(Figs. 32, 64 C–D, 73)
Etymology. The name refers to the black humeral angles in dorsal view (Gr. mauros, dark; L. cornu, horn).
Material examined. Holotype male. BRAZIL, Amazonas: Manaus ZF-2 KM 14 35 m, torre, 09–12-XI-2004, C. S. Motta, A. S. Filho, S. Trovisco, L. S. Aquino (S W 0235215 600655) (INPA).
Measurements (n= 1). Total length: 18.1; head length: 1.9; head width: 3.3; pronotum length: 3.8; pronotum width: 13.2; scutellum length: 8.4; scutellum width: 6.2; abdominal width: 10.6; length antennomeres: I: 1.0; II: 1.2; III: 1.9.
Diagnosis. Large (18.1 mm). Dorsal body surface olive green, densely punctured (Fig. 64 C). Ventral surface yellow with transversal brown bands on thorax and abdomen (Fig. 64 D). Antennae reddish brown (Fig. 64 C). Pronotum with brown punctures (Fig. 64 C); anterolateral margin and cicatrices with brown punctures. Humeral angles as long as wide; laterally directed; apex with black spot restricted to the angles in dorsal view and restricted to the margin of the angles in ventral view, remaining of the spot brown (Fig. 64 C–D). Scutellum with brown punctures; posterior part excavated medially; apex acute not reach end of coria (Fig. 64 C). Coria with all veins yellow (Fig. 64 C). Connexival segments with concavities slightly covered by elliptical brown spots (Fig. 64 C), spots not extending ventrally (Fig. 64 D). Posterolateral angles of connexivum with apices brown (Fig. 64 C).
Ventral surface, thorax with brown bands; dark band of the propleura covering 2/3 of the width of the sclerite (Fig. 64 D). Proepisternum with dark band (Fig. 64 D). Evaporatorium concolorous with the surrounding surface (Fig. 64 D). Metasternal process (Figs. 32 F, 64 D) with arms of anterior bifurcation straight and laterally expanded at apex; anterior bifurcation somewhat excavated receiving fourth of the rostral segment. Legs brown (Fig. 64 D). Abdomen with spine of segment III rounded (Fig. 32 F). Intersegmental areas covered by wide and dark brown to black bands with smudged margins, not reaching lateral margin (Fig. 64 D). Pseudosutures smoky brown to black with irregular margins (Fig. 64 D). Median longitudinal brown band incomplete (Fig. 64 D). Trichobothria one in line with spiracle and the other laterad. Male genital, dorsal side of the pygophore with a suffused dark area occupying 1/3 of the surface (Fig. 32 A–B). Posterolateral angles of pygophore slightly developed, narrow (Fig. 32 A). Superior processes of the genital cup high, rectangular, thick, concave in posterior view and continuing ventrally in a well-developed and thick projection; this projection with truncated apex and thickness does not change until apex (Fig. 32 A–B, C– D). Diaphragm with contrasting yellow spot (Fig. 32 D–E). Parameres (Fig. 32 D–E) with black margins; anterior lobe subrectangular, well projected; dorsal lobe subtriangular; posterior lobe subrectangular. Proctiger, anterior face half black (Fig. 32 D–E); posterior face subelliptical (Fig. 32 D–E). Ventral surface densely punctured, punctures in “V”; with suffused dark spots near the ventral rim, laterally and medially (Fig. 32 C). Ventral rim with long setae but without a lateral tuft (Fig. 32 C); with expansions little developed, rounded, concolorous with the surrounding surface, expansions at the same level as the of posterolateral angles (Fig. 32 C). Female genitalia. Unknown.
Comments. See comments on E. (E.) atricornis sp. n.. Edessa (E.) maurocornis sp. n. differs from E. (E.) atricornis sp. n., E. (E.) fuliginocornis sp. n., and E. (E.) illuminocornis sp. n. by the ventral body bands wide and somewhat vivid (the other species with ventral body bands narrow and faded).
Distribution (Fig. 73). BRAZIL: Amazonas.
