Measurements. Total length: 11.2–12.5; head length: 1.2–1.4; head width: 2.5–2.6; pronotal length: 2.2–2.5; pronotal width: 6.6–7.3; abdominal width: 6.1–6.8; length of antennal segments (I: 0.6–0.8; II: 1.1–1.2; III: 1.5– 1.6; IV: 2.5–2.7; V: 2.7).
Male: Pygophore with dorsal rim slightly concave (Fig. 21), furrowed and posterolateral angle poorly developed (Figs. 21, 23). Genital cup process ogival, long, curved, located lateral to proctiger; apex rounded, curved posteriorly, surpassing the dorsal rim in lateral view (Figs. 21–22). Parameres flat, mesial surface shallowly concave; anterior expansion digitiform and short, apex bifid due to small dark lobes (Figs. 21–22, 24); apex barely surpassing dorsal rim in lateral view (Fig. 22). Dorsal face of proctiger twice as wide as long; with a distal shallow concavity (Figs. 21–22). Lateral face of proctiger with a slight constriction (Fig. 21). Lateral expansion of proctiger trapezoidal to cordiform, large, three or more times wider than the anal opening, concave; apices rounded and directed posteriorly, projected dorsally, almost reaching the level of dorsal face (Figs. 21–23). Ventral rim with developed lobes, not reaching the level of the posterolateral angles (Fig. 23).
Female: Gonocoxites 8 subtriangular, greatly reduced, laterally displaced and widely separated medially; posterolateral angle not notably developed or projected and contiguous with gonapophyses 8 (Fig. 25). Gonocoxites 8 overlapping gonapophyses 8 in all of its extension.
Comments. Paraedessa ecuadoriensis sp. nov. is recognized by having an ogival genital cup process; parameres with bifid apex; lateral expansion of proctiger trapezoidal or cordiform; gonocoxites 8 subtriangular and greatly reduced. This species shares the lateral face of the proctiger slightly constricted with P. albomaculata sp. nov., P. heymonsi, P. paravinula, P. silvicola sp. nov., P. stolida and P. verhoeffi. The species P. ecuadoriensis sp. nov., P. heymonsi and P. verhoeffi have the dorsal face of proctiger with distal shallow concavity and gonocoxites 8 greatly reduced.
Distribution (Fig. 59): COLOMBIA: Meta; ECUADOR: Sucumbios, Napo, Orellana.
