Etymology. The specific epithet is a patronymic dedicated in honor of Jimmy Cabra’s son, Gabriel Cabra “Gabi”.

Diagnosis. Males of Tenedos gabi sp. n. resembles those of T. anchicaya sp. n. by having median apophysis apically very thin, with squared base ( Figs 27A–D ; 28A–B ), but can be distinguished by conductor apically rounded not curved at prolateral side, longer and apically curved anterior branch of retrolateral tibial apophysis (aRTA); long, wide in the base with medial furrow posterior branch (pRTA), and by the large tegular apophysis with rounded tip ( Figs 30 , 32A–D ; 31A–B ). Females are similar to those of T. anchicaya sp. n. by the long copulatory ducts (SD), but can be distinguished by the shape of atrium, which is vessel-shaped, and wider copulatory ducts (SD), describing approximately six turns on spermathecae ( Figs 30E–F ; 31C–D ).

Female (Paratype, MUSENUV 2430). Coloration and abdominal pattern of spots as male, but more pigmented: carapace uniformly brown, legs light brown, abdominal spots more rounded ( Fig. 29C–D ). Measurements: total length 4.11, carapace length 1.81, width 1.17, height 0.72. Clypeus height 0.40.

Legs: I—femur 1.12/ patella 0.47/ tibia 0.99/ metatarsus 0.86/ tarsus 0.74/ total 4.18; II—0.96/ 0.44/ 0.81/ 0.73/ 0.61/ 3.55; III—0.91/ 0.38/ 0.73/ 0.77/ 0.59/ 3.38; IV—1.16/ 0.47/ 1.11/ 1.23/ 0.85/ 4.81. Abdomen length 2.31. Legs spines pattern (only the differences from the general pattern): III—tibia v 1p-1p-2; IV—tibia v 1p-1p-2. Epigyne: lateral borders (LB) short, strongly sclerotized, apically pointed, internally straight, forming posterior, small atrium (A); median field plate (MFP) small, sub-quadrangular-shaped with rounded basal edge; copulatory ducts (CD) long, thin, describing less than six turns, transversely oriented; spermathecae (S) small, sub-rounded, posteriorly positioned; fertilization ducts (FD) almost as long as spermathecae ( Figs 30E–F ; 31C–D ).

Variation. Males (n=4): total length: 3.71–3.88; carapace length: 1.80–1.94; femur I length: 1.20–1.27. Females (n=5): total length: 3.98–4.01; carapace length: 1.65–1.81; femur I length: 1.12–1.21. Some males can have brown-reddish carapace bordered in dark brown, the abdomen usually has more defined and sub-rounded spots.

Distribution. Known from Quindío and Valle del Cauca departments ( Fig. 45 ).
