TYPES: Male holotype and male paratype (with one immature) from Peru: Madre de Dios Department: Manu Province: Zona Reservada Pakitza , 356 m, - 11.93333 °, - 71.28333 °, June 01, 1992, T. Erwin, D. Silva ( MUSM-ENT 0501560 PBI_OON 43055 ). Deposited in MUSM.

ETYMOLOGY: This specific epithet is a noun in apposition taken from the type locality.

DIAGNOSIS: N. pakitza males are distinguished by the embolus with a small curled tip, and a broad, membranous conductor, nearly parallel to embolus in lateral view (figs. 111B–D, 116B); females by the mushroomlike anterior receptacle in combination to a nearly triangular posterodorsal plate (fig. 112H, 116A).

DESCRIPTION: MALE (holotype, PBI_OON 43055). Total length 1.77. Cephalothorax: Carapace yellow, broadly oval in dorsal view, pars cephalica slightly elevated in lateral view, anteriorly narrowed to between 0.5 and 0.75 times its maximum width; lateral margin undulate; nonmarginal pars cephalica setae absent; nonmarginal pars thoracica setae absent; marginal setae dark, needlelike. Clypeus setae absent. Eyes all subequal, ALE oval, PME circular, PLE circular; posterior eye row procurved from front; ALE separated by more than their diameter, ALE-PLE separated by less than ALE radius, PME touching for less than half their length, PLE-PME separated by less than PME radius. Sternum as long as wide, yellow, posterior margin not extending posteriorly of coxae IV; setae sparse, evenly scattered. Mouthparts: chelicerae, endites, and labium yellow; cheliceral setae dark, evenly scattered. Labium anterior margin indented at middle; with six or more setae on anterior margin. Endites distally not excavated, anterior margin with laterally directed laminar expansions (fig. 110E). Abdomen: Dorsum pale white. Book lung covers round. Postepigastric scutum yellow. Spinneret scutum absent. Dorsum setae dark, needlelike. Colulus absent. Legs: Yellow; femur IV slightly enlarged. Leg spination: leg I: femora pv0- 0-0-1-1, tibiae v2-2-2-2-2-0, metatarsi v2-2-2; leg II: tibiae v2-2-2-2-2-0, metatarsi v2-2-2; leg III: femora d1-1-1, tibiae p1-1, v1-ap, metatarsi r1, v1ap; leg IV: femora d0-1-1-1, tibiae d1, p1-1, v1-2ap; metatarsi p1-1, v1- 2ap. Trichobothria not examined. Genitalia (figs. 111B–D, 116B): Palp proximal segments pale orange; femur normal size, two or more times as long as trochanter; cymbium pale orange, ovoid in dorsal view, not fused with bulb; bulb yellow, more than two times as long as cymbium; conductor broad, elongated, membranous, nearly parallel to the embolus (in lateral view); embolus dark, with a small curled tip (fig. 116B).

FEMALE (PBI_OON 14822). Total length 1.75. As in male except as noted. Cephalothorax: Eyes ALE-PLE separated by ALE radius to ALE diameter, PME separated by less than their radius. Sternum precoxal triangles present; setae dark. Labium elongated hexagon. Palp spines absent. Abdomen: Postepigastric area setae dark, needlelike. Colulus represented only by setae. Legs: Femur IV not thickened, same size as femora I–III, patella plus tibia I nearly as long as carapace. Leg spination: leg I: femora pv0-0- 1-1-0, tibiae v2-2-2-2-2-0, metatarsi v2-2-2-2; leg II: femora pv0-0-1-1-0, tibiae v2-2-2-2-2- 0, metatarsi v2-2-2-2; leg III: metatarsi d1-0, p1-1, r0-1, v2ap; leg IV: metatarsi p1-1, r1-1, v2ap. Genitalia: Ventral view: anterior receptacle with long stalk and transversely mushroom-shaped terminal part, easily visible through the cuticle (fig. 112H). Posterior plate distally widened, shorter than anterior receptacle, laterally surpassing ends of transverse bar, resembles inverted triangle (fig. 116A).

OTHER MATERIAL EXAMINED: Same data as the types: 1♀ (MUSM-ENT 0501576 PBI _ OON 43053), 1♂, 1♀ ( MUSM-ENT 0501557 PBI _ OON 43054), 2♀ ( MUSMENT 0501576 PBI _ OON 43052) ; CICRA. 2do. Mirador, Mar. 04, 2006, M. Deza, 1♀ ( MEKRB PBI _ OON 14822) .
