Edessa (Edessa) maculosa sp. n.

( Figs. 30 , 63 E–F , 72 )

Etymology. The name refers to the dark spot of the connexival segments (L. macula, spot).

Material examined. Holotype male. BRAZIL, Rondônia: Forte Príncipe da Beira , 19-XI–3-XII-1967, G. R. Kloss coll. ( MZUSP)

Paratype. BRAZIL, Rondônia: 1♀, Forte Príncipe da Beira , 19-XI–3-XII-1967, G. R. Kloss coll. ( MZUSP) .

Measurements (n= 2). Total length: 20.3–21.2; head length: 1.6; head width: 3.5–3.6; pronotum length: 4.0– 4.1; pronotum width: 13.9–14.5; scutellum length: 9.6–10.1; scutellum width: 7.3–7.5; abdominal width: 11.6–13.0; length antennomeres: I: 1.0; II: 1.5–2.0; III: 1.9–2.0; IV: 4.8; V: 5,1.

Diagnosis. Large (20.3–21.2 mm). Dorsal body surface green ( Fig. 63 E ). Ventral surface dark yellow to brown with transversal brown lines on thorax and abdomen ( Fig. 63 F ). Antennae reddish brown ( Fig. 63 E–F ). Pronotum coarse, with concolorous with the surrounding surface punctures ( Fig. 63 E ). Humeral angles short (1.4 times wider than long); apex with black spot restricted to the angles in dorsal view and restricted to the margin of the angles in ventral view; bent backward ( Fig. 63 E–F ). Scutellum with concolorous with the surrounding surface punctures; apex not reaching the end of coria ( Fig. 63 E ). Coria with all veins concolorous with the surrounding surface ( Fig. 63 E ). Connexival segments with concavities almost entirely covered by subrectangular black spots separated by a large yellow median spot ( Fig. 63 E ), spots extending ventrally, subrectangular ( Fig. 63 F ). Posterolateral angles of connexivum with apices black ( Fig. 63 E ). Ventral surface, thorax with brown lines; dark line of the propleura covering 2/3 of the width of the sclerite ( Fig. 63 F ). Evaporatorium concolorous with the surrounding surface; peritreme straight ( Fig. 63 F ). Metasternal process ( Fig. 30 G ) with arms of anterior bifurcation straight and laterally expanded at apex; anterior bifurcation broadly excavated receiving fourth and a small part of the third rostral segment. Legs brown ( Fig. 63 F ). Abdomen with spine of third segment rounded ( Fig. 30 G ). Intersegmental areas covered by narrow brown lines with smudged margins, not reaching the lateral spots ( Fig. 30 G ). Pseudosutures light brown with well-defined margins ( Fig. 63 F ). Median longitudinal area spotless ( Fig. 63 F ). Trichobothria both parallel to the spiracle. Posterolateral angles of segment VII exceeding the level of apices of laterotergites IX, almost reaching the level of apices of laterotergites VIII ( Fig. 30 F ). Male genitalia, dorsal rim with margin straight ( Fig. 30 A ). Posterolateral angles of pygophore slightly developed, slightly projected laterally, apices internally with spots black ( Fig. 30 A–B ). Superior processes of the genital cup rectangular, thick, in flattened and coarse posterior view, continuing ventrally in a crenulate, short and high carina, ending in a small dentiform projection ( Fig. 30 B, D–E , crenulate carina barely visible). Parameres ( Fig. 30 D–E ) with black margins; anterior lobe more developed and subrectangular; dorsal lobe rounded with very curved apex; posterior lobe subrectangular. Proctiger, posterior face subelliptical ( Fig. 30 D–E ). Ventral rim not setose ( Fig. 30 C ); with expansions undeveloped and concolorous with the surrounding surface ( Fig. 30 C ). Female genitalia, valvifers VIII cordiform, with concolorous with the surrounding surface punctures; sutural margins contiguous brown and not divergent; posterior margin in open Vshaped excavation and brown. Laterotergites VIII with dark band on lateral margins. Laterotergites IX with apices slightly acuminate passing the mediotergite VIII ( Fig. 30 F ).

Comments. See comments on E. (E.) inca sp. n.. Edessa (E.) maculosa sp. n. differs from E. (E.) inca and E. (E.) electa Walker, 1868 (see Mendonça et al., 2023, Fig. 5 B–F ) by the pygophore with superior processes of the genital cup with a short carina (long carina in the others) and laterotergites VIII with dark band on outer lateral margins (two dark spots on outer lateral margins in the others).

Distribution ( Fig. 72 ). BRAZIL: Rondônia.
