral angles of pygophore very developed, projected laterally ( Fig. 2 A,C ); apices with black spot ( Fig. 2 A–B ). Superior processes of the genital cup rectangular, thick, flattened distally and coarse in posterior view, continuing ventrally in a crenulate high carina, ending in a small dentiform projection ( Fig. 2 B, D–E , carina barely visible). Parameres ( Fig. 2 A–E ) with brown margins; anterior lobe subtriangular; dorsal lobe subtriangular with laterally bent apex; somewhat developed subtriangular posterior lobe; anterior face with carina. Proctiger, posterior face subelliptical ( Fig. 2 D–E ). Ventral rim with long setae but without a lateral tuft ( Fig. 2 C ), with expansions undeveloped and concolorous with the surrounding surface ( Fig. 2 C ). Ventral surface with black spots, laterally transverse and medially longitudinal ( Fig. 2 C ). Female genitalia. Unknown.

Comments. Edessa (E.) amapaensis sp. n. resembles E. (E.) amaurata sp. n., both share reddish brown antennae; black and curved humeral angles; pygophore with the superior processes of the genital cup carinated with dentiform projection, and anterior face of the paramere carinated. On the other hand, both species can be easily separated by the coria with all veins concolorous with the surrounding surface in E. amapaensis sp. n. ( E. amaurata sp. n. with veins greenish yellow); by a large yellow median spot in the connexivum ( E. amaurata sp. n. have a black spot and three very small yellow calloused areas); intersegmental areas with smudged bands and reaching the lateral black spots ( E. amaurata sp. n. with solid bands and not reaching the lateral spots).

Distribution ( Fig. 72 ). BRAZIL: Amapá.
