Olbia magnifica. Holotype female. San Francisco de Chipiriri, Bolivia, IV-1953, coll et leg. Antonio Martinez. / Holotype / Olbia magnifica Pirán, 1957. (MACN). Examined by photos (Fig. 52 A–C).

Material examined. BOLIVIA, Cochabamba: 1♁, Chapare 400m, 10-XII-1949, Dirings (Olbia magnifica Pirán, 1958 Fernandes J.A.M. 1999) (MZUSP).

Measurements (n= 1). Total length: 13.1; head length: 2.0; head width: 3.5; pronotum length: 3.8; pronotum width: 16.0; scutellum length: 7.6; scutellum width: 6.5; abdominal width: 9.8; length antennomers: I: 1.0; II: 1.4; III: 2.5; IV: 4.0.

Diagnosis. Large (13.1 mm). Dorsal body surface green (Fig. 52 A–D). Ventral surface yellow to brown with transversal brown lines on thorax and abdomen (Fig. 52 B, E). Antennae reddish brown (Fig. 52 A, D). Pronotum coarse, with concolorous with the surrounding surface to brown punctures; posterior margin with a pair of teeth, between the scutellum (Fig. 52 A, D). Humeral angles very long (2.0 times longer than wide), laterally projected; apex with yellow spot restricted to the angles in dorsal view; leaning forward (Fig. 52 A, D–E). Scutellum with brown punctures; apex not reaching the end of coria (Fig. 52 A, D). Coria reddish, with all veins yellow (Fig. 52 A, D). Connexival segments without spot and with a pair of concavities (Fig. 52 A, D). Posterolateral angles of connexivum with apices brown (Fig. 52 A, D). Ventral surface, thorax with brown lines; dark line of the propleura covering 1/3 of the width of the sclerite (Fig. 52 E). Proepisternum coarse, with dark line (Fig. 52 E). Evaporatorium concolorous with the surrounding surface; peritreme straight (Fig. 52 E). Metasternal process (Fig. 53 F) with arms of anterior bifurcation rounded and laterally barely expanded at apex; anterior bifurcation somewhat excavated receiving fourth rostral segment. Legs with tibiae reddish, remaining yellow (Fig. 52 E). Abdomen with spine of segment III rounded (Fig. 53 F). Intersegmental areas covered by narrow brown lines with smudged margins, not reaching lateral margin (Fig. 52 E). Pseudosutures concolorous with the surrounding surface (Fig. 52 B, E, dark lines are a deterioration of the exoskeleton). Median longitudinal area spotless (Fig. 52 B, E). Trichobothria parallel to the spiracle. Posterolateral angles of segment VII exceeding the level of apices of laterotergites IX (Fig. 52 B). Male genitalia, pygophore wider than long (Fig. 53 A–C). Dorsal side with a suffused brown area occupying 1/3 of the surface (Figs. 53 A–B). Posterolateral angles of pygophore slightly developed, narrow, apices with spot black (Figs. 53 A–B, E). Superior processes of the genital cup subrectangular, thick; flattened, (description continues on page 126) coarse and concave in posterior view, not continuing ventrally in a carina (Fig. 53 B, D–E). Diaphragm setose with contrasting yellow spot (Fig. 53 D–E). Parameres (Fig. 53 D–E) with black margin; anterior lobe rounded, well projected; dorsal lobe and posterior lobe rounded. Proctiger, posterior face triangular (Fig. 53 D–E). Ventral rim without setae (Fig. 53 C); expansions little developed, rounded, brown (Fig. 53 C). Female genitalia, valvifers VIII subrectangular, with dark punctures and setose; sutural margins contiguous, with brown band and not divergent. Laterotergites VIII with dark band on lateral margins. Laterotergites IX with apices acuminate passing the mediotergite VIII (Fig. 52 B).

Comments. Edessa (E.) magnifica is transferred from Olbia to Edessa after verifying the species is very similar to E. (E.) cylindricornis, and shares the diagnostic characteristics of both the subgenus Edessa and the E. sexdens group (Mendonça et al., 2023). Edessa (E.) magnifica and E. (E.) cylindricornis (see Mendonça et al., 2023, Figs. 4 A–E, 25 A) have the posterior pronotal margin with a pair of teeth, the single characteristic used by Stål (1862) to diagnose Olbia, but two cladistic analysis (not published) showed that these teeth probably evolved independently. Edessa (E.) magnifica differs from E. (E.) cylindricornis by the apex of the humeral angles yellow (dark brown in E. (E.) cylindricornis), and characteristics of the male genitalia. The male of Edessa (E.) magnifica (Pirán, 1958) is described here for the first time.
