Erwin et al., 1 male paratype deposited in USNM, PBI_OON 37130 ; same data, June 25, 1996, T. Erwin et al., 2 male paratypes deposited in USNM, PBI_OON 37118 .

ETYMOLOGY: The specific name is a noun in apposition taken from the type locality.

DIAGNOSIS: Males can be distinguished by the shape of the terminal portion of the copulatory bulb, consisting of a short, flattened embolus flanked by a short, spine-shaped apophysis (figs. 84, 94D–F).

MALE (PBI_OON 37136): Total length 1.35. Habitus as in figure 80D. CEPHALOTHORAX (fig. 80A–C): Carapace orange-brown (fig. 80B). Clypeus straight in front view (fig. 80A). Sternum wider than long. Chelicerae, endites, labium orange-brown; anterior face of chelicerae with basal blunt projections, fang with one tooth projection on base (fig. 81D). Labium rectangular. Endites anteromedian tip with one short, toothlike projection (fig. 81A, B). ABDOMEN: Pale white. LEGS: Metatarsus of at least leg I with special modified setae on prolateral side (fig. 84C–E). Tarsal proclaws, retroclaws inner face smooth; tarsi I, II, IV superior claws with nine or more teeth on lateral surface of proclaw, nine or more teeth on lateral surface of retroclaw. GENI-

TALIA: Bulb tapering apically; embolus flattened in dorsal view, short; sperm duct coiled, with many loops (figs. 84, 94D–F).

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

DISTRIBUTION: Known from the Orellana, Ecuador, and Mato Grosso, Brazil (map 13).
