Type material. Holotype: ♂ from Parque Nacional Natural Cueva de Los Guácharos , Vereda La Mesura, Palestina, Huila, Colombia, 1950 m, 1.61565°N, 76.10239°W, 16–21.X.2016, V. Muñoz-Charry (ICN-Ar 8263) . Paratypes: 1♀, the same data as holotype (ICN-Ar 8264) ; 1♂, the same locality data as holotype, IX.2013, M. Fonseca ( ANDES-IN 3232 ) .

Etymology. The epithet comes from the Spanish (“ Colombia en paz” = “ Colombia in peace”), in honor to the recent peace process in the country of the authors, the country that almost all Colombians dream of, and which we hope to construct in the near future. To be treated as an arbitrary combination of letters, and hence without the need to agree in gender with the genus.

Diagnosis. Males of T. colombiaenpaz sp. nov. can be recognized from those of the remaining species in the genus by their larger proventral apophysis of the tibia (PvTa), curved embolus (e), and their smaller median apophysis (ma) ( Figs 44–48 ). Females can be diagnosed by their bigger anterior copulatory opening of the epigynum, and the ventral and posterior insertion of the copulatory ducts in their bigger and rounded spermathecae ( Figs 49–50 ).

Description. Male (holotype). Total length: 4.56. Carapace dark brown, 2.18 long, 1.63 wide, 1.31 high ( Figs 40–41 ). OC dark brown, 0.98 long. Anterior eye row 1.55 wide and posterior 1.42 wide. As in the remaining species in the genus, the PME are unusually enlarged compared to the others. Sternum greenish-black, 1.00 long, 0.79 wide. Labium yellowish-brown, 0.23 long, 0.30 wide. Chelicerae dark brown, with two retromarginal and three promarginal teeth. Palp dark brown, with a curved embolus, small median apophysis (ma), tibia with a larger proventral apophysis (PvTa), and the retrolateral apophysis together with the retroventral apophysis (RvTa) form an extended concavity ( Figs 44–48 ). Leg formula: 4321, all yellow with black marks. Leg macrosetae: I, III p 1 di; II p 1 di, d 1 di; patella, I–III p 1 me; IV p 1 me, r 1 me; tibia, I v 2–2–2, p 1 me; II v 1–2–2, p 1–0–1; III v 1–1–1, p 1–0–1, r 1–0–1, d 1 pr; IV v 1–2–2, p 1–0–1, r 1–0–1, d 1 pr; metatarsus, I v 2–1–2; II v 2–1–1, p 1–0–1; III v 2–0–2, p 1–0–1, r 1–0–1; IV v 2–0–2, p 1–1–0–1, r 1–1–0–1. Abdomen greenish-brown with a disperse pattern of yellow points, four dimpled spots in the medial area and posteromedial chevron marks ( Fig. 40 ).

Female. (paratype, ICN-Ar 8277). Total length 4.95. Carapace dark brown, 2.09 long, 1.64 wide, 1.27 high ( Figs 42–43 ). OC dark brown, 1.01 long. Anterior eye row 1.55 wide and posterior 1.43 wide. Sternum greenishblack, 0.97 long, 0.71 wide. Labium yellowish-brown, 0.31 long, 0.36 wide. Chelicerae dark brown, with two retromarginal and three promarginal teeth. Leg formula: 4321, all brown with dark brown spots. Leg macrosetae: femur, I, III p 1 di; II p 1 di, d 1 di; patella, I–II p 1 me; III–IV p 1 me, r 1 me; tibia, I v 2–2–2, p 1 me; II v 1–1–2, p 1–0–1; III v 1–1–1, p 1–0–1, r 1–0–1; IV v 1–2–1, p 1–0–1, r 1–0–1, d 1 pr; metatarsus, I v 2–1–2; II v 2–0–2, p 1–0–1; III v 1–0–1, p 1–0–2, r 1–0–1, d 1 pr; IV v 2–0–1, p 1–1–0–2, r 1–1–0–2. Abdomen greenish-brown with a dispersed pattern of yellow points and four dimpled spots in the medial area ( Fig. 42 ). Epigynum ( Figs 49–50 ) with a big and posteriorly oval copulatory opening (co), short-wide copulatory ducts, with a ventral and posterior insertion of the copulatory ducts (cd) in the bigger and rounded spermathecae (sp).

Variation. (n= 2 males) Total length 4.56–5.09. Carapace length 2.18–2.57.

Distribution and Comments. Known only from its type locality in the Colombian Andes ( Fig. 57 ). All the material examined was collected in a well-conserved Andean moist forest, by beating in the day moss-covered trunks and the mosses placed in rock-walls.
