Type material: Holotype: male from road to Manu, km 165, Consuelo, Cusco, Peru, litter under crown of fallen tree, 7 October 1982, L.E. Watrous & G. Mazurek leg. ( FMNH 0 33 572, PBI _OON 10079). Paratype: one female from Tambopata, Madre de Dios, Peru (12°34'23.02"S, 69°12'50.06"W), litter under crow of fallen tree, 28 October 1982, L.E. Watrous & G. Mazurek leg. ( FMNH 0 33 543, PBI _OON 10050).

Etymology. The specific name is a noun in apposition and refers to the ancestral people who lived in the region where the specimens were collected.

Diagnosis. Males resemble those of N. coca sp. nov. ( Figs 49, 50, 54 View FIGURES 48 – 55 ), N. beni sp. nov. ( Figs 108–111 View FIGURES 108 – 115 ) and N. tuparro sp. nov. ( Figs 127, 128, 131, 132 View FIGURES 125 – 138 ) by the smooth carapace, with enlarged setal sockets on the posterior surface, unmodified sternum, and absence of denticles on abdominal dorsal scutum ( Figs 71–73, 75 View FIGURES 71 – 80 ). Differ from those of N. coca sp. nov. ( Fig. 58 View FIGURES 56 – 61 ) by the presence of a prolateral, proximal embolar lamella ( Fig. 87 View FIGURES 81 – 88 ); from those of N. beni sp. nov. ( Fig. 11 View FIGURES 3 – 12 ) by the shorter embolar apical projection ( Fig. 5 View FIGURES 3 – 12 ) and from those of N. tuparro sp. nov. ( Figs 12 View FIGURES 3 – 12 , 138 View FIGURES 125 – 138 ) by the absence of an additional, retrolateral embolar process ( Figs 5 View FIGURES 3 – 12 , 78 View FIGURES 71 – 80 , 86 View FIGURES 81 – 88 ). Females differ from those of N. coca sp. nov. ( Fig. 62 View FIGURES 62 – 70 ) by the smooth carapace and from those of N. beni sp. nov. ( Fig. 15 View FIGURES 13 – 18 ) by the genital median element placed anteriorly ( Fig. 14 View FIGURES 13 – 18 ).

Description. Male (PBI_OON 10680): total length 2.30. Cephalothorax: carapace dark red-brown, broadly oval, pars cephalica slightly elevated, posterolateral surface without spikes, surface and sides smooth; lateral margin with small denticles ( Figs 74–75 View FIGURES 71 – 80 ); posterior part with one pair of well-developed tubercles ( Figs 75 View FIGURES 71 – 80 , 82 View FIGURES 81 – 88 ); recurved set of setae on posterior surface with four small tubercles ( Fig. 82 View FIGURES 81 – 88 ). Clypeus margin slightly reborded, straight in frontal view ( Fig. 74 View FIGURES 71 – 80 ). Sternum as long as wide, dark red-brown, with smooth surface.

Palp proximal articles, bulb and cymbium pale orange. Embolus without prolateral prong, apical projection truncated ( Figs 86, 88 View FIGURES 81 – 88 ).

Female (PBI_OON 10680): total length 2.56. Cephalothorax: carapace posterior surface with two pairs of tubercles ( Fig. 93 View FIGURES 89 – 98 ). Clypeus high ( Fig. 95 View FIGURES 89 – 98 ).
