Paraedessa albomaculata Silva & Fernandes sp. nov.

(Figures: 11–15, 51, 59)

Etymology. Named after the white spots at the abdomen’s dorsal surface.

Material examined. Holotype male. SURINAME. Paramaribo: 12-1-1958, P. H. v. Doesburg Jr. (RMNH).

Paratypes. SURINAME. Paramaribo: ♀ Paramaribo, 5-10-1957, P. H. v. Doesburg Jr. (UFRG); ♀ 2-11-1958 (RMNH); ♀ ♂ 1963 (RMNH); ♂ no data (UFRG).

Measurements. Total length: 10.7–11.7; head length: 1.3–1.6; head width: 0.9–1.4; pronotal length: 2.0–2.6; pronotal width: 5.7–6.8; abdominal width: 5.5–6.3; length of antennal segments (I: 0.5–0.9; II: 0.9–1.2; III: 1.0– 1.4; IV: 2.3–2.4; V: 2.9).

Male: Dorsal rim of pygophore concave and slightly furrowed; posterolateral angle not developed ( Figs. 11– 13 ). Genital cup processes triangular, long, concave and located lateral to proctiger; apex surpassing the posterior limits of the pygophore ( Figs. 11–13 ). Parameres flat, narrow; distal margin sloping; anterior expansion digitiform and long, single distal expansion truncate and lateroposteriorly directed ( Figs. 11-14 ); apex not surpassing posterior limits of pygophore in dorsal view ( Fig. 11–12 ). Dorsal face of proctiger as long as wide, entire, without a distal shallow concavity. Lateral face of proctiger with slight constriction ( Fig. 11 ). Lateral expansion of proctiger cordiform, narrow, twice as wide as anal opening, posteriorly curved, projected dorsally beyond above the dorsal face ( Figs. 11–13 ). Ventral rim with lobes not reaching level of posterolateral angle ( Fig. 13 ).

Female: Gonocoxites 8 narrow, with sinuous distal margin, medially separated; posterolateral angle projected and dentiform, reaching or surpassing posterior margin of gonapophyses 8 ( Fig. 15 ); gonocoxites 8 overlapping gonapophyses 8 for most of its length.

Comments. Paraedessa albomaculata sp. nov. is recognized by the cordiform shape of the lateral expansion of proctiger; genital cup processes triangular and long; the shape of gonocoxites 8. This species and P. stolida have very similar gonocoxites 8, but in P. albomaculata they are wider and the angle is rounded instead of acute ( P. stolida ), and reaches or surpasses the distal margin of gonapophyses 8. This species and P. silvicola sp. nov., share the distal margin of parameres sloping and distal part of the paramere truncate and curved.

Distribution ( Fig. 59 ): SURINAME: Paramaribo.
