Type material. Holotype: COLOMBIA. Valle del Cauca: La Cumbre, Vereda Chicoral Alto Bitaco, Bitaco , Finca Monte Bello , pristine forest fragment, pitfall trap, 2030 m, [3°33′56″N, 76°34′58″W], I. Quintero & González leg., 2-4.VIII.2003, 1 ♁ (IAvH-I-6128) . Paratypes: same data as the holotype, 1 ♀ (IAvH-I-6129), 1 ♁ 1 ♀ (IAvH-I- 6130), 1 ♀ (IAvH-I-6132), 1 ♀ (IAvH-I-6133), 1 ♀ (IAvH-I-6131) .

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

Diagnosis. Males of Tenedos valle sp. n. resembles those of Tenedos huila sp. n. Tenedos huila sp. n. by having a developed basal tegular membranous projection (BTM); sclerotized process at distal side of the conductor (C) ( Figs 34 , 35A–D ; 36A–B ), but are distinguished by recurved median apophysis (MA) with anterior tip; thinner posterior branch of the retrolateral tibial apophysis (pRTA), and sub-quadrangular anterior branch (aRTA), apically entire ( Figs 38A–D ; 39A–B ). Females are similar those of Tenedos huila sp. n. by shape of lateral borders (LB) and atrium (A), are characterized by wider copulatory ducts (CD), describing less than five tuns on spermathecae ( Figs 38E–F ; 39C–D ).

Description. Male (Holotype, IAvH-I-6128). Coloration ( Fig. 37A–B ): carapace brown-orange, dark brown in margins. Chelicerae with brown paturon, fangs brown-reddish. Endites pale brown, white on anterior region. Labium and sternum light brown, with dark borders. Legs: Coxae I–IV pale yellow. Femora I–IV brown with dark patches on medial region. Patellae I–IV brown. Tibia-tarsi I–IV light brown. Abdomen: dorsally dark gray with twelve white guanine spots organized as follows: two large, slightly elongated spots, followed by two incipient, irregular, very small spots, anteriorly positioned; six transverse spots, which the medial are smaller, medially positioned; two irregular spots smaller than previous ones, medially fused, posteriorly positioned. Laterally dark gray with a white band apically divided. Ventrally beige with gray lateral patches. Spinnerets light brown.

Palp: retrolateral process of cymbium (RCP) strongly sclerotized at basal side; tegulum (T) apically longer than wide, sub-rounded, elongated towards embolus base with developed basal membrane; subtegulum (St) thin in ventral view; conductor (C) with sclerotized process at distal side, prolateral laminar projection projected; appendix (ApC) very short, pointed; embolus (E) emerging basally on tegulum tending towards prolateral side; embolus base (EB) robust, short; spermatic ducts visible in retrolateral view, thin; ventral tibial apophysis (VTA) small, robust, tubular-shaped in ventral view; median apophysis (MA) large, sub-quadrangular; retrolateral tibial apophysis (RTA) with posterior branch (pRTA) longer than palpal tibia, thin ( Figs 38A–D ; 39A–B ).

Female (Paratype, IAvH-I-6129). Coloration and abdominal pattern of spots as male with some modifications: carapace uniformly brown, legs light brown ( Fig. 37C–D ). Measurements: total length 4.29, carapace length 1.84, width 1.24, height 0.91. Clypeus height 0.37. Eye diameters and interdistances: AME 0.07, ALE 0.08, PME 0.07, PLE 0.07; AME–AME 0.15, AME–ALE 0.19, AME–PME 0.21, PME–PME 0.21, PME–PLE 0.28, ALE–PLE 0.17. Chelicerae 0.66 length.
