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.

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.
