Tenedos andes Jocqué & Baert, 2002: 83–84, figs 7A–C. (Male holotype from Finca San Pablo, 3km de N Alban, Cundinamarca, Colombia, 1800m, P. & B. Wygodzinsky leg., deposited in AMNH_ IZC 00217585, examined).
Other material examined. COLOMBIA. Cundinamarca: Topaipí, Finca El Alirio, Corn crop, Manual, 1377m [5°24,055’N, 74°17.64’W], M. Medrano & A. García leg., 5.I_ 18-23.IX.2012, 3 ♂ (ICN-Ar-8020), 2 ♀ (ICN-Ar-8021).
Diagnosis. Males of Tenedos andes Jocqué & Baert, 2002, resemble those of T. medina sp. n. and T. carlosprietoi sp. n., by the presence of basal retrolateral tibial apophysis (bRTA); rounded concave median apophysis (MA) (see Jocqué & Baert, 2002: 83, fig. 7A–B; figs 94A–D; 95A–B; 97A–D, 98A–B; 99A–F; 101A–D; 102A–B; 104A–D), but can be distinguished by median apophysis with slight notch at external edge, long, wide; apically rounded retrolateral tibial apophysis (RTA); short and quadrangular basal retrolateral tibial apophysis close to retrolateral tibial apophysis (Figs 94A–D; 95A–B). Females are similar to those of Tenedos medina sp. n. and T. carlosprietoi sp. n., by curved lateral borders, forming large atrium (A) (Figs 94E–F; 95C–D; 97E–F, 98C–D; 101E–F; 102C–D; 104E–F), but can be recognized by very large median field plate (MFP), occupying almost 50% of dorsal region of epigyne, short lateral borders (LB) thin at basal side; long and thin seminal receptacles (SR) (Figs 94E–F; 95C–D).
Redescription. Male (Holotype, AMNH_IZC 00217585). Coloration (Fig. 93A–B): carapace brown-reddish. Chelicerae with paturon brown, fangs brown-reddish. Endites light brown, white on anterior region. Labium and sternum light brown. Legs: Coxae I –IV pale beige. Femora I –IV light yellow from base to medial region, brown the rest of their extension. Patella I yellow, II–IV light brown. Tibia I pale yellow with dark spots on the base, II–IV yellow with dark lateral spots. Metatarsus I brown, II–IV yellow with dark spots on the base. Tarsi I –IV yellow. Abdomen: dorsally dark gray with ten white guanine spots organized as follows: two irregular spots very close to each other partially fused in medial region, anteriorly positioned; two longitudinal spots larger than previous ones, anteromedially positioned; four irregular spots, forming a cross, medially positioned; two large and irregular spots, posteriorly positioned. Laterally dark gray with a wide and oblique longitudinal stripe, extending to posterior side. Ventrally light gray with two large anterior spots and several small light spots uniformly distributed on abdomen. Spinnerets light yellow.

Palp: retrolateral process of cymbium (RPC) long, wide with small rounded projection on anterior side; tegulum (T) large, rounded, almost as long as wide; subtegulum (St) large, longer than wide; conductor (C) developed, wide with granulate cuticle; appendix (ApC) short, apically sharp; embolus (E) long, filiform towards apex; base of embolus (EB) approximately as long as three times as basal tegular membrane width; basal tegular membrane (BTM) originated proximally on tegulum, proximally flattened, ending as short, sharp appendix; spermatic ducts (SD) S-shaped, both folds full open, thin; ventral tibial apophysis (VTA) small, triangular-shaped in ventral view; median apophysis (MA) large, rounded, slight notch on external edge; retrolateral tibial apophysis (RTA) large, longer than palpal tibia, shovel-shaped; basal retrolateral tibial apophysis (bRTA) short, square-shaped (Figs 94A–D; 95A–B).
