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 ).
