Figs 66–68; 107.
Type material. Holotype: COLOMBIA. Risaralda: Santa Rosa de Cabal, Vereda Campo Alegrito, Parque Municipal Natural Campo Alegre, Finca La Albania, Secondary forest, Pitfall trap, 2490m [4°52′03″N, 75°32′48″W], A. Pulido, Y. Martínez & E. Henao leg., 22-24.II.2004, 1 ♂ (IAvH-I-651). Paratypes: same data as the holotype, 1 ♂ (IAvH-I-654), 1 ♂ (IAvH-I-653), 1 ♀ (IAvH-I-655), 1 ♀ (IAvH-I-656).
Etymology. The specific name is a noun in apposition taken from the type locality.
Diagnosis. Males of Tenedos santarosa sp. n., resemble those of T. eberhardi sp. n. and T. tatama sp. n. by the bifid retrolateral tibial apophysis (RTA) and large median apophysis (MA) (Figs 64A–D; 65A–B; 67A–D; 68A–B; 70A–D; 71A–B), but are distinguished by having thirteen dorsal abdominal spots; wider and laminar posterior branch of the retrolateral tibial apophysis (pRTA); thin, laminar, and long anterior branch (aRTA) with rounded apex; large bifid median apophysis with short, curved anterior branch (aMA), triangular-shaped posterior branch (pMA); large ventral tibial apophysis (VTA) (Figs 67A–D; 68A–B). Females are similar those of Tenedos eberhardi sp. n. and T. tatama sp. n. by lateral borders (LB) reaching the medial region of median field plate (MFP); medial field plate globose in dorsal surface; seminal receptacles forming bowl-shaped in dorsal view (Figs 64E–F; 65C–D; 67E–F; 68C–D; 70E–F; 71C–D).
Description. Male (Holotype, IAvH-I-651). Coloration (Fig. 66A–B): carapace uniformly dark brown. Chelicerae with paturon brown, fangs brown-reddish. Endites brown, white on anterior region. Labium and sternum light brown. Legs: Coxae I–IV light yellow. Femora I–IV with base brown, white on medial region and distally brown. Patellae dark brown. Tibia I pale yellow, II–IV brown with light patches. Metatarsi-tarsi I–IV dark brown. Abdomen: dorsally dark gray with thirteen white guanine spots organized as follows: two elongated spots, anteriorly positioned; two oval spots smaller than previous ones, sub-medially positioned; four transversal and large spots, medially positioned; two sub-rounded spots, in posteromedial position; three transversal spots, liked in medial region, posteriorly positioned. Laterally dark gray without spots. Ventrally dark gray with small spots on lateral sides and a long and wide central spot. Spinnerets light brown.
