Diagnosis. Males of Tenedos carlosprietoi sp. n., resemble those of T. andes Jocqué & Baert, 2002 and T. medina sp. n., by presence of basal retrolateral tibial apophysis (bRTA), rounded median apophysis (MA) (see Jocqué & Baert, 2002: 83, fig. 7A–B; figs 94A–D; 95A–B; 97A–D, 98A–B; 99A–F; 101A–D; 102A–B; 104A–D), but can be distinguished by larger median apophysis, apically bifid basal retrolateral tibial apophysis; wider retrolateral tibial apophysis (RTA) ( Figs 101A–D ; 102A–B ; 104A–D ). Females are similar to those of Tenedos andes Jocqué & Baert, 2002 and T. medina sp. n., by the large median field plate (MFP) ( Figs 94E–F ; 95C–D ; 97E–F , 98C–D ; 101E–F ; 102C–D ; 104E–F ), but can be recognized by longer than wide, cylindrical-shaped atrium (A), very wider seminal receptacles (SR), ending at anterior region of median septum of epigyne, wider and longer lateral borders (LB) ( Figs 101E–F ; 102C–D ; 104E–F ).

Description. Male (Holotype, IAvH-I-605). Coloration ( Fig. 100A–B ): carapace with light brown cephalic region, dark-brown in margins. Chelicerae with paturon brown, fangs brown-reddish.

Epigyne: lateral borders (LB) short, very wide, curved towards posterior region of epigyne, forming posterior oval atrium (A); median field plate (MFP) large, quadrangular-shaped; copulatory ducts (CD) very short, wide, almost undistinguished from spermathecae; seminal receptacles (SR) long, very wide, curved towards anteriomedian septum; spermathecae (S) large, irregulars, posteriorly positioned; fertilization ducts (FD) almost as long as spermathecae length ( Figs 101E–F ; 102C–D ; 104E–F ).

Variation. Males (n=3): total length: 6.57–7.32; carapace length: 3.33–3.53; femur I length: 1.09–1.92. Females (n=3): total length: 5.53–6.48; carapace length: 3.27–3.48; femur I length: 0.99–1.97. Population of Tenedos carlosprietoi sp. n. distributed in Cundinamarca department exhibits the following variations in both sexual and somatic features: the prosome present lighter color tonalities, the anterior abdominal scutum is wider and longer ( Fig. 103A–D ), and the variation of spines patterns is I—tibia v1r-1r-1p; II—tibia v1r-1r-1r; IV—tibia v2-2-2. Retrolateral tibial apophysis longer, apically sharp, very short and lightly apically bifid retrolateral tibial apophysis ( Fig. 104A–D ). Females are presenting a shorter atrium and lateral borders and longer seminal receptacles ( Fig. 104E–F ).

Distribution. Known from Cundinamarca and Meta departments, Colombia ( Fig. 106 ).
