TYPE: Male holotype from the Parque Estadual do Utinga, Belém, 01°25′29.29″S, 48°26′16.84″W, Pará, Brazil (Oct. 23–30, 2010; E. Costa et al.), deposited in MPEG (19219, PBI_OON 43648) GoogleMaps .

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

DIAGNOSIS: Males resemble those of P. desultrix , but the embolus is much narrower at its bend and the conductor has only tiny expansions on its prolateral and retrolateral sides (fig. 114); females have a wider tip on the anterior genitalic process (figs. 119, 120).

MALE (PBI_OON 38073, figs. 109–116): Total length 1.80. Surface of elevated portion of pars cephalica appearing finely reticulate; lateral margin without 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, r1-1-0; tibiae I, II v4-4-2; metatarsi: I v2-1p-2; II v2-0-2. Embolus relatively short, bent only near tip, closely paralleling conductor.

FEMALE (PBI_OON 38065, figs. 117–120): Total length 2.15. 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 almost semicircular, extending to about 3/4 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. Genital atrium semicircular, anterior genitalic process posteriorly narrow, with wide tip.
