TYPES: Male holotype from Ecuador: Orellana: 1 km S Onkone Gare Camp, Reserva Etnica Waorani , 216 m, -0.65715°, -76.45300°, Jun. 26, 1996, T. Erwin et al., deposited in USNM, PBI_ OON 37671 ; same data, Jun. 26, 1996, T. Erwin et al., 1 male paratype deposited in USNM, PBI_ OON 51197 .

ETYMOLOGY: The specific name is a noun in apposition, and refers to the colloquial name with which the spiders of the family Oonopidae are known.

DIAGNOSIS: Males can be distinguished by the shape of the copulatory bulb, with short embolus and a weakly sclerotized apophysis extending beyond the embolus (figs. 88, 92A–C, 102D, E).

MALE (PBI_OON 37671): Total length 0.95. Habitus as in figure 87A.

CEPHALOTHORAX: Carapace with sclerotized stripes along margin of cephalic area (fig. 87B, E, F). Clypeus as in figure 87D. Sternum as long as wide. Anterior face of chelicerae with basal conical projections (fig. 87D). Labium rect- angular. ABDOMEN: Round, white. GENITA- LIA: Bulb with weakly sclerotized apophysis extending beyond tip of embolus; embolus very short; sperm duct coiled with many loops (figs. 88, 92A–C, 102D, E).

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

DISTRIBUTION: Ecuador, Colombia, and Peru (map 11).
