Type material. Holotype: COLOMBIA. Putumayo: Territorio Cofán, Leaf litter, Winkler extractor, 1430m [1º4′4.46′′N, 76º43′27.05′′W], E. González leg., 24.IX.1998, 1 ♂ (ICN-Ar-12915). Paratypes: same data as the holotype 1 ♀ (ICN-Ar-12916).
Etymology. The specific name is a noun in apposition taken from the type locality.
Diagnosis. Males of Tenedos cofan sp. n. are characterized by shape of median apophysis (MA) with small sub-apical projection, small, complex retrolateral tibial apophysis (RTA), forming concavity with irregular anterior edges; very short basal retrolateral tibial apophysis (bRTA), apically pointed (Figs 52A–D; 53A–B). Females are characterized by the epigyne provided with two anterolateral arches overhanging an oval medial field plate (MFP), and by short seminal receptacles (SR) curved towards median septum of epigyne (Figs 52E–F; 53C–D).
Description. Male (Holotype, ICN-Ar-12317). Coloration (Fig. 51A–B): carapace orange, dark brown in margins. Chelicerae with paturon brown, fangs brown-reddish. Endites light brown, white on anterior region. Labium and sternum light brown. Legs: Coxae I–IV pale yellow. Femora-tarsi I–IV brown. Abdomen: dorsally dark gray with five white guanine spots organized as follows: two irregular spots very close to each other with an anterior notch, anteriorly positioned; two sub-rounded spots larger than previous ones, anteromedially positioned; a transversal and wide band, posteriorly positioned. Lateral and ventrally pale beige without spots. Spinnerets light brown. Measurements: total length 3.65, carapace length 1.73, width 1.15, height 0.89. Clypeus height 0.33. Eye diameters and interdistances: AME 0.07, ALE 0.09, PME 0.10, PLE 0.11; AME–AME 0.14, AME–ALE 0.16, AME–PME 0.25, PME–PME 0.20, PME–PLE 0.25, ALE–PLE 0.24. Chelicerae 0.68 length. Sternum length 0.77, width 0.75. Legs: I—femur 1.19/ patella 0.42/ tibia 1.33/ metatarsus 1.11/ tarsus 0.85/ total 4.90; II—1.08/ 0.44/ 0.89/ 0.90/ 0.82/ 4.13; III—1.05/ 0.48/ 0.63/ 0.68/ 0.64/ 3.48; IV—1.25/ 0.40/ 0.95/ 1.28/ 0.78/ 4.66. Abdomen length 1.62. Legs spines pattern (only the differences from the general pattern): I—metatarsus v1r-0-2; III—tibia v1p-1p-2, v2- 0-2; IV—metatarsus v2-1p-2. Palp: retrolateral process of cymbium (RPC) long, wider at base; tegulum (T) large, rounded, almost as long as wide, retrolateral excavation very accentuated; subtegulum (St) large, longer than wide; conductor (C) developed, wide, with short, very wide sclerotized region on distal side; 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; basal tegular membrane (BTM) originated proximally on tegulum, proximally flattened, ending as a very short appendix; spermatic ducts (SD) S-shaped thin with both folds full open; ventral tibial apophysis (VTA) short, quadrangular-shaped in ventral view; median apophysis (MA) large, squared with small projection on sub-distal side; retrolateral tibial apophysis (RTA) bifid, small, shorter than palpal tibia (Figs 52A–D; 53A–B).
Female (Paratype, ICN-Ar-12916). Coloration and abdominal pattern of spots as male with the following exceptions: carapace uniformly brown, abdomen with two additional small spots, medially positioned, and spinnerets light yellow (Fig. 51C–D). Measurements: total length 3.66, carapace length 1.68, width 1.08, height 0.74. Clypeus height 0.30. Eye diameters and interdistances: AME 0.07, ALE 0.09, PME 0.09, PLE 0.08; AME–AME 0.08, AME–ALE 0.16, AME–PME 0.21, PME–PME 0.20, PME–PLE 0.25, ALE–PLE 0.26. Chelicerae 0.63 length. Sternum length 0.64, width 0.65. Legs: I—femur 0.82/ patella 0.47/ tibia 0.62/ metatarsus 0.64/ tarsus 0.67/ total 3.22; II—0.95/ 0.40/ 0.57/ 0.60/ 0.50/ 3.02; III—0.88/ 0.31/ 0.60/ 0.39/ 0.44/ 2.62; IV—1.06/ 0.31/ 0.70/ 0.77/ 0.63/ 3.47. Abdomen length 1.76. Legs spines pattern (only the differences from the general pattern): I—tibia v1-r-1r-2, metatarsus v1r-0-2; II—metatarsus v1r-0-2; III—metatarsus v2-0-2; IV—metatarsus v2-1p-2. Epigyne: lateral borders long and curved towards posteromedial region of epigyne, forming large, medial atrium with two anterolateral arches; median field plate large wider than long and oval-shaped; copulatory ducts very short, wide, almost undistinguished from spermathecae; seminal receptacles short, wide, curved towards median septum; spermathecae large, irregulars, posteriorly positioned; fertilization ducts almost as long as spermathecae length (Figs 52E–F; 53C–D).
Variation. Males (n=2): total length: 3.65–3.70; carapace length: 1.65–1.73; femur I length: 1.19–1.30.
Distribution. Known from Putumayo department (Fig. 107).
