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

Diagnosis. Males of Tenedos anchicaya sp. n. are distinguished by extremely developed conductor (C), strongly curved conductor at prolateral side with projected prolateral laminar; short, apically sharp posterior branch of retrolateral tibial apophysis (pRTA); median apophysis (MA) quadrangular in the base, ending as short appendix ( Figs 27A–D ; 28A–B ). Females are characterized by the long copulatory ducts (CD), describing approximately ten turns on spermathecae ( Figs 27E–F ; 28C–D ).

Description. Male (Holotype, IAvH-I-6113). Coloration ( Fig. 26A–B ): carapace reddish, dark brown in margins and cephalic region, with two brown spots in anterior side of fovea. Chelicerae with brown paturon, fangs brown-reddish. Endites light brown, white on anterior region. Labium and sternum brown, dark in borders. Legs: Coxae I– IV yellow. Femora I–IV brown with dark patches on medial regions. Patellae I–IV brown. Tibia I brown from basal to medial side, white the rest of its extension, II–IV brown. Metatarsi-tarsi I–IV brown. Abdomen: dorsally dark gray with six white guanine spots organized as follows: two small, slightly elongated spots, anteriorly positioned; two oblique spots larger than previous ones, with anterior notch, medially positioned; two irregular spots smaller than previous ones medially fused, posteriorly positioned. Laterally dark gray with a white band. Ventrally beige with gray lateral patches. Spinnerets pale brown. Measurements: total length 3.63, carapace length 1.80, width 1.26, height 0.75. Clypeus height 0.40. Eye diameters and interdistances: AME 0.07, ALE 0.05, PME 0.08, PLE 0.09; AME–AME 0.13, AME–ALE 0.14, AME–PME 0.16, PME–PME 0.18, PME–PLE 0.23, ALE–PLE 0.15.

Abdomen length 1.54. Legs spines pattern (only the differences from the general pattern): I—tibia v 2-2-2, metatarsus v 2-2-2; III—femur p 0, tibia v 1p-1p-2. Palp: retrolateral process of cymbium (RCP) narrow, poorly projected; tegulum (T) longer than wide, anteriorly sub-rounded and elongated towards embolus base with prolateral membranous, laminar area at basal region; subtegulum (St) large, wide; conductor (C) strongly curved towards prolateral side, prolateral laminar projection large; appendix (ApC) very short, sharp; embolus (E) emerging basally on tegulum parallel to sagittal edge of cymbium; embolus base (EB) robust, tubular, long; spermatic ducts (SD) visible in retrolateral view, anteriorly very wide; ventral tibial apophysis (VTA) large, robust, sub-rectangular in ventral view; median apophysis (MA) small, slightly recurved; retrolateral tibial apophysis (RTA) with anterior branch (pRTA) almost as long as palpal tibia, anterior branch (aRTA) short, triangular ( Figs 27A–D ; 28A–B ).

Female (Paratype, IAvH-I-6114). Coloration and abdominal pattern of spots as male with some modifications: carapace uniformly brown, legs light brown ( Fig. 26C–D ).

Abdomen length 1.87. Legs spines pattern (only the differences from the general pattern): II—femur p 0-0-1d; III—femur p 0; IV—tibia v 1p-1p-2. Epigyne: lateral borders (LB) very short, apically rounded, forming posterior, rounded atrium (A); median field plate (MFP) small, only internally visible; copulatory ducts (CD) very long, thin, transversely oriented; spermathecae (S) small, sub-rounded, posteriorly positioned; fertilization ducts (FD) almost as long as spermathecae ( Figs 27E–F ; 28C–D ).

Variation. Females (n=4): total length: 3.45–3.80; carapace length: 1.62–1.68; femur I length: 0.63–0.92.
