MORPHOTYPE: Female from Ecuador: Orellana, 1 km S Onkone Gare Camp, Reserva Etnica Waorani, 216 m, -0.65715°, -76.45300°, Feb. 13, 1996, T. Erwin et al., deposited in USNM, PBI_ OON 37553.

DIAGNOSIS: The females are similar to those of OMI038 and OMI021 from which they can be distinguished by the general shape of the anterior receptaculum and the size of the internal pockets (figs. 201, 220A, 224A, 229A).

DESCRIPTION: Habitus as in figure 199A, D. Spinnerets as in figure 200. GENITALIA: External pockets absent, internal pockets present, well developed; anterior receptaculum with massive lateral projections, short anterior apodemes; posterior receptaculum present, posterior apodeme formed by entire plate (figs. 201, 220A, 224A, 229A).

DISTRIBUTION: Known from Colombia, Ecuador, Peru and Brazil (map 15).
