Figs 25 ; 26C–D ; 106 .

Type material. Holotype: COLOMBIA. Nariño: Territorio Cofán, Leaf litter, Winkler extractor, 1000m, E. González leg., 1 ♂ (ICN-Ar-8022).

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

Diagnosis. Males of Tenedos narinensis sp. n., can be recognized from remain species of barronus group by flattened, laminar, large median apophysis (MA) with short posterior extension; bifid retrolateral tibial apophysis (RTA), posterior branch (pRTA) long, curved, anterior branch (aRTA) laminar-shaped ( Figs 25C–F ; 26C–D ).

Description. Male (Holotype, ICN-Ar-8022). Coloration ( Fig. 25A–B ): carapace brown, dark brown in margins; brown thoracic grooves, faint. Chelicerae with paturon brown and brown-reddish fangs. Endites light yellow. Labium and sternum light brown. Legs: Coxae I–IV light brown. Femora I–IV brown on base, yellow the rest of their extension. Patellae, metatarsi I–IV yellow. Abdomen: dorsally gray, spots pattern undistinguished, due poorly preservation of the specimen. Lateral and ventrally, dark gray. Spinnerets light yellow. Measurements: total length 5.13, carapace length 2.61, width 1.62, height 1.59. Clypeus height 0.47. Eye diameters and interdistances: AME 0.09, ALE 0.10, PME 0.11, PLE 0.11; AME–AME 0.11, AME–ALE 0.22, AME–PME 0.16, PME–PME 0.26, PME–PLE 0.32, ALE–PLE 0.25. Chelicerae 0.72 length. Sternum length 1.03, width 0.96. Legs: I—femur 2.18/ patella 0.73/ tibia 1.78/ metatarsus 1.49/ tarsus 1.14/ total 7.32; II—1.85/ 0.62/ 1.47/ 1.40/ 0.90/ 6.21; III—1.71/ 0.62/ 1.24/ 1.65/ 0.92/ 6.14; IV—2.02/ 0.84/ 1.65/ 2.49/ 1.18/ 8.18. Abdomen length 2.31. Legs spines pattern (only the differences from the general pattern): I—tibia v2-2-2, p0-1-1, metatarsus v2-2-2. Palp: retrolateral process of cymbium (RPC), long, wide; tegulum (T) large, rounded, longer than wide, retrolateral excavation few accentuated; subtegulum (St) large, longer than wide, globose, covered by embolus and conductor in ventral view; conductor developed, wide, with short, thin sclerotized region on distal side; appendix (ApC) short, apically sharp; embolus (E) long, filiform towards apex; base of embolus (EB) approximately as long as basal tegular membrane; basal tegular membrane (BTM) originated basally on tegulum, proximally flattened, reticulated, ending as short, sharp appendix; spermatic ducts (SD) S-shaped, anterior fold full open; ventral tibial apophysis (VTA) short, quadrangular-shaped in ventral view; median apophysis (MA) large, flattened, irregular in borders; retrolateral tibial apophysis (RTA) large, almost as long as palpal tibia ( Figs 25C–F ; 26C–D ).

Female. Unknown.

Distribution. Known from Nariño department ( Fig. 106 ).
