Edessa (Edessa) fabricii sp. n.

( Figs. 12 , 57 E–F , 72 )

Etymology. Named after Johan Christian Fabricius (1745–1808), Danish entomologist and economist.

Material examined. Holotype male. COLOMBIA: Colombia , 6mi, W. Cali Valle, 1630 m, 20-III-1955, E. I. Schilinger & E. S. Ross coll. ( CAS).

Paratypes. COLOMBIA: 1♀, same data as holotype ( CAS) ; 1♀, Colombia ( NMPC) .

Measurements (n= 3). Total length: 16.4–19.7; head length: 1.5–1.7; head width: 3.0–3.5; pronotum length: 3.3–3.9; pronotum width: 11.0–14.0; scutellum length: 7.6–9.4; scutellum width: 5.5–6.7; abdominal width: 9.0– 9.7; length antennomeres: I: 1.0; II: 1.4–1.5; III: 1.3–2.0; IV: 3.0; V: 4.0.

Diagnosis. Large (16.4–19.7 mm). Dorsal body surface olive green ( Fig. 57 E ). Ventral surface dark yellow to dark reddish brown with transversal black bands on thorax and abdomen; densely punctured ( Fig. 57 F ). Head with brown to concolorous with the surrounding surface punctures. Antennae yellow ( Fig. 57 E–F ). Pronotum densely punctured, with brown punctures ( Fig. 57 E ); anterolateral margin and cicatrices with black punctures. Humeral angles as long as wide; apex with black spot restricted to the angles in dorsal and ventral views; gently curved ( Fig. 57 E–F ). Scutellum with brown punctures; apex not reaching the end of coria ( Fig. 57 E ). Coria with all veins concolorous with the surrounding surface ( Fig. 57 E ). Connexival segments with concavities almost entirely covered by subrectangular black spots separated by a small yellow median spot ( Fig. 57 E ), spots extending ventrally, subrectangular ( Fig. 57 F ). Posterolateral angles of connexivum with apices black ( Fig. 57 E ). Ventral surface, thorax with black bands; dark band of the propleura covering 2/3 of the width of the sclerite ( Fig. 57 F ). Proepisternum coarse, with dark band ( Fig. 57 F ). Evaporatorium black ( Fig. 57 F ). Metasternal process ( Fig. 12 G ) reddish brown, with arms of anterior bifurcation rounded and laterally well expanded at apex; anterior bifurcation little excavated receiving fourth rostral segment. Legs reddish brown ( Fig. 57 F ). Abdomen with spine of segment III rounded ( Figs. 12 G , 57 F ). Intersegmental areas covered by wide black bands with smudged margins, reaching the lateral spots ( Fig. 57 F ). Pseudosutures solid black with well-defined margins ( Fig. 57 F ). Near the spiracle a circular yellow spot ( Fig. 57 F ). Median longitudinal brown band incomplete, restricted to the segment VII ( Fig. 57 F ). Trichobothria one in line with spiracle and the other laterad. Posterolateral angles of segment VII exceeding the level of apices of laterotergites IX ( Fig. 12 F ). Male genitalia, dorsal side of the pygophore with a suffused dark brown area occupying 2/3 of the surface ( Fig. 12 A–B ). Posterolateral angles of the pygophore developed, projected laterally ( Fig. 12 A, C ). Superior processes of the genital cup rectangular, thick, tumid, continuing ventrally in a smooth high carina ( Fig. 12 B, D–E ). Parameres ( Fig. 12 D–E ) with brown margins; anterior lobe inconspicuous and rounded; dorsal lobe rounded; posterior lobe inconspicuous and rounded. Proctiger, posterior face triangular ( Fig. 12 D–E ). Ventral surface densely punctuated; presence of dark spots laterally and medially ( Fig. 12 C ). Ventral rim with lateral subdistal tufts of setae ( Fig. 12 A–C ); with expansions undeveloped and concolorous with the surrounding surface ( Fig. 12 C ). Female genitalia, densely punctured. Valvifers VIII with dark punctures; sutural margins contiguous brown and not divergent; posterior margins in open V-shaped excavation, brown and subrectangular. Laterotergites VIII with a yellow small spot in the middle of the lateral margin surrounded by two larger dark spots. Laterotergites IX with brown spot in the base; with apices rounded passing the mediotergite VIII ( Fig. 12 F ).

Comments. Edessa (E.) fabricii sp. n. resembles E. (E.) flavoantennata sp. n. and E. (E.) reuteri sp. n. by the yellow antennae; black and highly projected humeral angles; coria with all veins concolorous with the surrounding surface; body ventrally with intersegmental areas and pseudosutures black; pygophore with the superior processes of the genital cup carinated; and the female laterotergites VIII with a yellow small spot in the middle of the lateral margin surrounded by two larger dark spots. Edessa (E.) fabricii sp. n. differ from both species by the black evaporatorium (concolorous with the surrounding surface in the other two species); proepisternum with dark band (the other species without band); and the ventral rim of the pygophore with lateral subdistal tufts of setae (the other species without this tufts).

Distribution ( Fig. 72 ). COLOMBIA.
