Gutiérrez leg., 04.XII.2016 , 1 ♂ (ICN-Ar-12342). Etymology. The epithet is a noun in apposition honoring to Wayuu, indigenous people who live in the Guajira department. Diagnosis. Males of Tenedos wayuu sp. n. , can be distinguished from remaining species of barronus group by square-shaped median apophysis (MA) with very short appendix at posterior side; short, wide retrolateral tibial apophysis (RTA) ( Figs 24C–F ; 26A–B ). Description. Male ( Holotype , ICN-Ar-12342). Coloration ( Fig. 24A–B ): carapace dark brown with anterior black spots. Chelicerae with paturon brown, brown-reddish fangs. Endites light yellow, white on anterior region. Labium and sternum brown. Legs: Coxae I–IV light yellow. Femora I–IV yellow from base to median region, proximally brown. Patellae I–IV light brown on base, yellow the rest of their extension. Tibiae I–IV yellow, brown from medial to distal region. Metatarsus I brown, II–IV yellow. Tarsi I–IV yellow. Abdomen: dorsally dark gray with sixteen white guanine spots organized as follows: one irregular and large spots, anteriorly positioned; two lateral spots larger than previous one, anteromedially positioned; two small and rounded spots, medially positioned; posterior to the mentioned spots, two symmetrical groups of spots can be identified, which decrease in size towards posterior side of the abdomen: a first group conformed by six rounded and lateral spots, three on each side, and a second group of five long and transversal spots. Laterally light gray with three long and oblique stripes, decreasing in size towards posterior side. Ventrally dark gray with several spots uniformly distributed. Spinnerets light brown. Measurements: total length 4.85, carapace length 2.79, width 1.94, height 1.11. Clypeus height 0.49. Eye diameters and interdistances: AME 0.07, ALE 0.11, PME 0.09, PLE 0.10; AME–AME 0.17, AME–ALE 0.24, AME–PME 0.35, PME–PME 0.25, PME–PLE 0.41, ALE–PLE 0.33. Chelicerae 1.01 length. Sternum length 1.14, width 1.05. Legs: I—femur 1.74/ patella 0.75/ tibia 1.65/ metatarsus 1.40/ tarsus 1.01/ total 6.55; II—1.80/ 0.69/ 1.66/ 1.54/ 1.03/ 6.72; III—1.52/ 0.77/ 0.96/ 1.54/ 0.80/ 5.59; IV—1.95/ 0.85/ 1.66/ 2.18/ 1.02/ 7.64. Abdomen length 2.06. Legs spines pattern (only the differences from the general pattern): III—femur d0-0-1p, p0; IV—femur p0, r0. Palp: retrolateral process of cymbium (RPC) long and wide, widening towards base; tegulum (T) large, rounded, almost as long as wide, retrolateral excavation few accentuated; subtegulum (St) longer than wide; conductor (C) developed, wide, with short sclerotized region on distal side; appendix (ApC) long, sharp; embolus (E) long, filiform towards apex; base of embolus (EB) approximately three times as long as basal tegular membrane; basal tegular membrane (BTM) originated basally on tegulum, ending as very short appendix; spermatic ducts S-shaped (SD), anterior fold wider than posterior; ventral tibial apophysis (VTA) very small, quadrangular; median apophysis (MA) large, bifid, anterior branch (aMA) square-shaped, folded in edges; retrolateral tibial apophysis (RTA) almost as long as palpal tibia, very wide at base, conical-shaped ( Figs 24C–F ; 26A–B ).
