Edessa (Edessa) infuscata sp. n.

(Figs. 28, 63 A–B, 74)

Etymology. The name refers to the dark dorsal color of the body (L. in, on; L. infuscus, dark brown).

Material examined. Holotype male. FRENCH GUIANA: Roura on Kaw Rd. 33km, 1–2-VI-2005, J. E. Eger & M. T. Messenger coll. (04º34.135’ N 05º11.150’ W) (USNM).

Paratypes. SURINAME, Brokopondo: 1♀, Brownsberg Nature Park 450-480m, 10-XII-1971, G. F. Mees (RMNH) ; FRENCH GUIANA: 1♁, 1899, R. Oberthur, MNHN (EH) 25718 (MNHN).

Measurements (n= 3). Total length: 19.7–22.3; head length: 1.4–1.8; head width: 3.6–3.8; pronotum length: 4.1–4.5; pronotum width: 14.5–16.1; scutellum length: 9.5–10.5; scutellum width: 7.1–8.0; abdominal width: 11.2– 13.3; length antennomeres: I: 1.0; II: 1.9–2.0; III: 1.9–2.5; IV: 5.0.

Diagnosis. Large (19.7–22.3 mm). Dorsal body surface brown (Fig. 63 A). Ventral surface dark yellow to orange with transversal black bands on thorax and abdomen (Fig. 63 B). Antennae reddish brown (Fig. 63 A–B). Pronotum with black punctures (Fig. 63 A), anterolateral margin and cicatrices with black punctures; in the region of cicatrices yellow callosity (Fig. 63 A). Humeral angles as long as wide; apex with black spot expanding over the pronotal disc in dorsal view and restricted to the angles in ventral view; curved backward (Fig. 63 A–B). Scutellum with black punctures; apex not reaching the end of coria (Fig. 63 A). Coria with all veins yellow (Fig. 63 A). Connexival segments with concavities almost entirely covered by elliptical brown spots (Fig. 63 A), spots not extending ventrally (Fig. 63 B). Posterolateral angles of connexivum with apices brown (Fig. 63 A). Ventral surface, thorax with black bands; dark band of the propleura almost reaching the dark spot of the humeral angles (Fig. 63 B). Evaporatorium concolorous with the surrounding surface (Fig. 63 B). Metasternal process (Figs. 28 G; 63 B) with arms of anterior bifurcation straight and laterally expanded at apex; anterior bifurcation somewhat excavated receiving fourth and a small part of the third rostral segment. Legs with tibiae and tarsi reddish, remaining orange (Fig. 63 B). Abdomen with spine of segment III rounded (Figs. 28 G; 63 B). Intersegmental areas covered by narrow black bands with smudged margins, not reaching lateral margin (Fig. 63 B). Pseudosutures concolorous with the surrounding surface (Fig. 63 B, dark lines are a deterioration of the exoskeleton). Median longitudinal brown band incomplete (Fig. 63 B). Trichobothria both parallel to the spiracle. Posterolateral angles of segment VII exceeding the level of apices of laterotergites IX (Fig. 28 F). Male genitalia, posterolateral angles of the pygophore developed, projected laterally (Fig. 28 A). Superior processes of the genital cup rectangular, thick, flattened and coarse in posterior view, continuing ventrally in a smooth high carina, ending in a dentiform and narrow projection developed (Fig. 28 B, D–E). Parameres (Fig. 28 D–E) with black margins; anterior lobe triangular; dorsal lobe small, triangular; posterior lobe triangular. Proctiger, posterior face subelliptical (Fig. 28 D–E). Diaphragm reddish (Fig. 28 D–E). Ventral rim with lateral subdistal tuft of setae (Fig. 28 C–E); with expansions undeveloped and concolorous with the surrounding surface (Fig. 28 C). Female genitalia, valvifers VIII subrectangular, concolorous with the surrounding surface punctures and a small dentiform projection that projects to the valvifers IX; sutural margins contiguous brown and not divergent; posterior margin in open U-shaped excavation, brown and straight. Laterotergites VIII with dark band on lateral margins. Laterotergites IX with apices acuminate passing the mediotergite VIII (Fig. 28 F).

Comments. Edessa (E.) infuscata sp. n. resembles E. (E.) maranhensis sp. n. by the humeral angles black; spots of the connexival segments not extending ventrally and intersegmental areas of the abdomen ventrally black, not reaching lateral margin. On the other hand, both species can be easily separated by the subelliptical spots of the connexival segments (subrectangular in E. (E.) maranhensis sp. n.); coria with all veins yellow (concolorous in E. (E.) maranhensis sp. n.); pygophore with superior processes of the genital cup carina with dentiform projection (without dentiform projection in E. (E.) maranhensis sp. n.) and ventral rim with lateral subdistal tuft of setae (without such tuft in E. (E.) maranhensis sp. n.).
