Type material. Holotype: BRAZIL: Pará: ♂, Juruti, Sítio Barroso (-2.4616, -56.0032), 14 August 2006, N.F. Lo Man Hung leg. ( MPEG 8561 View Materials ) GoogleMaps . Paratype: BRAZIL: Pará: 1♂, same locality as for holotype (-2.4643, -56.0024), 8 February 2007, J.A.P. Barreiros leg. ( MPEG 30726 View Materials ) GoogleMaps .

Etymology. The specific name refers to the Juriti bird (genus Leptotila Swaison ), which used to be present in large numbers at the time of the founding of the Juruti municipality; noun in apposition.

Diagnosis. Males of N. juruti sp. nov. resemble those of N. hazzii sp. nov. ( Figs 28−30 View FIGURES 28–33 ), N. nocaima sp. nov. ( Figs 91−93 View FIGURES 91–96 ) and N. tupana sp. nov. ( Figs 121−123 View FIGURES 121–126 ) by the palps with tegulum bearing small, wider than long RdP and E sinuous. They are distinguished from N. tupana sp. nov. by the DTA smooth with no medial projections ( Figs 47−48 View FIGURES 47–49 ) (present in N. tupana sp. nov.); from N. hazzii sp. nov. by the dRTA with ventral branch smaller than dorsal branch ( Fig. 49 View FIGURES 47–49 ) (similar-sized in N. hazzii sp. nov.) and from N. nocaima sp. nov. by the bp rectangular, longer than wide and RdP roughly two times wider than long (bp irregularly-shaped, as wide as long and RdP smaller, more than three times wider than long in N. nocaima sp. nov.). Females are unknown.

Description. Male (holotype): Prosoma orange brown with dark brown margins and brown thoracic striae; cephalic region with brown lines extending posteriorly from PLE, PME and between AME; fovea dark brown; eye borders black. Legs and palps pale brownish orange. Endites pale brownish orange, distally lighter. Labium brown, distally orange brown. Sternum pale range brown with brown margins. Opisthosoma yellowish cream colored; dorsally with small grayish brown marks and two pairs of rounded, brown muscular impressions; ventrally with slightly conspicuous dark gray median longitudinal band and U-shaped lines of muscular impressions. Spinnerets yellowish cream colored, distally lighter ( Figs 42−43 View FIGURES 42–46 ). Total length 6.3. Prosoma: 3.3 long, 3.1 wide. Opisthosoma: 3.0 long, 2.0 wide. Eyes: diameters: 0.22, 0.25, 0.20, 0.30; interdistances: 0.11, 0.04, 0.26, 0.26, 0.26, 0.20. Legs (2143): I: 19.2 (5.0, 1.4, 5.4, 5.2, 2.2); II: 22.6 (5.8, 1.5, 6.5, 6.2, 2.6); III: 15.0 (4.3, 1.2, 4.0, 4.0, 1.5); IV: 18.4 (5.1, 1.1, 4.7, 5.5, 2.0). Palp: PTA, finger-like, as long as wide; VTA reduced, inconspicuous; vRTA roughly 1.5 times longer than wide in retrolateral view; dRTA with two pointed branches, dorsal one roughly three times longer than ventral branch; RdP triangular, distally rounded, two times wider than long; DTA with no projections ( Figs 44−49 View FIGURES 42–46 View FIGURES 47–49 ).

Female: Unknown.

Variation. Males (n = 2): Total length 6.3−6.7; prosoma length 3.1−3.3; femur I length 4.5−5.0.

Distribution. Only known from the type locality, in western Pará, Brazil ( Fig. 142 View FIGURE 142 ).
