Figures 73–84View FIGURES 73–84

TYPES: Male holotype and three female paratypes taken from litter along stream at Pillahuata, Manu Road, km 128, Cusco, Peru (Sept. 26, 1982; L. Watrous, G. Mazurek), deposited in FMNH (33541, PBI_ OON 10048View Materials)  .

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

DIAGNOSIS: Males resemble those of P. desultrix  but have the embolus much narrower at the point at which it is bent (fig. 78); females have a wider tip on the anterior genitalic process, and also differ from those of P. yungas  in having the genital atrium relatively long and narrow (figs. 83, 84).

MALE (PBI_ OON 10048View Materials, figs. 73–80): Total length 2.31. Surface of elevated portion of pars cephalica appearing finely reticulate; lateral margin with blunt denticles. ALE separated by less than their radius. Postepigastric scutum long, almost rectangular, extending to nearly full length of abdomen. Leg spination: femora: I p0-0-2, r1-1-1; II p0-0-2, r0-1-0; tibiae: I v4-4-2; II v4-4-1p; metatarsi: I v2-1p-2; II v3-0-2. Embolus relatively long, tip sinuous; conductor relatively narrow, with slight prolateral projection at base, tip recurved.

FEMALE (PBI_ OON 10048View Materials, figs. 81–84): Total length 2.49. ALE separated by their radius to diameter. Dorsal scutum covering full length of abdomen, no soft tissue visible from above, fused to epigastric scutum. Postepigastric scutum almost semicircular, fused to epigastric scutum. Leg spination: femora: I p0-0-2, r1-1-1; II p0-0-2, r2-1-1; tibiae I, II v4-4-2; metatarsi: I v2-1p-2; II v3-0-2. Genital atrium long, semicircular, posterior half occupied by sclerotization, anterior genitalic process relatively wide.

ETYMOLOGY: ffie specific name is a noun in apposition taken from the habitat data.

Leg spination: femur I p0-0-2, r1-1-0; tibiae I, II v4-4-1p; metatarsi: I v2-1p-2; II v3-0-2. Embolus long, abruptly bent at about half its length, slightly bent again near tip; conductor with large dorsal expansion.

FEMALE (PBI_OON 971, figs. 93–96): Total length 2.28. Dorsal scutum covering full length of abdomen, no soft tissue visible from above, not fused to epigastric scutum. Postepigastric scutum almost semicircular, fused to epigastric scutum. Leg spination: femora: I p0-0-2, r1-1-1; II p0-0-2, r1-1-0; tibiae: I v4-4-2; II v4-4-1p; metatarsi: I v2-2-2; II v3-0-2.
