TYPE: Male holotype from Ecuador: Orellana: 1 km S Onkone Gare Camp, Reserva Etnica Waorani, 216 m, -0.65715°, -76.45300°, July 06, 1995, T. Erwin et al., deposited in USNM, PBI_ OON 30229.

ETYMOLOGY: A noun in apposition; the name is a reference to the modifications of chelicerae reminiscent of those of the genus Predatoroonops Brescovit et al. (2012) .

DIAGNOSIS: Males can be distinguished by the following combination of characters: carapace with two sclerotized stripes on both sides (fig. 86D), clypeus sinuous (fig. 86C), chelicerae strong, modified, with swollen median part and a projection on the promargin (fig. 86C, D), cheliceral fangs slightly sinuous with bifid tips, copulatory bulb with short embolus and a short, strong, prolateral spinelike apophysis (figs. 97A– C, 102A–C).

MALE (PBI_OON 30229): Total length 1.11. CEPHALOTHORAX (fig. 86): Carapace with sclerotized stripes along margin of cephalic area, wide in dorsal view (fig. 86A), anteriorly narrowed to 0.49× its maximum width or less. Clyp- eus sinuous in front view, vertical in lateral view (fig. 86C, D). Sternum wider than long (fig. 86B). Chelicerae, endites, labium orange-brown. Chelicerae anterior face with swollen median part, promargin with cuticular projections, fang tips bifurcated (fig. 86C, D). Labium rectangular.

LEGS: Yellow. GENITALIA: Palp proximal segments yellow; cymbium yellow; bulb with one short, spine-shaped apophysis near base of embolus; embolus light, short; sperm duct slightly coiled (figs. 97A–C, 102A–C).

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

DISTRIBUTION: Known only from the type locality in Ecuador (Orellana, map 10).

OTHER MATERIAL EXAMINED: Same data as holotype, Oct. 08, 1995, T. Erwin et al., 13 (USNM, PBI_ OON 43278).
