Type material. Holotype: COLOMBIA. Caldas: Pensilvania, Sitio Berlin, Secondary forest , Pitfall trap, 2750m [5°21′08″N, 75°11′10″W], E. González, L. Arango & J. M. Montes leg., 24-26.VII.2004, 1 ♂ (IAvH-I-2973).

Etymology. The epithet is a noun in apposition honoring to the Marquetones, indigenous people who lived in the Caldas department.

Diagnosis. Males of Tenedos marquetones sp. n., resemble those of T. pensilvania sp. n., by wide retrolateral tibial apophysis (RTA); large median apophysis (MA); basal tegular membrane (BTM) flattened at proximal side ( Figs 73C–F ; 74C–F ; 75A–B, D–E ), but are distinguished by bifid median apophysis with squared-shaped anterior branch, short posterior branch; thinner apically tapered retrolateral tibial apophysis with apical denticles ( Figs 73C–F ; 75B–E ).

Description. Male (Holotype, IAvH-I-2973). Coloration ( Fig. 73A–B ): carapace uniformly dark brown. Chelicerae with paturon brown, fangs brown-reddish. Endites brown, white on anterior region. Labium and sternum light brown. Legs: Coxae I–IV light yellow. Femora I–IV with base brown, white on medial region and distally brown. Patellae dark brown. Tibiae-metatarsi I–IV medially pale yellow and dark brown on basal and distal regions. Tarsi I–IV dark brown. Abdomen: dorsally dark gray with five white guanine spots organized as follows: two elongated spots, anteriorly positioned; two oval spots smaller than previous ones, medially positioned; a very large and rounded spot, posteriorly positioned. 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 6.70, carapace length 3.29, width 1.83, height 1.48. Clypeus height 0.58. Eye diameters and interdistances: AME 0.10, ALE 0.12, PME 0.11, PLE 0.17; AME–AME 0.25, AME–ALE 0.31, AME–PME 0.35, PME–PME 0.31, PME–PLE 0.47, ALE–PLE 0.30. Chelicerae 1.19 length. Sternum length 1.08, width 1.01. Legs: I—femur 2.04/ patella 0.74/ tibia 1.85/ metatarsus 1.55/ tarsus 1.16/ total 7.34; II—1.73/ 0.76/ 1.52/ 1.29/ 0.87/ 6.17; III—1.70/ 0.73/ 1.23/ 1.43/ 0.87/ 5.97; IV—2.02/ 0.87/ 1.64/ 2.20/ 1.12/ 8.05. Abdomen length 3.14. Legs spines pattern (only the differences from the general pattern): I—femur d0-0-1, tibia v1r-1r-2, metatarsus v2-1r-2; II—femur=I, tibia v1r-1r-1r, p0-0-1d, metatarsus v2-2-2, p0-0-1d, III-IV—femur d0-0-1, metatarsus v2-2-2. Palp: retrolateral process of cymbium (RPC) long, widening towards base; tegulum (T) rounded; subtegulum (St) large, longer than wide in ventral view; conductor (C) large, with short, thin sclerotized region on distal side; appendix short, apically sharp; embolus (E) long, filiform towards apex; base of embolus (EB) approximately as long as basal tegular membrane; basal tegular membrane (BTM) wide, originated basally on tegulum, reticulated, with reduced appendix; spermatic ducts (SD) S-shaped, short, wide, with both folds full open; ventral tibial apophysis (VTA) very short, anteriorly projected; median apophysis (MA) large, bifid, with large and squared anterior branch (aMA), posterior branch (pMA) short and tubular; retrolateral tibial apophysis (RTA) large, wide at base, apically sharp, shorter than palpal tibia ( Figs 73C–F ; 75B–E ).

Female. Unknown.

Distribution. Known from Caldas department ( Fig. 107 ).
