Other material examined. COLOMBIA. Valle del Cauca, La Cumbre, Finca Monte Bello, Alto Bitaco, Vereda Chicoral, Corregimiento Bitaco, pristine forest, pitfall trap, 2115 m, (03°34′08′′N, 76°35′19′′W), 23-25.VII.2003, I. Quintero, E. González leg., 1♁ (IBSP 324938).

Etymology. The specific epithet is a noun in apposition to the type locality of the species.

Diagnosis. Males of Tenedos cumbre sp. n. are similar to those of T. trilobatus Jocqué & Baert 2002, by having a small conductor (C) and cymbium (Cy) (Figs 10A–E; 12A–D; 13A–B; 14, 15A–D), but can be distinguished by having posterior branch of the retrolateral tibial apophysis (pRTA) longer than palpal tibia; laminar, longer median apophysis (MA) with short anterior tip (Figs 17A–D; 18A–B). Females are similar those of Tenedos trilobatus by short copulatory ducts (SD) and relatively similar shaped of lateral borders (LB) (Figs 10F; 12E–F), are distinguished by longer, copulatory ducts (CD), describing almost two coils on spermathecae and by having a delimited, m-shaped atrium (A) (Figs 17E–F; 18C–D).

Description. Male (IAvH-I-6105). Coloration (Fig. 16A–B): carapace uniformly reddish-brown with slightly dark in margins, lighter in posterior region of fovea. Chelicerae with dark brown paturon, brown-reddish fangs. Endites light brown, anteriorly white. Labium and sternum brown, medially lighter. Legs: Coxae-tarsi I–IV light yellow, tarsi darker. Abdomen: dorsally dark gray with eight white guanine spots organized as follows: two small, thin, elongated spots, anteriorly positioned; four subrounded spots larger than previous ones, with anterior notch, medially positioned; two small, irregular spots partially joined in medial region, posteriorly positioned. Laterally dark gray with a long and wide spot. Ventrally beige. Spinnerets pale yellow. Measurements: total length 5.08, carapace length 2.46, width 1.52, height 0.99. Clypeus height 0.39. Eye diameters and interdistances: AME 0.08, ALE 0.09, PME 0.11, PLE 0.11; AME–AME 0.17, AME–ALE 0.19, AME–PME 0.16, PME–PME 0.23, PME–PLE 0.32, ALE–PLE 0.23. Chelicerae 0.74 length. Sternum length 0.99, width 0.86. Legs: I—femur 1.73/ patella 0.50/ tibia 1.43/ metatarsus 1.34/ tarsus 1.06/ total 6.06; II—1.44/ 0.53/ 1.19/ 1.23/ 0.84/ 5.23; III—1.37/ 0.62/ 0.97/ 1.33/ 0.79/ 5.08; IV—1.69/ 0.63/ 1.47/ 2.08/ 0.86/ 6.73. Abdomen length 2.12. Legs spines pattern (only the differences from the general pattern): I—tibia v 2-2-2, metatarsus v 2-1p-2, p 0-0-1v. Palp: retrolateral process of cymbium (RPC) short, projected; tegulum (T) anteriorly rounded, elongated towards embolus base; subtegulum (St) distinguishable as thin region in ventral view; conductor (C) small, with prolateral laminar region moderately developed; appendix (ApC) short, apically sharp; embolus (E) wide in the base, filiform towards apex; embolus base (EB) robust, prolaterobasally projected; spermatic ducts (SD) very thin, recurved, slightly curved in medial side (ventral view); ventral tibial apophysis (VTA) short, quadrangular-shaped; median apophysis (MA) long, with slightly wide base; retrolateral tibial apophysis with long posterior branch (pRTA), anterior branch (aRTA) short, knife-shaped (Figs 17A–D; 18A–B).

Female (IAvH-I-6106). Coloration and abdominal pattern of spots as male, more pigmented, carapace dark-brown and legs uniformly brown, but white coxae (Fig. 16C–D). Measurements: total length 5.39, carapace length 2.54, width 1.63, height 1.14. Clypeus height 0.46. Eye diameters and interdistances: AME 0.08, ALE 0.11, PME 0.10, PLE 0.12; AME–AME 0.17, AME–ALE 0.23, AME–PME 0.25, PME–PME 0.27, PME–PLE 0.35, ALE– PLE 0.27. Chelicerae 0.83 length. Sternum length 0.94, width 0.87. Legs: I—femur 1.42/ patella 0.49/ tibia 1.25/ metatarsus 1.10/ tarsi 0.86/ total 5.12; II—1.21/ 0.59/ 1.03/ 0.94/ 0.58/ 4.35; III—1.19/ 0.54/ 0.84/ 0.98/ 0.62/ 4.17; IV—1.56/ 0.58/ 1.20/ 1.77/ 0.85/ 5.96. Abdomen length 2.51. Legs spines pattern (only the differences from the general pattern): I—tibia v 2-1r-1p, metatarsus r 0-0-1v; II—femur p 0-0-1d. Epigyne: lateral borders (LB) short, strongly sclerotized; median field plate (MFP) very small; copulatory ducts (CD) long, describing at least 2 coils on spermathecae; spermathecae (S) large, irregulars, posteriorly positioned; fertilization ducts (FD) longer than spermathecae (Figs 17E–F; 18C–D).

Variation. Males (n=7): total length: 4.48–5.08; carapace length: 2.39–2.46; femur I length: 1.47–1.73.

Distribution. Known from Valle del Cauca department (Fig. 45).
