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 (
