Edessa eucnema  sp. n.

( Figs 5View FIGURE 5, 7 C–DView FIGURE 7, 8 EView FIGURE 8, 9View FIGURE 9)

Etymology. Reference to the small black spots on legs. Euknemos—with beautiful legs.

Holotype male. BRAZIL, Santa Catarina: Rio Vermelho, III–1964, Dirings (27°29’28.89”S 48°24’58.45” W) ( MZUSPAbout MZUSP).GoogleMaps

Measurements. Head length (1.1–1.8); head width (2.2–2.9); pronotum length (2.1–2.6); pronotum width (5.8–7.2); scutellum length (4.7–5.8); scutellum width (3.7–4.8); length of antennal segments (I: 0.6–0.8; II: 0.8– 1.2; III: 0.8–1.5; IV: 1.2–2.0; V: 1.9–2,1); total length (10.4–13.4); abdominal width (6.1–7.7).

Diagnose. Pronotum smooth. Arms of the anterior bifurcation of the metasternal process short and laterally inclined ( Fig. 5EView FIGURE 5); excavation very short receiving only the apex of the fourth rostral segment. Peritreme reaching half of the distance between ostiole of the scent gland and lateral margin of the body ( Fig. 8EView FIGURE 8). Evaporatorium with a long and raised crest in mesopleuron delimited by sulci; contiguous margin of meso and metapleuron barely raised; metapleuron with two barely raised crests one short medial and the other long distal. Spiracles concolorous with ventral surface. Trichobothria in yellowish calli. Antennomeres I–III and legs with small brown spots.

Male ( Figs 5 A–CView FIGURE 5). Superior process of the genital cup formed by tiny brown tubercles. Ventral part of the paramere with two distinct lobes, one globose and the other digitiform and distinctly projected posteriorly; base of the paramere narrower than distal part.

Female ( Fig. 5 DView FIGURE 5). Gonocoxites 8 setulose; distal margin sinuous, forming two small tooth-like projections on lateral angles; sutural border divergent distally. Laterotergites 9 with base wrinkled and excavated.

Comments. Edessa eucnema  sp. n. is easily identified by the spotted legs and antenna while the other species are spotless. Females show gonocoxites 8 with tooth-like projections differently from the other species with rounded outline, though the females of Edessa exigusternata  sp. n. and E. rugulata  sp. n. are unknown at present. Distribution ( Fig. 9View FIGURE 9). Brazil: Minas Gerais, São Paulo, Paraná, Santa Catarina and Rio Grande do Sul.
