Figures 214 , 226D–F , 231A, B , map 21

MORPHOTYPE: Male from Peru: Loreto: Pithecia, -5.18333°, -74.70000°, May 01, 1990, to June 01, 1990, T. Erwin, D. Silva, deposited in MUSM, PBI_OON 43310.

DIAGNOSIS: Males resemble those of O. mancocapac in having a serrated apophysis on the copulatory bulb, but can be distinguished by a significant difference in the general shape of the copulatory bulb and the apophysis (fig. 226D–F). In addition, both chelicerae are provided with only one toothlike projection instead of two, as occur in that species (fig. 214B).

DESCRIPTION: CEPHALOTHORAX (fig. 214): Carapace with brown stripe along margin of cephalic area, oval in dorsal view (fig. 214A). Chelicerae anterior face with conical projection (fig. 214B). Endites anteromedian tip with one short, toothlike projection, serrula present in single row. ABDOMEN: Missing. LEGS: Missing.

GENITALIA: Bulb prolateral margin with strong serrated apophysis near embolus base; embolus light, wide in lateral view; sperm duct slightly coiled (figs. 226D–F, 231A, B).

DISTRIBUTION: Known only from the morphotype locality (map 21).

OTHER MATERIAL EXAMINED: None.
