  Dual spherical conchoidal motion has been defined by Yapar. In this work, we
define this motion on a dual hyperbolic unit sphere in the dual Lorentzian
space with dual signature, and the results carried to the Lorentzian lines
space by means of the Study s mapping. We also obtain the study maps of the
orbits drawn on the fixed dual hyperbolic unit sphere by unit dual vectors of
an orthonormal base .
