Edessa (Edessa) fuliginocornis sp. n.

( Figs. 17 , 59 C–D , 73 )

Etymology. The name refers to the black humeral angles in dorsal view (L. fuliginosus, sooty; L. cornu).

Material examined. Holotype male. BRAZIL, Pará : Serra Norte Manganês, 24-X-1984, M. F. Torres ( MPEG).

Paratypes. BRAZIL, Pará: 1♀, same data as holotype ( MPEG) ; 1 ♀, Flona Caxiuanã, Melgaço, Base da Estação Científica Ferreira Pena , XI-2003, J. A. M. Fernandes ( UFPA) ; 1 ♀, same data ( INPA) .

Measurements (n= 4). Total length: 18.8–20.9; head length: 1.8; head width: 3.5–3.6; pronotum length: 4.0– 4.2; pronotum width: 13.7–14.4; scutellum length: 8.9–10.0; scutellum width: 6.8–7.3; abdominal width: 10.9–12.2; length antennomeres: I: 1.0; II: 1.4–1.5; III: 1.9–2.0; IV: 4.0.

Diagnosis. Large (18.8–20.9 mm). Dorsal body surface olive green ( Fig. 59 C ). Ventral surface dark yellow to brown with transversal brown bands on thorax and abdomen ( Fig. 59 D ). Antennae reddish brown ( Fig. 59 C ). Pronotum with brown punctures ( Fig. 59 C ); anterolateral margin and cicatrices with brown punctures. Humeral angles as long as wide; apex with black spot restricted to the angles in dorsal view and restricted to the margin in ventral view; slightly bent backward ( Fig. 59 C–D ). Scutellum with brown punctures; apex not reaching the end of coria ( Fig. 59 C ). Coria with all veins yellow ( Fig. 59 C ). Connexival segments with concavities slightly covered by elliptical brown spots ( Fig. 59 C ), spots not extending ventrally ( Fig. 59 D ). Posterolateral angles of connexivum with apices brown ( Fig. 59 C ). Ventral surface, thorax with brown bands; dark band of the propleura covering 1/3 of the width of the sclerite ( Fig. 59 D ). Proepisternum with dark bands ( Fig. 59 D ). Evaporatorium concolorous with the surrounding surface; peritreme straight ( Fig. 59 D ). Metasternal process ( Fig. 17 G ) 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 yellow to brown ( Fig. 59 D ). Abdomen with spine of segment III rounded ( Figs. 17 G ; 59 D ). Intersegmental areas covered by narrow smoky brown bands with smudged margins, not reaching lateral margin ( Fig. 59 D ). Pseudosutures smoky brown with irregular margins ( Fig. 59 D ). Median longitudinal brown band incomplete ( Fig. 59 D ). Trichobothria one in line with spiracle and the other laterad. Posterolateral angles of segment VII exceeding the level of apices of laterotergites IX, almost reaching the level of apices of laterotergites VIII ( Fig. 17 F ). Male genitalia, dorsal side of the pygophore with a suffused dark area occupying 1/3 of the surface ( Fig. 17 A–B ). Posterolateral angles of pygophore slightly developed, narrow ( Fig. 17 A–B ). Superior processes of the genital cup high, rectangular, thick, concave in posterior view, continuing ventrally in a well-developed and thick projection; this projection with truncated apex and thickness does not change until apex ( Fig. 17A–B, E ). Diaphragm with contrasting yellow spot ( Fig. 17 D–E ). Parameres ( Fig. 17 D–E ) with brown margins; anterior lobe well projected, rounded; dorsal lobe subtriangular; posterior lobe rounded. Proctiger, posterior face subelliptical ( Fig. 17 D–E ). Ventral rim with long setae but without a lateral tuft ( Fig. 17 C ); with expansions little developed, rounded, concolorous with the surrounding surface, expansions almost at the same level as the posterolateral angles ( Fig. 17 C ). Female genitalia, valvifers VIII with dark punctures and a rounded and developed projection that projects to the laterotergites IX, a dentiform and small central projection that projects to the valvifers IX; the tumescence with a brown spot; sutural margins contiguous, brown and not divergent; posterior margin brown and forming a deep U-shaped excavation. Valvifers IX not carinated. Laterotergites VIII with brown spot near the spiracle and dark band on outer lateral margins. Laterotergites IX with brown spot in the base, with apices acuminate passing the mediotergite VIII ( Fig. 17 F ).

Comments. See comments on E. (E.) atricornis sp. n.. Edessa (E.) fuliginocornis sp. n. differs from E. (E.) illuminocornis sp. n. and E. (E.) maurocornis sp. n. by the arms of anterior bifurcation the metasternal process receiving only the fourth rostral segment (the other species with the arms of anterior bifurcation the metasternal process receiving the fourth and half of the third rostral segments). The size of the spots of the connexivum and the shape of valvifers VIII are different in E. (E.) fuliginocornis sp. n. and E. (E.) atricornis sp. n., in E. (E.) fuliginocornis the black spots of the connexival segments are larger, the projection of the valvifers VIII is more developed while in E. (E.) atricornis sp. n. the black spots of the connexival segments are smaller and the projection of the valvifers VIII is less developed.

Distribution ( Fig. 73 ). BRAZIL: Pará.
