Figs 72; 75A, D; 107.
Type material. Holotype: COLOMBIA. Caquetá: San José de Fagua, Alto del Río Yurayaco, Secondary forest fragment, Winkler extractor, 1000m [1°20′N, 76°6′W], E. González leg., 7.IX.2000, 1 ♂ (IAvH-I-44). Paratypes: same data as the holotype, 1 ♂ (IAvH-I-645), 1 ♂ (IAvH-I-646).
Etymology. The specific name is a noun in apposition taken from the type locality.
Diagnosis. Males of Tenedos yurayaco sp. n., can be distinguished by bifid retrolateral tibial apophysis (RTA), with thin and pointed anterior branch (aRTA), curved, long posterior branch (pRTA); median apophysis (MA) with concave anterior branch (aMA); very short posterior branch (pMA) (Figs 72C–F; 75A, D).
Description. Male (Holotype, IAvH-I-44). Coloration (Fig. 72A–B): carapace uniformly brown-reddish, dark brown in margins. Chelicerae with paturon brown, fangs brown-reddish. Endites light brown, white on anterior region. Labium and sternum brown. Legs: Coxae I–IV light yellow. Femora I–IV light brown. Patellae I–IV light brown. Tibia I pale yellow, I–IV light brown. Metatarsi-tarsi light brown. Abdomen: dorsally dark gray with seven white guanine spots organized as follows: two small and rounded spots, anteriorly positioned; two lateral spots larger than previous one, anteromedially positioned; two small and rounded spots with an anterior notch, medially positioned; a wide and transversal band, posteriorly positioned. Laterally dark gray with a very wide spot, posteriorly positioned. Ventrally dark gray covered by a large light spot. Spinnerets light brown. Measurements: total length 5.89, carapace length 2.98, width 1.87, height 1.22. Clypeus height 0.62. Eye diameters and interdistances: AME 0.11, ALE 0.13, PME 0.13, PLE 0.15; AME–AME 0.19, AME–ALE 0.24, AME–PME 0.27, PME–PME 0.29, PME–PLE 0.39, ALE–PLE 0.28. Chelicerae 0.91 length. Sternum length 1.23, width 1.10. Legs: I—femur 2.06/ patella 0.68/ tibia 1.99/ metatarsus 2.04/ tarsus 1.34/ total 8.11; II—1.75/ 0.69/ 1.46/ 1.67/ 1.03/ 6.60; III—1.51/ 0.53/ 1.01/ 1.75/ 0.86/ 5.66; IV—1.96/ 0.67/ 1.39/ 2.69/ 1.26/ 4.02. Abdomen length 2.61. Legs spines pattern as general pattern. Palp: retrolateral process of cymbium (RPC) long, wide, widening slightly towards base; tegulum (T) large, rounded, almost as long as wide, retrolateral excavation very accentuated; subtegulum (St) longer than wide; conductor (C) developed, wide with short; appendix (ApC) long, sharp; embolus (E) long, filiform towards apex; base of embolus (EB) with small projection, approximately two times as long as basal tegular membrane; basal tegular membrane (BTM) originated basally on tegulum, ending as very long appendix; spermatic ducts (SD) S-shaped with both folds full opened; ventral tibial apophysis (VTA) very small, tubular, strongly sclerotized; median apophysis (MA) large, bifid, anterior branch (aMA) squared with folded edges, posterior branch (pMA) very short; retrolateral tibial apophysis (RTA) with posterior branch (pRTA) longer than palpal tibia, ventrally projected (Figs 72C–F; 75A, D).
Variation. Males (n=3): total length: 4.88–5.61; carapace length: 2.71–2.98; femur I length: 1.50–2.06.
Distribution. Known from Caquetá department (Fig. 107).
