Etymology. The specific name is a noun in apposition taken from the type locality.

Diagnosis. Males of Tenedos tatama sp. n., resemble those of T. santarosa sp. n., and T. eberhardi sp. n., by shape and bifid retrolateral tibial apophysis (RTA); large median apophysis (MA) ( Figs 64A–D ; 65A–B ; 67A–D ; 68A–B ; 70A–D ; 71A–B ), but are distinguished by thinner posterior branch of the retrolateral tibial apophysis (pRTA) with thin posterior tip; large median apophysis, anteriorly concave ( Figs 70A–D ; 71A–B ). Females are similar those of Tenedos santarosa sp. n., and T. eberhardi sp. n. by can be distinguished by very large, rounded median field plate (MFP); thin seminal receptacles (SR), slightly curved towards median septum ( Figs 64E–F ; 65C–D ; 67E–F ; 68C–D ; 70E–F ; 71C–D ).

Female (Paratype, IAvH-I-666). Coloration and abdominal pattern of spots as male, carapace uniformly brown ( Fig. 69C–D ). Measurements: total length 5.76, carapace length 2.89, width 2.01, height 1.48. Clypeus height 0.53.

Epigyne: lateral borders (LB) short, curved towards posteromedial region of epigyne, forming medial, large atrium (A); median field plate (MFP) very large, rounded; copulatory ducts (CD) very short, wide, almost undistinguished from spermathecae; seminal receptacles (SR) long, rounded at medial region, lightly curved towards median septum; spermathecae (S) large, irregulars, posteriorly positioned; fertilization ducts (FD) almost as long as spermathecae length ( Figs 70E–F ; 71C–D ).

Distribution. Known from Risaralda department ( Fig. 107 ).

Remark. Female and male were matched by having the same abdomen spots patterns and the localities where these specimens are closely related.
