Type material. Holotype: COLOMBIA. Caldas: Pensilvania, Finca La Cabaña, Secondary forest , Pitfall trap, 2650m [5°22′05″N, 75°10′12″W], E. González, L. Arango & J. M. Montes leg., 30.VII-1.VIII.2004, 1 ♂ (IAvH-I-657) . Paratypes: same data as the holotype 1 ♂ (IAvH-I-658) .

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

Diagnosis. Males of Tenedos pensilvania sp. n., can be distinguished by concave median apophysis (MA) with hook-shaped appendix, anterior branch of retrolateral tibial apophysis (aRTA) represented by thin lamina, and by the presence of short and wide basal retrolateral tibial apophysis (bRTA) ( Figs 74C–F ; 75C, F ).

Description. Male (Holotype, IAvH-I-657). Coloration ( Fig. 74A–B ): carapace uniformly dark brown, dark brown in margins. Chelicerae with paturon brown, fangs brown-reddish. Endites brown, white on anterior region. Labium and sternum brown. Legs: Coxae I–IV light yellow. Femora I–IV with brown rings in basal and distal regions, medially white. Patellae-tibiae I–IV dark brown, tibia I pale yellow, brown on basal and distal regions. Metatarsus I pale yellow, I–IV light brown, dark brown o basal and distal regions. Tarsi I–IV dark brown. Abdomen: dorsally dark gray with a small scutum and nineteen white guanine spots organized as follows: two large and elongated spots, anteriorly positioned; two irregular spots smaller than previous ones, sub-medially positioned; fifteen irregular and small spots, organized as parallels groups of three spots, positioned from the medial region to posterior side. Laterally dark gray without spots. Ventrally dark gray with small spots on lateral sides and a long and wide central spot. Spinnerets light brown. Measurements: total length 6.25, carapace length 3.21, width 2.34, height 1.51. Clypeus height 0.69. Eye diameters and interdistances: AME 0.12, ALE 0.14, PME 0.15, PLE 0.18; AME–AME 0.24, AME–ALE 0.27, AME–PME 0.35, PME–PME 0.34, PME–PLE 0.49, ALE–PLE 0.30. Chelicerae 1.01 length. Sternum length 1.26, width 1.25. Legs: I—femur 2.10/ patella 0.75/ tibia 1.81/ metatarsus 1.49/ tarsus 1.20/ total 7.35; II—1.69/ 0.81/ 1.45/ 1.27/ 0.84/ 6.06; III—1.33/ 0.59/ 1.01/ 1.28/ 0.87/ 5.08; IV—1.47/ 0.62/ 1.60/ 2.08/ 1.01/ 6.78. Abdomen length 2.52. Legs spines pattern (only the differences from the general pattern): I—tibia v1r-1r-2, metatarsus v1r-1r-2; II—tibia v1r-1r-1r, metatarsus v1r-0-2. Palp: retrolateral process of cymbium (RPC) long, widening towards base; tegulum (T) rounded; subtegulum (St) large, almost as long as wide, globose in ventral view; conductor (C) large, with short, thin sclerotized region on distal side; appendix (ApC) short, apically sharp; embolus (E) long, laminar at base, filiform towards apex; base of embolus (EB) approximately as long as two times as basal tegular membrane; basal tegular membrane (BTM) wide, originated basally on tegulum, reticulated, ending as an very short, apically rounded; spermatic ducts (SD) S-shaped, short, wide with both folds full open and straight; ventral tibial apophysis (VTA) very short, anteriorly projected; median apophysis (MA) large, concave, strongly sclerotized with rounded tips; retrolateral tibial apophysis (RTA) large, wide, apically bifid, almost as long as palpal tibia ( Figs 74C–F ; 75C, F ).

Female. Unknown.

Distribution. Known from Caldas department ( Fig. 106 ).
