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

Diagnosis. Males of Tenedos guacharos sp. n. resemble those of T. peckorum Jocqué & Baert, 2002 , by having similar abdominal spots pattern; bifid median apophysis (MA), quadrangular-shaped, laminar anterior branch (aMA); complex retrolateral tibial apophysis (RTA) (see Jocqué & Baert, 2002: 111, fig. 29A–B; figs 34C–F; 36A–D; 37A–B; 39C–F; 40C–D), but can be distinguished by having anterior branch of retrolateral tibial apophysis (aRTA) longer, apically sharp; sharp basal projection on base of embolus ( Figs 39C–F ; 40C–D ).

Description. Male (Holotype, IAvH-I-2972). Coloration ( Fig. 39A–B ): carapace brown-reddish slightly darker in margins. Chelicerae with paturon base dark brown, fangs brown-reddish. Endites light brown, white on anterior region. Labium and sternum brown. Legs: coxae I–IV light brown. Femora-tarsi I–IV brown with light spots. Abdomen: dorsally dark gray with five white guanine spots organized as follows: two small and rounded spots very close to each other, anteriorly positioned; two rounded spots and smaller than previous ones, medially positioned; one transversal and wide band, posteriorly positioned. Lateral and ventrally dark gray without spots. Measurements: total length 5.08, carapace length 2.78, width 1.65, height 1.22. Clypeus height 0.47. Eye diameters and interdistances: AME 0.11, ALE 0.14, PME 0.12, PLE 0.14; AME–AME 0.19, AME–ALE 0.26, AME–PME 0.29, PME–PME 0.27, PME–PLE 0.27, ALE–PLE 0.28. Chelicerae 0.78 length. Sternum length 1.07, width 0.93. Legs: I—femur 1.72/ patella 0.58/ tibia 1.69/ metatarsus 1.62/ tarsus 1.13/ total 6.74; II—1.37/ 0.61/ 1.28/ 1.22/ 0.73/ 5.21; III—1.31/ 0.58/ 1.18/ 1.31/ 0.64/ 5.02; IV—1.71/ 0.85/ 1.37/ 2.05/ 0.86/ 6.84. Abdomen length 2.21. Legs spines pattern (only the differences from the general pattern): I—metatarsus v1r-1r-2; III—tibia v2-2-2, metatarsus v2-1p-2. Palp: retrolateral process of cymbium (RPC) long, widening towards base, external edge rounded; tegulum (T) large, rounded, longer than wide; subtegulum (St) small, longer than wide in ventral view, external edge small, rounded, rounded ventral projection; conductor (C) developed, wide, with large tubular basal projection; appendix (ApC) long, apically sharp; embolus (E) long, filiform towards apex; base of embolus (EB) approximately as long as three times basal tegular membrane; basal tegular membrane (BTM) originated proximally on tegulum, flattened, ending as very short appendix apically rounded; spermatic ducts (SD) S-shaped with both folds full open, thin; ventral tibial apophysis (VTA) small, short; median apophysis (MA) large, bifid, anterior branch (aMA) squared, laminar, posterior branch (pMA) tubular, short, wide at base; retrolateral tibial apophysis (RTA) very large, complex, consisting of anterior branch (aRTA) very thin, posterior branch (pRTA) wide without apical denticles, curved towards dorsal side ( Figs 39C–F ; 40C–D ).

Female. Unknown.

Distribution. Known from the Huila department, Colombia ( Fig. 107 ).
