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 13d, 23c), and a rounded basal widening of the embolus (bwe) (Figs 13c–d, 23a–b). 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–f, 25d, 25j).

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–d, 23a–c).
