(Figures: 36–39, 56, 59)

Etymology. The specific name is related to the species’ habitat.

Material examined. Holotype male. FRENCH GUIANA. Saint Laurent du Maroni: Haut Maroni, La Forestiére, Jun, coll. Le Moult (MNHN).

Measurements. Total length: 10.4; head length: 1.2; head width: 2.3; pronotal length: 2.1; pronotal width: 6.1; abdominal width: 5.4; length of antennal segments (I: 0.5; II: 0.9; III: 1.2).

Male: Pygophore with dorsal rim concave ( Fig. 36 ) and furrowed; posterolateral angles developed (Fisg. 36, 38). Genital cup processes subtriangular, large, shallowly concave, located lateral to proctiger ( Fig. 37 ); apex posteriorly projected and surpassing dorsal rim in lateral view ( Figs. 36–37 ). Parameres flat, subtriangular; anterior expansion triangular and large, distal margin sloping, distal expansion truncate and directed lateroposteriorly; apex expanded downwards and not surpassing dorsal rim ( Figs. 37, 39 ). Dorsal face of the proctiger as long as wide, whole, without a distal shallow concavity ( Figs. 36–37 ). Lateral face of the proctiger slightly constricted ( Fig. 36 ). Lateral expansion of proctiger trapezoidal, large, three or more times wider than the anal opening, and curved; projected dorsally, beyond the dorsal face, apex of lateral arms rounded and posteriorly projected ( Figs. 36–38 ). Ventral rim with lobes not reaching the posterolateral angle level ( Fig. 38 ).

Comments. The new species Paraedessa silvicola is recognized by having posterolateral angles more developed than in other species; shape of parameres and ventral rim of the pygophore with shallow excavation.

Distribution ( Fig. 59 ): FRENCH GUIANA: Saint Laurent du Maroni.
