Etymology. The specific name refers to the Yuruparí myth, considered fundamental in the traditional culture of some Amazonian groups. It narrates about the origins of the Tenui people, conflicts between its inhabitants and the arrival of Yuruparí (meaning son of the fruit). Currently, this myth constitutes the basis of dances or ceremonies that are celebrated by several indigenous communities settled in the Vaupés department (e.g. Tukanos); noun in apposition.

Diagnosis. Males of N. yurupari sp. nov. resemble those of N. janai sp. nov. ( Figs 39−41 ), N. napo sp. nov. ( Figs 74−76 ) by the palps with tegulum with large triangular RdP, at least 1.5 times longer than wide and E sinuous in the male palps. It is distinguished from N. janai sp. nov. by the bp keel-like, two times wider than long ( Fig. 137 ) (irregularly-shaped, as long as wide with anterior margins depressed in N. janai sp. nov.) and from N. napo sp. nov. by the dRTA bifid ( Figs 137−138 ) (single in N. napo sp. nov.). Females resemble those of N. napo sp. nov. ( Figs 77−79 ) by the MS diamond shaped, anterior to fused part of LL. They are distinguished from the latter species by the fused part of LL extending until almost half EF length and MS two times longer than wide ( Fig. 139 ) (fused part of LL extending until 1/3 of EF length and MS roughly as wide as long in the latter species).

Palp: PTA slightly longer than wide; VTA triangular, displaced retrolaterally; vRTA 1.5 times longer than wide in retrolateral view; dRTA bifid with dorsal branch trapezoidal and ventral branch conical, distally pointed; RdP slightly over 2 times longer than wide ( Figs 129−131 , 136−138 ).

Female (paratype, IAvH-I-3136): Prosoma brown with brown thoracic striae and dark brown margins; cephalic region with longitudinal stripes extending posteriorly from PME and between AME; fovea dark brown; eye borders black. Chelicerae brown, as prosoma. Legs and palps brown, slightly lighter than prosoma. Labium and endites orange brown, distally slightly lighter. Sternum pale orange brown with brown margins. Opisthosoma yellowish brown; dorsally with two pairs of rounded, brown muscle impressions; ventrally with V-shaped lines of muscle impressions. Spinnerets orange brown ( Figs 132−133 ). Total length: 7.11. Prosoma: 2.60 long, 3.00 wide. Opisthosoma: 4.11 long, 2.51 wide. Eyes diameters: 0.23, 0.27, 0.27, 0.30; interdistance: 0.49, 0.49, 0.72, 0.66, 0.65, 0.71.

Spination follows the generic pattern, except femora II−III: r1-0-1; femur IV: p1-1-1, d0-1-1, r0-0-1; tibiae I−II: p1-0-1, r1-0-1, v2-2-0; tibiae III−IV: d1-0-1; metatarsus IV: p1-1-2, r1-1-2, v1-1-2. Epigyne: EF as long as wide; MS with pair of CO situated anteriorly ( Figs 134 , 139 ) Vulva: CD with first winding curving antero-laterad; encapsulated part of internal ducts two times longer than wide, dilated posteriorly; FD antero-laterad ( Figs 135 , 140−141 ).

Variation. Males (n = 3): Total length 5.51−5.99; prosoma length 2.6−3.11; femur I length 4.38−4.75. Females (n = 3): Total length 6.53−7.11; prosoma length 2.60−2.83; femur I length 3.48−4.16.

Distribution. Only known from the type locality ( Fig. 143 ).
