Type material. Holotype: COLOMBIA. Valle del Cauca: Buenaventura, Punta San Pedro, Reserva Natural San Pedro , Pristine forest fragment, Winkler extractor, 35m [3°49′48″N, 77°15′0″W], D. Martínez, F. Cala, G. Galvis & S. Galvis leg., 8-13.VII.2017, 1 ♂ (ICN-Ar-10934) GoogleMaps . Paratypes: same data as the holotype, 1 ♀ (ICN-Ar-12318), 1 ♀ (ICN-Ar-12319) GoogleMaps .

Etymology. The specific name is a noun in apposition taken from the type locality.

Diagnosis. Males of Tenedos choco sp. n., can be recognized by their large, bifid retrolateral tibial apophysis (RTA), very large posterior branch (pRTA), curved towards dorsal side, apically bifid; thin, apically squared anterior branch (aRTA); large, bifid median apophysis (MA), short anterior branch (aMA); flattened, rounded posterior branch (pMA); very long embolus (E), forming arc at prolateral side; robust, very wide ventral tibial apophysis (VTA) ( Figs 29A–D View FIGURE 29 ; 30A–B View FIGURE 30 ). Females are characterized by thin lateral borders (LB), posteriorly positioned; very long seminal receptacles, describing C-shaped; longer than wide medial field plate, straight at basal edge ( Figs 29E–F View FIGURE 29 ; 30C–D View FIGURE 30 ).

Description. Male (Holotype, ICN-Ar-10934). Coloration ( Fig. 28A–B View FIGURE 28 ): carapace light brown-reddish, aspect granulate, dark brown in borders, two dark brown elongated spots in front fovea. Chelicerae with paturon brown and brown-reddish fangs. Endites pale yellow, white on anterior region. Labium brown. Sternum dark brown. Legs: Coxae I–II white, III–VI light brown. Femora I–II light brown, white on basal and distal regions, III–IV yellow. Patellae I–II light brown, III–IV yellow. Tibia I light yellow, II–IV yellow, with brown spots on prolateral and retrolateral sides. Metatarsi I–IV yellow. Tarsi I–IV white, basally yellow in color. Abdomen (observed in an immature male): dorsally dark gray with eight white guanine spots organized as follows: two small and rounded spots, anteriorly positioned; two rounded spots, larger than previous one, sub-medially, positioned; two large spots with a lightly notch at anterior side, medially positioned; two small spots, medially joined by thin stripe, posteriorly positioned. Laterally dark gray with a wide and light oblique stripe. Ventrally light gray without spots. Spinnerets light brown. Measurements: total length 4.62, carapace length 2.47, width 1.46, height 1.08. Clypeus height 0.54. Eye diameters and interdistances: AME 0.08, ALE 0.09, PME 0.11, PLE 0.13; AME–AME 0.18, AME–ALE 0.21, AME–PME 0.23, PME–PME 0.26, PME–PLE 0.35, ALE–PLE 0.26.

Abdomen length 1.99. Legs spines pattern (only the differences from the general pattern): I—tibia v1r-1r-2; II—tibia v1r-1r-1r, metatarsus v1r-1r-2; III—femur r0-1-0. Palp: retrolateral process of cymbium (RPC) long, narrow, widening slightly towards base; tegulum (T) large, rounded, longer than wide, retrolateral concavity few accentuated; subtegulum (St) longer than wide, displaced towards inferior side by large conductor; conductor (C) very developed, wide, curly at distalprolateral side, anteriorly projected; appendix (ApC) long, wide, distally flattened; base of embolus (EB) as two times as long as basal tegular membrane; basal tegular membrane (BTM) poorly developed, originated basally on tegulum, ending as very short appendix; spermatic ducts (SD) S-shaped, both folds full opened and thin; ventral tibial apophysis (VTA) large, strongly sclerotized; median apophysis (MA) very large, wide, bifid, both branch acuminated, posterior branch (pMA) longer, wider than posterior; retrolateral tibial apophysis (RTA) longer than palpal tibia, large, bifid ( Figs 29A–D View FIGURE 29 ; 30A–B View FIGURE 30 ).

Female (Paratype, ICN-Ar-12318). Coloration ( Fig. 28C–D View FIGURE 28 ): carapace uniformly dark brown. Chelicerae with paturon brown and brown-reddish fangs. Endites brown, yellow on anterior region. Labium and sternum brown. Legs: Coxae I–IV light brown. Femora-tarsi I–IV brown. Abdomen coloration and guanine spots pattern as male.
