Type Material: Holotype: COLOMBIA: Cundinamarca: ♂, Nocaima, Casa de Oscar (5.0672, -74.3831), 188 m, 6 June 2022, O. Enciso leg. ( MPUJ _ ENT0086707 ) GoogleMaps . Paratypes: COLOMBIA: Cundinamarca: 3 ♀, same locality as for holotype, 6 June 2022, O. Enciso leg. ( MPUJ _ ENT0086708 ); GoogleMaps 2 ♂, same locality as for holotype, 6 June 2022, O. Enciso leg. ( MPUJ _ ENT0086706 ) GoogleMaps .

Etymology. The specific name refers to the municipality of Nocaima, type locality of the new species and hometown of Oscar Enciso, a self-taught and passionate naturalist who collected the specimen; noun in apposition.

Diagnosis. Males of N. nocaima sp. nov. resemble those of N. hazzii sp. nov. ( Figs 28−30 View FIGURES 28–33 ), N. juruti sp. nov. ( Figs 47−49 View FIGURES 47–49 ) and N. tupana sp. nov. ( Figs 119−121 View FIGURES 117–120 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 91−92 View FIGURES 91–96 ) (present in N. tupana sp. nov.); from N. hazzii sp. nov. by the dRTA with ventral branch smaller than dorsal branch ( Fig. 93 View FIGURES 91–96 ) (similar-sized in N. hazzii sp. nov.) and from N. juruti sp. nov. by the bp irregularly-shaped, as wide as long and RdP smaller, more than three times wider than long ( Fig. 92 View FIGURES 91–96 ) (bp rectangular, longer than wide and RdP roughly two times wider than long in N. juruti sp. nov.). Females resemble those of N. tupana sp. nov. ( Figs 124−126 View FIGURES 121–126 ) 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 C-shaped and separated from each other by half MS width ( Fig. 94 View FIGURES 91–96 ) (COd J-shaped and separated from each other by almost MS width in the latter species).

Description. Male (holotype): Prosoma pale yellowish brown with brown margins and grayish-brown lines along thoracic striae and extending posteriorly from behind AME, PME and PLE; fovea orange brown; eye borders black. Chelicerae, legs and palps pale yellowish brown. Sternum cream colored with brownish-orange margins. Labium orange brown, slightly lighter distally. Endites pale yellowish cream colored. Opisthosoma pale gray; dorsally with whitish cardiac mark and two pairs of brown muscle impressions; ventrally with two parallel lines of muscle impressions; spinnerets cream colored ( Figs 82−83 View FIGURES 82–86 ). Total length 7.03. Prosoma: 3.25 long, 3.17 wide. Opisthosoma: 3.39 long, 2.04 wide. Eyes: diameters: 0.24, 0.28, 0.25, 0.29; interdistances: 0.47, 0.43, 0.68, 0.62, 0.65, 0.66. Legs (2143): I: 18.53 (4.75, 1.52, 5.57, 4.79, 1.90); II: 21.60 (5.56, 1.61, 6.42, 5.81, 2.20); III: 14.22 (4.08, 1.18, 3.87, 3.68, 1.41); IV: 17.64 (4.84, 1.10, 4.61, 5.19, 1.90). Spination follows the generic pattern, except tibiae III-IV: d1-0-1; metatarsus III: v2-2-0. Palp: PTA roughly rectangular, two times longer than wide; VTA triangular, retrolaterally displaced; vRTA 1.5 times longer than wide in retrolateral view; dRTA bifid with dorsal branch 1.5 times larger than ventral branch; tegulum with RdP small, barely conspicuous, three to four times wider than long; bp irregularly-shaped, roughly as wide as long; DTA without projections ( Figs 84−86 View FIGURES 82–86 , 91−93 View FIGURES 91–96 ).

Female (paratype): Coloration pattern as in male, slightly darker. Legs with faint gray marks at the base of spines ( Figs 87−88 View FIGURES 87–90 ). Total length 7.88. Prosoma: long, 3.08 wide. Opisthosoma: 4.61 long, 3.53 wide. Eyes: diameters: 0.20, 0.23, 0.20, 0.32; interdistances: 0.47, 0.48, 0.69, 0.64, 0.65, 0.67. Legs (1243) I: 18.22 (4.61, 1.46, 5.58, 4.68, 1.89); II: 14.30 (4.04, 1.43, 4.18, 3.33, 1.32); III: 10.77 (3.16, 1.15, 2.87, 2.56, 1.03); IV: 12.56 (3.66, 1.12, 3.22, 3.20, 1.36). Spination follows the generic pattern, except femur III: r1-0-1; patella: d0-0-1; tibia: d1-0- 1. Epigyne: EF slightly longer than wide; LL fused; pair of elongate COd with CO situated posteriorly; MS small, triangular, two times longer than wide ( Figs 89 View FIGURES 87–90 , 94 View FIGURES 91–96 ). Vulva: CD with first winding gently curving antero-laterad; encapsulated part of internal ducts two times longer than wide, slightly more dilated posteriorly; FD anteriad ( Figs 90 View FIGURES 87–90 , 95−96 View FIGURES 91–96 ).

Variation. Males (n = 3): Total length 6.81−7.03; prosoma length 2.98−3.25; femur I length 4.75−5.10. Females (n = 3): Total length 6.87−7.88; prosoma length 3.02−3.08; femur I length 3.48−4.11.

Distribution. Only known from the type locality in Colombia ( Fig. 143 View FIGURE 143 ).
