Type material: Holotype: male, 2 km NW from Tumichucua, Vaca Diez, Beni , Bolivia (11°8’46.2”S, 66°9’54.6”W), F.I.T. Trap in forest, 01–09 December 1993, P. Parrillo & W. Rojas leg. ( FMNH, PBI _OON 10721). Paratype: one female, same data as holotype ( FMNH, PBI _OON 44362).

Etymology. The specific name is a toponym in apposition referring to the Bolivian department in which the types were collected.

Diagnosis. Males resemble those of N. coca sp. nov. ( Figs 49, 50, 54 View FIGURES 48 – 55 ), N. inca sp. nov. ( Figs 71–73, 75 View FIGURES 71 – 80 ) 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 108, 111 View FIGURES 108 – 115 ). Differ from those of N. coca sp. nov. ( Fig. 58 View FIGURES 56 – 61 ) by the absence of a prolateral, distal, embolar lamella; from those of N. inca sp. nov. ( Fig. 87 View FIGURES 81 – 88 ) by the absence of a prolateral, proximal embolar lamella and from those of N. tuparro sp. nov. ( Fig. 138 View FIGURES 125 – 138 ) by the absence of an additional, retrolateral embolar process. Females differ from those of N. coca sp. nov. ( Fig. 62 View FIGURES 62 – 70 ) by the smooth carapace and from those of N. inca sp. nov. ( Fig. 14 View FIGURES 13 – 18 ), by the genital median element placed posteriorly ( Fig. 15 View FIGURES 13 – 18 ).

Description. Male (holotype): total length 2.07. Cephalothorax: carapace orange-brown, pars cephalica strongly elevated; posterolateral surface without spikes, surface and sides smooth ( Fig. 108 View FIGURES 108 – 115 ); lateral margin with blunt denticles; posterior part with one pair of well-developed tubercles ( Fig. 108 View FIGURES 108 – 115 ), recurved set of setae on posterior surface with four small tubercles ( Fig. 108 View FIGURES 108 – 115 ). Clypeus margin slightly reordered, straight in front view, high. Sternum as long as wide, orange-brown; surface smooth, without pits ( Fig. 109 View FIGURES 108 – 115 ). Chelicerae, endites and labium orange-brown. Abdomen: book lung covers large and ovoid. Dorsal scutum orange-brown, middle surface and sides smooth, anterior half without projecting denticles ( Fig. 111 View FIGURES 108 – 115 ). Epigastric and postepigastric scutum orange-brown ( Fig. 110 View FIGURES 108 – 115 ). Legs: orange-brown. Leg spination: tibia I v2-4 -0; metatarsus I v2-2 -0. Genitalia: epigastric region with sperm pore small and circular ( Fig. 112 View FIGURES 108 – 115 ). Palp proximal articles, cymbium and bulb pale orange. Embolus longer than wide ( Fig. 113 View FIGURES 108 – 115 ).

Female (paratype): total length 2.18. Abdomen: dorsal scutum orange-brown, middle surface and sides smooth; groove connecting the posterior spiracles bearing pockets ( Fig. 124 View FIGURES 116 – 124 ). Legs: orange-brown. Leg spination: tibia I v6-2 -0; II v4-2 -0; metatarsus I v4-2 -0; II v2-2 -0. Genitalia: atrium narrow ( Figs 15 View FIGURES 13 – 18 , 124 View FIGURES 116 – 124 ).
