Etymology. The species epithet is a noun in apposition taken after the Waorani people, a native Amerindian tribe from the Amazonian region of Ecuador (Napo, Orellana and Pastaza Provinces).

Diagnosis. Males of G. waorani can be recognized by their triangular white abdominal spots ( Fig. 45 View FIGURE 45 A). Females have the largest copulatory openings in the genus, almost as long as the septum, which is strongly constricted medially, resembling an hourglass in ventral view ( Fig. 47 View FIGURE 47 B).

Sternum pale yellow, 1.18 long, 0.89 wide. Labium darker than the sternum, 0.27 long, 0.25 wide. Clypeus 0.19 high. AME interdistance 0.16; PME inter-distance 0.09; PME–AME distance 0.17; AME–ALE distance 0.15; PME–PLE distance 0.25. Chelicerae dark orange ( Fig 45 View FIGURE 45 D). ChL 0.85; ChW1 0.39; ChW2 0.38. Legs as in Figs. 45 View FIGURE 45 E–G. Palp as in Figs. 45 View FIGURE 45 H–K. Cymbium wider than long (0.61 long, 0.72 wide).

Legs as in Figs. 46 View FIGURE 46 D–F. For palp and leg measurements see Table 10. Copulatory openings almost as long as septum, which is strongly constricted medially ( Figs. 47 View FIGURE 47 B–C). Spermathecae rounded, less than one diameter apart, not externally fused ( Figs. 47 View FIGURE 47 C–D); accessory glands clustered close to fertilization ducts ( Figs. 47 View FIGURE 47 D–E).
