Etymology. The epithet is a noun in apposition that honors the Cacique Tundama  , leader and lord of the indigenous people that inhabited the Duitama region of the Boyacá department, one of the four supreme rulers of the Muisca Confederation, in the 16th century. Renowned for his brave and fierce defense of the Muisca territories against the Spanish invaders.

Diagnosis. Males of A. tundama  sp. nov. are similar to those of A. zipa  sp. nov by the shape of the RTA, the presence of basal widening of the embolus (bwe), and the absence of a dorsal tibial spur (DTS) in the palp. However, they can be distinguished from those by the straight shorter embolus, the absence of a process on the embolic disc (PED), the presence of a proventral and proximal femoral bump (PvFB, black arrow in Figs 13dView FIGURES 13, 23cView FIGURES 23), and a rounded basal widening of the embolus (bwe) ( Figs 13c –dView FIGURES 13, 23a –bView FIGURES 23). Females of A. tundama  sp. nov. are similar to those of A. zipa  sp. nov. by the general disposition of the internal structures of the epigyne, but they can be recognized from those for their shorter copulatory ducts, smaller sparmathecae, and the presence of a bilobed medial and posterior pocket in the epigyne ( Figs 13e –fView FIGURES 13, 25d, 25jView FIGURES 25).

Description. Male (holotype). Total length: 2.98. Carapace yellow with two black posterior longitudinal stripes, 1.43 long, 0.97 wide, 0.72 high ( Fig. 18gView FIGURES 18). OC black, 0.57 long. Anterior eye row 0.93 wide and posterior 0.91 wide. Sternum yellow, 0.63 long, 0.45 wide. Labium yellow, 0.12 long, 0.21 wide. Chelicerae yellow with three retromarginal and two promarginal teeth. Palp yellow with cymbium brown, with slender and longer RTA, a proventral and proximal femoral bump (PvFB), presence of basal widening of the embolus, and a straight TL and embolus ( Figs 13c –dView FIGURES 13, 23a –cView FIGURES 23). Legs 4312, all yellow. Leg macrosetae: patella, III r 1 me; tibia, I v 2-2 -2; II v 1-1; III v 1-1, p 1-1, r 1 di; IV v 1 pr, p 1-1, r 1-1; metatarsus, I v 2-2; II v 2-2, p 1 di; III –IV v 1-1, p 1-2, r 1-2. Abdomen light brown with two longitudinal dark brown stripes, with a posterior crosslinked pattern of stripes ( Fig. 18gView FIGURES 18).

Variation (n= 4 males). Total length 2.98–3.36. Carapace length 1.43–1.78.

Female (paratype, ICN –Ar 7845). Total length 3.37. Carapace yellow with two posterior dark brown longitudinal stripes, 1.40 long, 1.00 wide, 0.67 high ( Fig. 18hView FIGURES 18). OC black, 0.57 long. Anterior eye row 0.96 wide and posterior 0.87 wide. Sternum yellow, 0.71 long, 0.46 wide. Labium yellow, 0.12 long, 0.19 wide. Chelicerae yellow, with three retromarginal and two promarginal teeth. Legs 4312, all yellow. Leg macrosetae: femur, II –III d 1 di; tibiae, I v 2-2 -2; II v 1-2 -2, p 1 di; III –IV v 1 pr, p 1-1, r 1-1; metatarsus, I v 2-2; II v 2-2, p 1 di; III v 2-1, p 1- 2, r 1-2; IV v 1-1, p 1-1-2, r 1-2. Abdomen light brown, with a dark brown longitudinal stripe, that is reticulated in its posterior middle ( Fig. 18hView FIGURES 18). Epigyne ( Figs 13e –fView FIGURES 13, 25d, 25jView FIGURES 25) with anterior copulatory openings, a posterior bilobed medial pocket, and anterior rounded spermathecae.

Variation (n=10 females). Total length 3.02–3.98. Carapace length 1.40–2.50. Some females are darker, with their carapace dark brown with a posterior longitudinal white stripe, and abdomen black with some small medial white marks (ICN –Ar 7846, Fig. 18iView FIGURES 18).

Comments. All material examined was collected in a preserved high-mountain Páramo ecosystem ( Fig. 26aView FIGURES 26), in Frailejón rotten trunks ( Espeletia  sp.), and in a smaller number beating low shrubs.

Distribution. Colombia (Boyacá) ( Fig. 27View FIGURE 27). Known altitudinal distribution: 3600–3800 m.
