Type material: Holotype: male from La Pedrera Quebrada el Ayo, La Pedrera, Amazonas, Colombia (01°35’N, 69°31’W), May 2002, J. Pinzon leg. ( ICN, PBI _OON 44329). Paratype: one female from Lago Taraira bajo Rio Apaporis, Estación Biológica Caparú, Taraíra, Vaupés, Colombia (01°04’N, 69°29’W), 0 2 April 2004, J. Pinzón leg. ( ICN, PBI _OON 44363).

Etymology. The specific name is a noun in apposition, referring to the indigenous tribe Macuna , which inhabited the type locality.

Diagnosis. Males resemble those of N. pure sp. nov. ( Fig. 227 View FIGURES 227 – 236 ), N. gregoblin (See Abrahim et al. 2012, figs 105, 108), N. petroglobin (See Abrahim et al. 2012, figs 185, 187) and N. boibumba (See Abrahim et al. 2012, figs 221, 224) by the combined presence of smooth carapace and denticles on the anterior portion of the abdominal dorsal scutum ( Figs 201, 204 View FIGURES 198 – 209 ). They differ from those of N. pure ( Fig. 229 View FIGURES 227 – 236 ), N. gregoblin (See Abrahim et al. 2012, fig. 105), and N. petroglobin (See Abrahim et al. 2012, fig. 184) by the absence of spikes ( Fig. 201 View FIGURES 198 – 209 ) and from those of N. boibumba (See Abrahim et al. 2012, fig. 231) by the presence of a pointed prolateral prong ( Fig. 210 View FIGURES 210 – 215 ). Females are recognized by the presence of abdominal dorsal denticles ( Fig. 225 View FIGURES 216 – 226 ) and by the book lung margins with rows of cuticular round projections ( Fig. 226 View FIGURES 216 – 226 ).

Description. Male (holotype): total length 2.57. Cephalothorax: carapace orange-brown, broadly oval, pars cephalica slightly elevated, posterolateral surface without spikes, surface and sides smooth; lateral margin without denticles ( Fig. 199 View FIGURES 198 – 209 ); posterior part with one pair of well-developed tubercles ( Fig. 201 View FIGURES 198 – 209 ); recurved set of setae on posterior surface with four small tubercles ( Fig. 201 View FIGURES 198 – 209 ). Clypeus margin slightly reborded, straight in front view, high ( Fig. 200 View FIGURES 198 – 209 ).

Dorsal scutum orangebrown, middle surface and sides smooth, anterior half with projecting denticles ( Fig. 215 View FIGURES 210 – 215 ). Epigastric and postepigastric scutum orange-brown ( Fig. 205 View FIGURES 198 – 209 ). Legs: pale orange. Leg spination: tibia I v4-4 -2; metatarsus I v2-2 - 0. Genitalia: epigastric region with sperm pore small and oval ( Fig. 205 View FIGURES 198 – 209 ). Palp proximal articles, bulb and cymbium pale orange. Embolus without prolateral lamella, with prolateral prong ( Fig. 210 View FIGURES 210 – 215 ), apical process well-developed ( Figs 213–214 View FIGURES 210 – 215 ).

Female (paratype): total length 2.84. Cephalothorax: carapace surface of elevated portion of pars cephalica and sides smooth ( Figs 221, 222 View FIGURES 216 – 226 ). Posterior part with one pair of well-developed tubercles ( Fig. 222 View FIGURES 216 – 226 ). Abdomen: book lung ornate with rows of cuticular projections ( Fig. 226 View FIGURES 216 – 226 ). Dorsal scutum middle surface and sides smooth, anterior half with projecting denticles ( Fig. 225 View FIGURES 216 – 226 ); groove connecting the posterior spiracles bearing pockets ( Fig. 224 View FIGURES 216 – 226 ). Legs spination: femur II v0-2-0; tibia I v4-4 -2; II v6-2 -0; metatarsus I v2-4 -0; II v4-2 -0. Genitalia: atrium narrow ( Fig. 224 View FIGURES 216 – 226 ).
