Figures 211C–E , 220D , 224D , 230C , map 17

MORPHOTYPE: Female from Ecuador: Orellana, 1 km S Onkone Gare Camp, Reserva Etnica Waorani, 216 m, -0.65715°, -76.45300°, Oct. 8, 1995, T. Erwin et al., deposited in USNM, PBI_ OON 50060.

DIAGNOSIS: Females are similar to those of OMI038 and OMI021 by the general morphology of genitalia, but in OMI036 the lateral projections of anterior receptaculum are wider than in OMI021. Additionally, in OMI021 the anterior apodemes are longer (compare fig. 220B–D).

DESCRIPTION: Habitus as in figure 211C–E.

GENITALIA: External pockets absent, internal pockets small; posterior receptaculum absent, posterior apodeme formed by entire plate (figs. 220D, 224D, 230C).

DISTRIBUTION: Ecuador and Brazil (map 17).
