Type material. Holotype: COLOMBIA. Cundinamarca: La Mesa, Inspección La Esperanza, Leaf litter, Winkler extractor, 1100m [4°40’46.73”N, 74°26’47.44”W], A. García & J. Díaz leg., 29.XII.2012, 1 ♂ (ICN-Ar-12336).

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

Diagnosis. Males of Tenedos mesa sp. n., resemble those of T. peckorum Jocqué & Baert, 2002 , T. quipile sp. n., T. guacharos sp. n., and T. henrardi sp. n., by having complex retrolateral tibial apophysis (RTA) (see Jocqué & Baert, 2002: 111, fig. 29A–B; figs 34C–F; 36A–D; 37A–B; 38C–F; 39C–F; 40A–D; 42A–D; 43A–B; 44A–F; 46A–D; 47A–B), but can be distinguished by median apophysis (MA) with straight, short posterior branch (pMA); large retrolateral tibial apophysis, short, squared posterior branch (pRTA); small, rounded projection on embolus base (EB) ( Figs 38C–F ; 40A–B ).

Description. Male (Holotype, ICN-Ar-12336). Coloration ( Fig. 38A–B ): carapace brown, dark brown clypeus and borders. Chelicerae with paturon brown, brown-reddish fangs. Endites and labium light brown, white on anterior region. Sternum brown. Legs: Coxae I–IV white. Femora I–II pale yellow from base to median region, yellow the rest of their extension. Patellae I–IV yellow with small and brown spots. Tibia I pale yellow, II–IV yellow. Metatarsi-Tarsi I–IV yellow. Abdomen: dorsally dark gray with six white guanine spots organized as follows: a large and transversal spot, anteriorly positioned; two oval spots smaller than previous ones, anteromedially positioned; two oval spots larger and oblique with respect to previous one, medially positioned; a large and traversal spot, posteriorly positioned. Laterally dark gray with a wide and oblique stripe, extending to posterior side. Ventrally light gray without spots. Spinnerets yellow. Measurements: total length 4.25, carapace length 2.32, width 1.57, height 1.03. Clypeus height 0.38. Eye diameters and interdistances: AME 0.06, ALE 0.09, PME 0.08, PLE 0.10; AME–AME 0.16, AME–ALE 0.20, AME–PME 0.24, PME–PME 0.21, PME–PLE 0.33, ALE–PLE 0.23. Chelicerae 0.61 length. Sternum length 0.99, width 0.90. Legs: I—femur 1.39/ patella 0.51/ tibia 1.30/ metatarsus 1.36/ tarsus 0.91/ total 5.47; II—1.22/ 0.45/ 0.80/ 0.97/ 0.41/ 3.85; III—1.09/ 0.53/ 0.85/ 1.28/ 0.70/ 4.45; IV—1.45/ 0.53/ 1.29/ 1.81/ 0.95/ 6.03. Abdomen length 1.96. Legs spines pattern (only the differences from the general pattern): I—metatarsus v1r-1r-2; II—tibia v1r-1r-1r; II—femur r0-1-0; IV—metatarsus d1p-1p-0. Palp: retrolateral process of cymbium (RPC) long, wide; tegulum (T) large, rounded, longer than wide, d retrolateral excavation accentuate; subtegulum (St) small, almost as long as wide; conductor (C) wide, sclerotized process short, thin; appendix (ApC) short, apically sharp; embolus (E) long, filiform towards apex; base of embolus (EB) approximately as long as two times as basal tegular membrane width, with small rounded projection; basal tegular membrane (BTM) originated basally on tegulum, proximally flattened, ending as very short sharp appendix; spermatic ducts (SD) S-shaped, both folds full open; ventral tibial apophysis (VTA) short, quadrangular-shaped in ventral view; median apophysis (MA) large, bifid, anterior branch (aMA) squared, posterior branch (pMA) tubular, recurved; retrolateral tibial apophysis (RTA) large, as long as palpal tibia, with both branch overlapping each to other, posterior branch (pRTA) wide with long groove on its extension ( Figs 38C–F ; 40A–B ).

Female. Unknown.

Distribution. Known from Cundinamarca department ( Fig. 107 ).
