Etymology. The specific name is a noun in apposition taken from the type locality
Diagnosis. Males of Tenedos macagual sp. n. resemble those of T. hoeferi Jocqué & Baert, 2002 and T. ticuna sp. n., by having a developed conductor (C), curving at prolateral region, where it is very thin (see Jocqué & Baert, 2002: 100, fig. 18A–E; figs 22A–D; 23A–B; 32A–D; 33A–B), but can be recognized by their bifid retrolateral tibial apophysis (RTA) with short and thin anterior branch (aRTA), and long, concave and straight posterior branch (pRTA); long and laminar median apophysis (MA), ending as three short tips (Figs 32A–D; 33A–B). Females are characterized by having very long seminal receptacles (SR), bending over on themselves, large spermathecae (S), small median field plate (MFP), and short and posteriorly situated lateral borders (LB), delimiting a quadrangular atrium (A) (Figs 32E–F; 33C–D).
Description. Male (Holotype, LEUA-00000035887). Coloration (Fig. 31A–B): carapace orange, dark brown in borders, marginal bands posteriorly widened. Chelicerae with paturon brown, brown-reddish fangs. Endites light brown, white on distal region. Labium and sternum light brown. Legs: Coxae I–IV white. Femora I–IV dark yellow, darker on distal side. Patellae I–IV light brown. Tibia I light brown on base, distally light brown, II–IV light brown with dorsal yellow spots. Metatarsi-tarsi, I–IV light brown. Abdomen: dorsally dark gray with seven white guanine spots organized as follows: two rounded and small spots, anteriorly positioned; two sub-oval spots larger than previous ones, sub-medially positioned; two large and sub-triangular spots, medially positioned; a transversal and irregular spot, posteriorly positioned. Laterally dark gray with a wide oblique stripe. Ventrally dark gray with a large white spot that covered 2/3 of the abdomen. Spinnerets brown. Measurements: total length 4.61, carapace length 2.42, width 1.54, height 0.92. Clypeus height 0.42.
