Figures 97–108

TYPES: Male holotype and female allotype taken in a flight intercept trap at a site 2 km northwest of Tumichuchua, Vaca Diez, 11°08.77′S, 66°09.91′W, Beni, Bolivia (Sept. 1, 1993; P. Parrillo, W. Rojas), deposited in FMNH (43140, PBI_OON 10683) .

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

DIAGNOSIS: Males resemble those of P. yungas but the palpal conductor is narrower, especially at the level of its prolateral spur (figs. 101–103); females have a much shorter postepigastric scutum (fig. 105).

MALE (PBI_OON 10683, figs. 97–104): Total length 1.69. Surface of elevated portion of pars cephalica appearing granulate; lateral margin without denticles. ALE separated by less than their radius. Postepigastric scutum almost semicircular, extending to about 3/4 of abdomen length. Leg spination: femur I p0-0-2, r1-1-0; tibiae: I v4-4-1p; II v4-4-0; metatarsi: I v2-1p-2; II v2-0-2. Embolus relatively short, weakly bent; conductor narrow throughout its length.

FEMALE (PBI_OON 978, figs. 105–108): Total length 2.20. Dorsal scutum covering more than 3/4 of abdomen length, more than 1/2 to most of abdomen width, not fused to epigastric scutum. Postepigastric scutum extending to about 2/3 of abdomen length, fused to epigastric scutum. Leg spination: femora I, II p0-0-2, r1-1-1; tibiae: I v4-4-2; II v4-4-1p; metatarsi: I v2-2- 2; II v3-0-2. Genitalic atrium semicircular.

OTHER MATERIAL EXAMINED: Bolivia: Beni: 2 km NW Tumichuchua, Vaca Diez , 11°8.77′S, 66°9.91′W, Nov. 1–9, 1993, flight intercept trap in forest (P. Parillo, W. Rojas, FMNH PBI_OON 978), 2♀ .
