Figs 80−96

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

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 ), N. juruti sp. nov. ( Figs 47−49 ) and N. tupana sp. nov. ( Figs 119−121 ) 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 ) (present in N. tupana sp. nov.); from N. hazzii sp. nov. by the dRTA with ventral branch smaller than dorsal branch ( Fig. 93 ) (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 ) (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 ) 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 ) (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 ).

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 , 91−93 ).

Female (paratype): Coloration pattern as in male, slightly darker. Legs with faint gray marks at the base of spines ( Figs 87−88 ). 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 , 94 ). 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 , 95−96 ).

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 ).
