Measurements. Total length: 11.6–12.7; head length: 1.1-1.4; head width: 2.4–3.0; pronotal length: 2.4–2.6; pronotal width: 7.0–7.8; abdominal width: 6.8–7.0; length of antennal segments (I: 0.5–0.6; II: 1.0–1.2; III: 1.1– 1.6; IV: 1.9–2.6; V: 2.5–2.7).

Male: Pygophore with dorsal rim slightly concave, rugose and posterolateral angle not developed ( Fig. 26 ). Genital cup processes subtriangular, small, slightly concave, emerging closer to posterolateral angle; apex rounded, surpassing the dorsal rim in lateral view ( Fig. 27 ). Parameres flat, falcate and small; anterior expansion digitiform and short ( Figs. 26-27, 29 ); apex acute ( Figs. 27, 29 ) not reaching the dorsal rim. Dorsal face of proctiger short, with a distal shallow concavity ( Figs. 26–27 ). Lateral face of proctiger with slight constriction ( Fig. 26 ). Expansion of posterior face projected dorsally, not reaching the level of dorsal face ( Figs. 26–27 ). Lateral expansion of proctiger well developed, triangular, large, four or more times wider than anal opening and gently curved ( Fig. 27 ). Ventral rim posteriorly projected with lobes developed, surpassing the level of posterolateral angle and hiding proctiger in ventral view ( Fig. 28 ).

Female: Gonocoxites 8 half-moon shaped, greatly reduced, laterally placed, widely separated medially; distal angle dentiform, long, projected, closer to middle line than proximal angle and contiguous with gonapophyses 8 ( Fig. 30 ). Gonocoxites 8 overlapping gonapophyses 8 in all of its extension.

Comments. Paraedessa heymonsi is recognized by having the genital cup processes small, subtriangular and emerging close to posterolateral angle that is not so developed as in other species, this impression is reinforced by ventral rim projected occulting proctiger in ventral view. Other helpful characteristics to recognize this species are parameres with the apex acute; dorsal face of proctiger short, three times wider than long; lateral expansion of proctiger triangular, much more developed than in other species; gonocoxites 8 with distal angle closer to middle line than proximal angle. This species shares the large lateral expansion of proctiger with P. ecuadoriensis sp. nov., P. paravinula , P. silvicola sp. nov. and P. verhoeffi . The parameres with apex acute and dorsoposteriorly directed is shared with P. verhoeffi .
