description: Edessa (Edessa) ventrocarinata sp. n.
(Figs. 50, 70 C–D, 72)
Etymology. The name refers to the high ventral median carina of the abdomen (L. venter, belly; L. carina, keel).
Material examined. Holotype male. BRAZIL, Minas Gerais: Mesquita, 19-IV-1977, J. P. Martins col. (MZUSP).
Measurements (n= 1). Total length: 20.1; head length: 1.8; head width: 3.5; pronotum length: 3.8; pronotum width: 13.7; scutellum length: 9.6; scutellum width: 7.0; abdominal width: 11.2; length antennomeres: I: 1.0; II: 1.3; III: 2.0; IV: 4.3.
Diagnosis. Large (20.1 mm). Dorsal body surface green, densely punctured (Fig. 70 C). Ventral surface dark yellow to reddish, with transversal black lines on thorax and abdomen (Fig. 70 D). Head with brown punctures. Antennae reddish brown (Fig. 70 C–D). Pronotum with brown punctures (Fig. 70 C); anterolateral margin and cicatrices with brown punctures; anterolateral margin coarse. Humeral angles short (1.3 times wider than long); apex black spot restricted to the angles in dorsal view and restricted to the margin of the angles in ventral view; slightly bent backward (Fig. 70 C–D). Scutellum with brown punctures; apex not reaching the end of coria (Fig. 70 C). Coria with all veins concolorous with the surrounding surface (Fig. 70 C). Connexival segments without spot and with a pair of concavities (Fig. 70 C). Posterolateral angles of connexivum with apices concolorous with the surrounding surface (Fig. 70 C). Ventral surface, thorax with black lines; dark line of the propleura covering 2/3 of the width of the sclerite (Fig. 70 D). Proepisternum densely punctured, coarse (Fig. 70 D). Evaporatorium concolorous with the surrounding surface; peritreme straight (Fig. 70 D). Metasternal process (Figs. 50 F, 70 D) with arms of anterior bifurcation straight and laterally well expanded at apex; anterior bifurcation broadly excavated receiving fourth and a small part of the third rostral segment. Legs brown (Fig. 70 D). Abdomen with spine of segment III acuminated (Fig. 50 F). Intersegmental areas covered by narrow black lines with well-defined margins, not reaching lateral margin (Fig. 70 D). Pseudosutures brown with well-defined margins (Fig. 70 D). Median longitudinal brown band incomplete, restricted to the segment VII (Fig. 70 D). Trichobothria one in line with spiracle and the other laterad. Male genitalia, dorsal side of the pygophore with a suffused brown area occupying 1/3 of the surface (Fig. 50 A–B). Posterolateral angles of the pygophore developed, projected laterally, apices with spot black (Fig. 50 A–B). Superior processes of the genital cup rectangular, thick, in flattened, coarse and sinuous posterior view, continuing ventrally in a smooth, short and high carina (Fig. 50 B, E carina little visible). Parameres (Fig. 50 D–E) with black margins; anterior lobe rounded; dorsal lobe subtriangular with curved apex; posterior lobe subtriangular. Proctiger, posterior face subelliptical (Fig. 50 D–E). Ventral rim with long setae but without a lateral tuft (Fig. 50 C); with expansions undeveloped and concolorous with the surrounding surface (Fig. 50 C). Female genitalia. Unknown.
Comments. See comments on E. (E.) redunca sp. n.. Edessa (E.) ventrocarinata sp. n. differs from E. (E.) redunca sp. n., E. (E.) sphaerocornis sp. n., and E. (E.) truncatiacantha sp. n. by the superior processes of the genital cup with a smooth and short carina (the other species with crenulate and high carina).
Distribution (Fig. 72). BRAZIL: Minas Gerais.
