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 : 48-50

Edessa (Edessa) humeroglobosa sp. n.

( Figs. 21 , 60 E–F , 73 )

Etymology. The name refers to the robust size of the humeral angles (L. humerus, shoulder; L. globus, ball).

Material examined. Holotype male. BRAZIL, Mato Grosso: Aripuan „, 6-IV-1979, A. Soares ( INPA).

Measurements (n= 1). Total length: 18.6; head length: 1.9; head width: 3.5; pronotum length: 4.0; pronotum width: 15.2; scutellum length: 9.1; scutellum width: 7.2; abdominal width: 11.7; length antennomeres: I: 1.0; II: 1.9; III: 2.1; IV: 4.2.

Diagnosis. Large (18.6 mm). Dorsal body surface brown, densely punctured ( Fig. 60 E ). Ventral surface dark yellow to brown with transversal black bands on thorax and abdomen, densely punctured ( Fig. 60 F ). Antennae reddish brown ( Fig. 60 E–F ). Pronotum with brown punctures ( Fig. 60 E ); anterolateral margin and cicatrices with black punctures. Humeral angles short (1.2 times wider than long); apex with brown spot restricted to the angles in dorsal view; slightly bent backward ( Fig. 60 E–F ). Scutellum with concolorous with the surrounding surface punctures; part posterior excavated medially; apex not reaching the end of coria ( Fig. 60 E ). Coria with all veins concolorous with the surrounding surface ( Fig. 60 E ). Connexival segments with concavities almost entirely covered by subrectangular black spots separated by a large yellow median spot ( Fig. 60 E ), spots extending ventrally, subrectangular ( Fig. 60 F ). Posterolateral angles of connexivum with apices black ( Fig. 60 E ). Ventral surface, thorax with black bands; dark band of the propleura covering 2/3 of the width of the sclerite ( Fig. 60 F ). Proepisternum with dark band ( Fig. 60 F ). Evaporatorium concolorous with the surrounding surface; peritreme straight ( Fig. 60 F ). Metasternal process ( Fig. 21 F ) with arms of anterior bifurcation straight and laterally expanded at apex; anterior bifurcation broadly excavated receiving fourth rostral segment. Legs brown ( Fig. 60 F ). Abdomen with spine of segment III rounded ( Fig. 60 F ). Intersegmental areas covered by narrow solid black bands with well-defined margins, reaching the lateral spots ( Fig. 60 F ). Pseudosutures solid black with well-defined margins ( Fig. 60 F ). Median longitudinal brown band incomplete, restricted to the segment VII ( Fig. 60 F ). Trichobothria one in line with spiracle and the other laterad. Male genitalia, posterolateral angles of the pygophore developed, projected laterally, apices internally with spots blacks ( Fig. 21 A–B, D ). Superior processes of the genital cup thick, rectangular, in flattened and coarse posterior view, continuing ventrally in a crenulate high carina ( Fig. 21 B, E crenulate carina barely visible). Parameres ( Fig. 21 D–E ) with black margins; anterior lobe rounded; dorsal lobe subtriangular with little curved apex; posterior lobe subrectangular with curved apex. Proctiger, posterior face subtriangular ( Fig. 21 D–E ). Ventral surface densely punctuated; presence of dark spots laterally and medially ( Fig. 21 C ). Ventral rim with lateral subdistal tuft of setae ( Fig. 21 B–C ); with expansions undeveloped and concolorous with the surrounding surface ( Fig. 21 C ). Female genitalia. Unknown.

Comments. See comments on E. (E.) crassicornis sp. n. and E. (E.) limeirai sp. n.. Edessa (E.) humeroglobosa sp. n. shares with E. (E.) humerorotunda sp. n. and E. (E.) surinamensis sp. n. the proepisternum with dark band and pygophore with superior processes of the genital cup with carina without projection. This species differs from E. (E.) crassicornis sp. n., E. (E.) limeirai sp. n., and E. (E.) surinamensis sp. n. by legs brown (the other species have legs with tibiae and tarsi distinctly reddish) and characteristics of the genitalia.
