TYPES: Male holotype from Bolivia: Santa Cruz: Guarayos: Concesión Forestal La Chonta , Amazon forest with selective logging, understory, 330 m, - 15.71166 °, - 62.77222 °, Oct. 26, 2010, to Oct. 30, 2010, Grismado, C., Vacaflores, M.R., and Pérez, M. ( CBF PBI_OON 43124 ). Deposited in CBF. Same data, one male and one female paratypes (MACN-AR 26911 PBI _ OON 43125, MACN-AR 26910 PBI _ OON 43136), deposited in MACN-Ar ; and two female paratypes ( CBF PBI _ OON 43127, CBF PBI _ OON 43128), deposited in CBF .

ETYMOLOGY: The specific name of this species is a patronym in honor of the Argentine ornithologist Cecilia Kopuchian (MACN), who invited the first author on the field trip to Bolivia, and in recognition of her help and support in that campaign.

DIAGNOSIS: N. kopuchianae males are very similar to those of N. caparu by the shape of the bulb and its terminal elements, but differ by the bulb being distally more tapering, and in lacking a small protrusion in the embolus, where the filiform part arises (figs. 114B–D, 116D). Females also resemble those of N. caparu by the T-shaped anterior receptacle, but its transverse projections are longer (fig. 116C).

DESCRIPTION: MALE (holotype, PBI_OON 43124). Total length 1.69. Cephalothorax: Carapace yellow, broadly oval in dorsal view, pars cephalica strongly elevated in lateral view, anteriorly narrowed to less than half their maximum width; lateral margin straight; nonmarginal pars cephalica setae absent, seem to be lost in the type specimen; nonmarginal pars thoracica setae dark, needlelike; marginal setae dark, needlelike. Clypeus setae dark, needlelike. Eyes on a darkened pigmented area, all subequal, all eyes oval; posterior eye row straight from front; ALE separated by their radius to diameter, ALE-PLE separated by less than ALE radius, PME touching throughout most of their length, PLE-PME separated by less than PME radius. Sternum longer than wide, yellowish white, anterior margin unmodified, posterior margin not extending posteriorly of coxae IV; setae sparse, evenly scattered. Mouthparts: chelicerae, endites, and labium yellowish white; cheliceral setae light, evenly scattered. Labium anterior margin indented at middle; with 1 or 2 setae on anterior margin. Endites distally excavated, with a subdistal unsclerotized ring that separate an apical segment, with a rolled tip (fig. 113E). Abdomen: Dorsum pale white. Book lung covers elliptical. Postepigastric scutum yellow. Spinneret scutum absent. Dorsum setae dark, needlelike. Colulus represented only by setae. Legs: Yellow; femur IV thickened, much larger than femora I–III (fig. 113C). Leg spination: leg I: femora d1-0, tibiae v2-2- 2-2-2-0, metatarsi v2-2-2-2; leg II: femora d1- 0, tibiae v2-2-2-2-2-0, metatarsi v2-2-2-2; leg III: femora d1-1, tibiae d1, p1-1, r1-1, v1-2ap, metatarsi d0-0-1, p1-1, r1-1, v2ap; leg IV: femora d1-1, tibiae d1, p1-1, r1-1, v1-2ap, metatarsi d0-0-1, p1-1, r1-1, v1-0-2ap. Trichobothria not examined. Genitalia: Palp proximal segments yellow; femur normal size, two or more times as long as trochanter; cymbium yellow, ovoid in dorsal view, not fused with bulb; bulb white, 1 to 1.5 times as long as cymbium, slender, tapering apically; conductor distally straight and acute; embolus dark, thick, and gently curved in the proximal half, abruptly narrowed, almost thread shaped, in the distal half (figs. 114B–D, 116D).

FEMALE (PBI_OON 43127). Total length 2.28. As in male except as noted. Cephalothorax: Carapace nonmarginal pars cephalica setae needlelike, in U-shaped row. Eyes on a darkened pigmented area. Sternum precoxal triangles present; setae dark. Labium elongated hexagon. Palp spines absent. Abdomen: Postepigastric area setae dark, needlelike. Legs: Patella plus tibia I nearly as long as carapace. Leg spination: leg I: femora d1-0, tibiae v2-2-2-2-2-0-0, metatarsi v2-2-2-2; leg II: femora d1-0, tibiae v2-2-2-2-2-0-0, metatarsi v2-2-2-2; leg III: femora d1-1, tibiae d1, p1-1, r1-1, v1-2ap, metatarsi d1-0-1, p1-1, r1- 1, v1-0-2ap; leg IV: femora d1-1, tibiae d1, p1-1, r1-1, v1-2ap, metatarsi d1-0-1, p1-1, r1- 1, v1-0-2ap. Genitalia: Dorsal view: anterior receptacle T-shaped, without conspicuous lumen, with wide and sclerotized basal section with a small, rounded opening; dorsal plate nearly rectangular, as long as anterior receptacle (fig. 116C).

OTHER MATERIAL EXAMINED: None.

DISTRIBUTION: Only know from the type locality, in Santa Cruz Department, Bolivia (map 6).

NATURAL HISTORY: The specimens have been taken by beating foliage, especially from plant parts with accumulations of suspended soil, detritus, dead leaves, and twigs. The type locality is in an area of Amazon forest with selective logging.
