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.
