Diagnosis. Males of Tenedos quimbaya sp. n. are similar those of Tenedos figaro Jocqué & Baert, 2002 by having a cymbium (Cy) almost as long as tibia + patella length, abundant modified setae on retrolateral side of cymbium, and similar shape of prolateral laminar extension of the conductor (C) ( Fig. 20A–F ), but are distinguished by the shape of median apophysis (MA): with a rounded sub-apical anterior tip, ending as short tubular appendix with apical furrows; posterior branch of the retrolateral tibial apophysis (pRTA) shorter than palpal tibia ( Figs 22A– D ; 23A–B ; 25A–F ). Females are characterized by their wide and transverse copulatory ducts (SD), transversely oriented and quadrangular-shaped atrium (A) ( Figs 22E–F ; 23C–D ).

Legs: Coxae I–III whitish, IV pale yellow. Femora I–IV brown with dark patches on dorsal, retrolateral and prolateral regions, lighter in medial region of ventral edge. Patellae I–IV brown.

Epigyne: lateral borders (LB) short, apically rounded, internally straight, forming posterior, quadrangular-shaped small atrium (A); median field plate (MFP) small and quadrangular-shaped; copulatory ducts long and wide, transversally oriented, describing approximately four tuns on spermathecae; spermathecae (S) large, irregulars, posteriorly positioned; fertilization ducts (FD) almost as spermathecae ( Figs 22E–F ; 23C–D ).

Variation. Males (n=3): total length: 3.59–4.11; carapace length: 1.79–1.82; femur I length: 1.11–1.14. Females (n=12): total length: 3.39–4.03; carapace length: 3.06–3.08; femur I length: 1.71–1.84.

Natural history. Specimens of Tenedos quimbaya sp. n. were collected in sympatry with specimens of Tenedos trilobatus Jocqué & Baert, 2002 on leaf litter at pristine high Andean ecosystems.

Distribution. Known from several localities in Risaralda, Caldas, and Quindío departments, Colombia ( Fig. 46 ).
