TYPES: Male holotype from Ecuador: Orellana, Tiputini Biodiversity Station, near Yasuní National Park , 250 m, -0.63194°, -76.14416°, July 04, 1998, T. Erwin et al., deposited in USNM, PBI_OON 37647 ; 1 km S Onkone Gare Camp, Reserva Etnica Waorani , 216 m, -0.65715°, -76.45300°, Oct. 08, 1995, T. Erwin et al., 1 male paratype deposited in USNM, PBI_OON 30217 .

ETYMOLOGY: A noun in apposition; Shuar are indigenous inhabitants of Ecuador and Peru.

DIAGNOSIS: Males resemble to those of O. mancocapac by having a strong apophysis, covered by short cusps on the copulatory bulb (fig. 93G–I), but in O. shuar this apophysis is longer and cylindrical.

MALE (PBI_OON 37647): Total length 1.13. Habitus as in figure 65A. CEPHALOTHORAX (fig. 65D–G): Carapace orange. Clypeus slightly sinuous in frontal view. Sternum as long as wide. Anterior face of chelicerae with basal anterior blunt projections, promargin with cuticular projections (fig. 65F, G, arrow). Labium rectangular. Endites anteromedian tip with one strong, toothlike projection. ABDOMEN: Pale white. LEGS: Yellow. GENITALIA: Bulb tapering apically, with one strong, huge apophysis covered by short cuticular projections; embolus light, base with one short, spine-shaped apophysis; sperm duct coiled, with many loops (figs. 93G–I, 100J–L).

FEMALE: Unknown; females of morphospecies MI020, MI022–MI023, MI025–MI027, MI029, MI036, and MI038 from the same area are candidates to match this male.

DISTRIBUTION: Known from the province of Orellana in Ecuador (map 10).
