Edessa (Edessa) glomerosa sp. n.

( Figs. 19 , 60 A–B , 72 )

Etymology. The name refers to the shape of the humeral angles (L. glomerosus, like a ball, round).

Material examined. Holotype male. PERU, Satipo : Satipo, XI-1943, P. Paprzyck ( CEIOC).

Paratypes. PERU, Satipo: 1♁, Satipo , 16-VII-1937, P. Paprzyck ( CEIOC); 1♀ , same data, III-1944 ( CEIOC) .

Measurements (n= 3). Total length: 21.8–23.1; head length: 2.0; head width: 2.8–3.5; pronotum length: 4.2–4.8; pronotum width: 13.3–15.8; scutellum length: 10.1–10.9; scutellum width: 7.5–7.7; abdominal width: 12.5–13.9; length antennomeres: I: 1.0; II: 1.9–2.0; III: 2.0–2.4; IV: 4.3–5.0.

Diagnosis. Large (21.8–23.1 mm). Dorsal body surface brownish olive ( Fig. 60 A ). Ventral surface dark yellow to greenish with transversal black bands on thorax and abdomen ( Fig. 60 B ). Mandibular plates deeply furrowed ( Fig. 60 A ). Antennae reddish brown ( Fig. 60 A–B ). Pronotum densely punctured, with brown punctures ( Fig. 60 A ); anterolateral margin and cicatrices with brown punctures. Humeral angles short (1.2 times wider than long); apex with black spot expanding slightly over the pronotal disc in dorsal view and restricted to the angles in ventral view; curved backward ( Fig. 60 A–B ). Scutellum with brown punctures; posterior part excavated medially; apex not reaching the end of coria ( Fig. 60 A ). Coria with concolorous with the surrounding surface ( Fig. 60 A ). Connexival segments with concavities entirely covered by rectangular black spots separated by a large yellow median spot ( Fig. 60 A ), spots extending ventrally, triangular ( Fig. 60 B ). Posterolateral angles of connexivum with apices black ( Fig. 60 A ). Ventral surface, thorax with black bands; dark band of the propleura covering 2/3 of the width of the sclerite ( Fig. 60 B ). Evaporatorium concolorous with the surrounding surface; peritreme straight ( Fig. 60 B ). Metasternal process ( Fig. 19 G ) with arms of anterior bifurcation straight and laterally well expanded at apex; anterior bifurcation slightly excavated receiving fourth rostral segment. Legs with tibiae and tarsi reddish, remaining yellow (not clearly visible on Fig. 60 B ). Abdomen with spine of segment III rounded ( Figs. 19 G ; 60 B ). Intersegmental areas covered by solid black bands with well-defined margins, reaching the lateral spots ( Fig. 60 B ). Pseudosutures concolorous with the surrounding surface ( Fig. 60 B , dark lines are a deterioration of the exoskeleton). Near the spiracle there is a circular brown spot. Median longitudinal brown band incomplete, restricted to the segment VII ( Fig. 60 B ). Trichobothria both parallel to the spiracle. Posterolateral angles of segment VII not exceeding the level of apices of laterotergites IX ( Fig. 19 F ). Male genitalia, dorsal side of the pygophore with a suffused brown area occupying 1/3 of the surface ( Fig. 19A–B ). Posterolateral angles of pygophore very developed, projected laterally, apices with spots blacks ( Fig. 19 A–C ). Superior processes of the genital cup narrow, triangular, continuing ventrally in a smooth high carina ( Fig. 19 B, E ). Parameres ( Fig. 19 D–E ) with brown margins; anterior lobe inconspicuous and straight; dorsal lobe subtriangular and rounded, with curved apex; posterior lobe subtriangular. Proctiger, posterior face triangular ( Fig. 19 D–E ). Surface ventral with a suffused brown area occupying 2/3 of the surface ( Fig. 19 C ). Ventral rim with lateral subdistal tuft of setae; with expansions little developed, rounded and brown ( Fig. 19 B–C ). Female genitalia, valvifers VIII with concolorous with the surrounding surface punctures; sutural margins contiguous, brown and not divergent; posterior margin in V-shaped excavation, brown and slightly arched. Laterotergites VIII with two dark spots on outer lateral margins. Laterotergites IX with apices acuminate passing the mediotergite VIII ( Fig. 19 F ).
