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 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 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 D). ChL 0.85; ChW1 0.39; ChW2 0.38. Legs as in Figs. 45 E–G. Palp as in Figs. 45 H–K. Cymbium wider than long (0.61 long, 0.72 wide). Cymbial flap with indentations ( Figs. 45 H, J).

Female paratype. Habitus as in Figs. 46 A–C. Total length 5.95. Cephalothorax 2.49 long, 4.09 wide, 0.79 high; abdomen 3.46 long, 1.86 wide, 3.24 high. Fovea as in Fig. 46 L. Sternum light orange, 1.40 long, 0.94 wide. Labium darker than the sternum, 0.4 long, 0.3 wide. Clypeus 0.15 high. AME inter-distance 0.17; PME interdistance 0.09; PME–AME distance 0.21; AME–ALE distance 0.14; PME–PLE distance 0.35. Chelicerae as in Figs. 46 G–J. ChL 1.13; ChW1 0.49; ChW2 0.46. Legs as in Figs. 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 B–C). Spermathecae rounded, less than one diameter apart, not externally fused ( Figs. 47 C–D); accessory glands clustered close to fertilization ducts ( Figs. 47 D–E). Spinnerets as in Figs. 47 F–I.

Distribution. Known from the Amazonian regions of Brazil, Colombia and Ecuador ( Fig. 48 ).
