In this paper, we introduce the equiform-Bishop frame of a spacelike curve r lying fully on S 2 1 in Minkowski 3-space R 3 1. By using this frame, we investigate the equiform-Bishop Frenet invariants of special spacelike equiform-Bishop Smarandache curves of a spacelike base curve in R 3 1. Furthermore, we study the geometric properties of these curves when the spacelike base curve r is specially contained in a plane. Finally, we give a computational example to illustrate these curves.
