(MPEG 10666, PBI _OON 44397); one female from Lago Taraíra, Bajo Rio Apaporis, Estación Biológica Caparú, Taraira, Vaupés, Colombia (01°04'N, 69°29'W), 2 April 2004, J. Pinzón leg.

Etymology. The specific name is to be treated as a Latin adjective, referring to the distribution of this species in the Amazon Forest.
Diagnosis. Males resemble those of N. coca sp. nov. (Fig. 58) by the squared embolar apical projection and by the presence of a prolateral, distal, embolar lamella (Fig. 32), but differ by the texturized carapace surface, bearing two pairs of posterior enlarged setal sockets (Fig. 52). They differ from those of all other species of the genus in having a particularly large ejaculatory opening (Fig. 29). Females resemble those of N. yekuana sp. nov. (Fig. 160) by the presence of a pair of posterior bumps, bearing a cluster of modified setal sockets, on the carapace posterior surface (Fig. 41), but differ from this species by the low clypeus, less than one AME diameter in height (Fig. 42).
Description. Male (PBI_OON 44096): total length 2.12. Cephalothorax: carapace orange-brown, broadly oval, pars cephalica strongly elevated, posterolateral surface without spikes, surface of elevated portion smooth, sides granulate, lateral margin with small denticles; posterior pars with one or two pairs of small tubercles (Fig. 23); recurved set of setae on posterior surface with six small tubercles (Fig. 24). Clypeus margin slightly reborded, straight in frontal view, high (Fig. 22). Sternum as long as wide, orange-brown, surface smooth. Endites and labium orange-brown. Abdomen: book lung covers large, round. Dorsal scutum orange-brown, middle surface and sides smooth, anterior half without projecting denticles (Fig. 27). Epigastric and postepigastric scutum orange-brown. Legs: pale orange. Leg spination: tibia I v4-4 -0; metatarsus I v2-2 -0. Genitalia: epigastric region with small and circular sperm pore. Palp with proximal articles, cymbium and bulb yellow. Embolus oblong, with short apical projection (Fig. 32), without prolateral prong or prolateral lamella (Figs 32 – 34).
Female (PBI_OON 44360): total length 2.28. Cephalothorax: carapace with pars cephalica slightly elevated in lateral view, with granulate surface (Fig. 35); lateral margin without denticles; posterior part with five or more tubercles (Fig. 41); recurved set of setae on posterior surface with nine or more small tubercles (Fig. 41). Dorsal abdominal scutum middle surface and lateral sides finely reticulate (Figs 46 – 47). Leg spination: femur I v0-0-2; tibia I v2-2 -1; II v4-2 -2; metatarsus I v4-1 -0; II v2 -0-2. Genitalia: atrium wide (Fig. 45); median element straight (Fig. 13).
