Figs 15a–d, 19c–d, 23f–g, 25f, 25l, 27

Types. Holotype: male from Camino Real, Parque Nacional Natural Tamá, Santander, Colombia, 2500 m [7.297492°N, 72.263947°W], VI.1999, E. González (ICN –Ar 3363). Paratype: one female from Sendero Binacional, Parque Nacional Natural Tamá, Santander, Colombia, 2470 m [7.297492°N, 72.263947°W], unknown coll. (ICN –Ar 3364).

Etymology. The epithet is a noun in apposition that honors one of the four supreme rulers of the Muisca Confederation, ancient inhabitants of the central Andean highlands of the present-day Colombia’s Eastern Range: the Zipa, the Zaque, the Iraca and the Tundama.

Diagnosis. Males of A. zipa sp. nov. are similar to those of A. tundama 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 curved and longer embolus, the presence of a bilobed process on the embolic disc (PED), the presence of a proventral and proximal femoral widening (PvFw, black arrow in Figs 15a, 23g), and a pointed basal widening of the embolus (bwe) (Figs 15a–b, 23f–g). Females of A. zipa sp. nov. are similar to those of A. tundama sp. nov. by the general disposition of the internal structures of the epigyne, but can be recognized for the their longer copulatory ducts, larger spermathecae, and the absence of the bilobed medial and posterior pocket in the epigyne (Figs 15c–d, 25f, 25l).
