Etymology. The specific name refers to Tupana, mother of thunder, revered by the early Indian inhabitants of the region of Borba, before the arrival of the Portuguese Jesuits; noun in apposition.
Diagnosis. Males of N. tupana sp. nov. resemble those of N. hazzii sp. nov. (Figs 28−30), N. juruti sp. nov. (Figs 47−49) and N. nocaima sp. nov. (Figs 91−93) by the palps with tegulum bearing small, wider than long RdP and E sinuous. They are distinguished from the three latter species by the presence of a large median projection on the DTA (Figs 121−122) (DTA without median projection in the other species). Females resemble those of N. nocaima sp. nov. (Figs 94−96) by the epigyne with LL in roughly an inverted T-shape, with pair of elongate COd situated anteriorly. It is distinguished from the latter species by the by the COd J-shaped and separated from each other by almost MS width (Fig. 124) (C-shaped and separated from each other by half MS width in the latter species).
Description. Male (IBSP 8828, paratype): Prosoma brown with darker brown margins and thoracic striae; cephalic region with darker brown stripes extending posteriorly from PME and between AME; fovea dark brown; eye borders black. Chelicerae, legs and palps pale brown. Endites pale orange brown, distally lighter. Labium brown, distally orange brown. Sternum pale yellow with dark orange margins. Opisthosoma pale gray; dorsally with two pairs of brown, rounded muscle impressions; ventrally with faint dark gray longitudinal band and two roughly parallel lines of muscle impressions. Spinnerets pale yellow (Figs 112−113). Total length 6.1. Prosoma: 3.0 long, 2.9 wide. Opisthosoma: 3.0 long, 1.8 wide. Eyes: diameters: 0.22, 0.26, 0.20, 0.28; interdistances: 0.06, 0.02, 0.24, 0.22, 0.20, 0.20. Legs (2143): I: 19.7 (4.9, 1.4, 5.5, 5.4, 2.5); II: 23.2 (5.6, 1.5, 6.7, 6.6, 2.8); III: 15.5 (4.1, 1.2, 4.0, 4.6, 1.6); IV: 18.7 (4.9, 1.2, 4.8, 5.5, 2.3). Palp: PTA roughly squared, distally rounded, as wide as long; VTA reduced, absent; vRTA two times longer than wide; dRTA with two pointed branches, the dorsal one two times longer than ventral one; tegulum with RdP roughly 1.5 times wider than long; bp subsquared, as wide as long (Figs 114−116, 121−123).
Female (IBSP 8828, paratype): Coloration pattern as in male except prosoma, with brown reticulated pattern laterally and brown marks between thoracic striae (Figs 117−118). Total length 6.7. Prosoma: 2.6 long, 2.7 wide. Opisthosoma: 3.8 long, 2.4 wide. Eyes: diameters: 0.21, 0.27, 0.20, 0.30; interdistances: 0.10, 0.03, 0.26, 0.28, 0.27, 0.24. Epigyne: EF slightly wider than long; LL fused; pair of elongate COd situated anteriorly bearing posterior CO; MS situated posteriorly to fused part of LL, trapezoidal, almost three times wider than long (Figs 119, 124). Vulva: CD with first winding laterad; encapsulated part of internal ducts two times longer than wide, slightly more dilated posteriorly; FD antero-laterad (Figs 120, 125−126).
Variation. Males (n = 9): Total length 5.6−6.7; prosoma length 2.5−3.3; femur I length 4.6−4.9. Females (n = 10): Total length 5.5−7.8; prosoma length 2.5−3.2; femur I length 3.1−3.8.
