Figs 11, 15, 108 –124; Map 2
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), N. inca sp. nov. (Figs 71–73, 75) and N. tuparro sp. nov. (Figs 127, 128, 131, 132) 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). Differ from those of N. coca sp. nov. (Fig. 58) by the absence of a prolateral, distal, embolar lamella; from those of N. inca sp. nov. (Fig. 87) by the absence of a prolateral, proximal embolar lamella and from those of N. tuparro sp. nov. (Fig. 138) by the absence of an additional, retrolateral embolar process. Females differ from those of N. coca sp. nov. (Fig. 62) by the smooth carapace and from those of N. inca sp. nov. (Fig. 14), by the genital median element placed posteriorly (Fig. 15).
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); lateral margin with blunt denticles; posterior part with one pair of well-developed tubercles (Fig. 108), recurved set of setae on posterior surface with four small tubercles (Fig. 108). Clypeus margin slightly reordered, straight in front view, high. Sternum as long as wide, orange-brown; surface smooth, without pits (Fig. 109). 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). Epigastric and postepigastric scutum orange-brown (Fig. 110). 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). Palp proximal articles, cymbium and bulb pale orange. Embolus longer than wide (Fig. 113).
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). 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, 124).
Other material examined. BOLÍVIA: Beni: 1♂ 1♀, Vaca Diez, 2 km NW from Tumichucua (11°8’46.2”S, 66°9’54.6”W), 01–09 November 1993, Berlese on forest leaf litter, P. Parrillo & W. Rojas leg. (FMNH 0 43 137, PBI _OON 10680).
