Norte de Santander: Cucutilla, Vereda Carrizal, Sector Sisavita, Quebrada Poveda, Secondary forest Secondary forest dominated by Quercus humboldti, Pitfall trap, 2040-2200m, [7°28′28′′N, 72°50′11′′W], E.

Etymology. The specific epithet is a patronymic in honor of the arachnologist Pakawin Dankittipakul by his contributions to the taxonomy and systematic of the ant-eating spiders.
Diagnosis. Tenedos dankittipakuli sp. n. resembles T. griswoldi sp. n., T. tama sp. n., T. humboldti sp. n., and T. piedecuesta sp. n., by wide retrolateral tibial apophysis (RTA); large median apophysis (MA) with thin anterior branch (aMA) (Figs 77A–D; 78A–B; 80A–D; 82A–D; 83A–B; 85A–D; 86A–B; 88A–D; 80A–B; 91A–D; 92A–B), but are distinguished by reduced anterior branch of the retrolateral tibial apophysis (aRTA), shorter posterior branch (pRTA); median apophysis with very short and thin appendix at anterior side (Figs 77A–D; 78A–B; 80A–D). Females are similar those of Tenedos tama sp. n., T. humboldti sp. n., and T. piedecuesta sp. n. by very wide at base seminal receptacles (SR), slightly curved towards median septum (Figs 77E–F; 78C–D; 80E–F; 85E–F; 86C–D; 88E–F; 89C–D; 91E–F; 92C–D), but are characterized by large median field plate (MFP); very wide seminal receptacles (SR) at sub-distal region (Figs 77E–F; 78C–D; 80E–F).

Tibia I pale yellow with brown patches on basal and distal sides, II–IV, brown. Metatarsus I pale yellow with brown patches on basal and distal sides, II–IV brown. Tarsi I–IV light brown. Abdomen: dorsally dark gray with six white guanine spots organized as follows: two transversal spots with an anterior notch, medially positioned; two irregular spots smaller than previous ones, in posteromedial position; two transversal and large bands, posteriorly positioned.

Variation. Males (n=8): total length: 5.26–6.02; carapace length: 2.90–3.02; femur I length: 1.93–2.01. Some specimens of Tenedos dankittipakuli sp. n. exhibit morphological variation such as spots number on abdomen, the size and shape of the median apophysis and retrolateral tibial apophysis (Fig. 80A–D).
Distribution. Known from Norte de Santander department (Fig. 106).
