Etymology. The epithet is a noun in apposition that honors the fourth and last ruler and lord of Bacatá, southern Muisca confederation, and currently known as the Colombian capital Bogotá.

Diagnosis. Males of A. tisquesusa sp. nov. are similar to those of A. pae sp. nov by the shape of the RTA and the absence of the basal widening of the embolus. However, they can be distinguished from those by the longer and pointed RTA, a more rounded tegular lobe (TL), the presence of an evident embolar disc spur (EDS), and a shorter embolus ( Figs 13a–b View FIGURES 13 , 22g –h View FIGURES 22 ).

Legs 4312, all brown with yellowish disperse marks.
