Measurements. Total length: 10.1–12.1; head length: 1.0–1.4; head width: 2.4–2.6; pronotal length: 2.3–2.5; pronotal width: 6.3–7.2; abdominal width: 5.4–6.7; length of antennal segments (I: 0.4–0.5; II: 1.0–1.1; III: 1.2– 1.6; IV: 2.3–2.7; V: 2.3–2.8).

Male: Pygophore with dorsal rim concave and furrowed ( Fig. 45 ); posterolateral angles not developed ( Figs. 45, 47 ). Genital cup processes elongated, narrowed gradually towards the apex, barely concave, emerging near proctiger; rounded to acuminated apex, slightly surpassing the dorsal rim in lateral view ( Fig. 46 ). Parameres flat, triangular, long and curved; anterior expansion digitiform and small ( Figs. 45–46, 48 ); apex acute and surpassing dorsal rim in lateral view, surpassing the posterior limits of the pygophore in ventral view ( Fig. 47 ). Dorsal face of proctiger very short; with distal shallow concavity ( Figs. 45–46 ). Lateral face of the proctiger with a slight constriction ( Fig. 45 ). Lateral expansion of proctiger trapezoidal, curved, large, three times wider than the anal opening and with acute lateral angles; projected dorsally, almost reaching the dorsal face ( Figs. 45–46 ). Ventral rim with lobes slightly developed, not reaching level of posterolateral angle ( Fig. 47 ).

Female: Gonocoxites 8 half-moon shaped, greatly reduced, laterally placed, widely separated medially; proximal angle closer to middle line than distal angle; distal angle dentiform, short, curved and contiguous with gonapophyses 8 ( Fig. 49 ). Gonocoxites 8 overlapping gonapophyses 8 in all of its extension.

Comments. This is the first description of the male. Paraedessa verhoeffi is identified by the elongated genital cup process, with rounded to acuminated apex; parameres triangular; dorsal face of the proctiger very short compared with other species, around four times as wide as long; ventral rim slightly excavated and gonocoxites 8 half-moon shaped with proximal angle closer to middle line than distal angle. This species and P. ecuadoriensis sp. nov., P. silvicola sp. nov. and P. stolida share a quite similar shape of the lateral expansion of proctiger. This species share some similarities in the genitalia of both sexes with P. heymonsi .
