Performing in this paper the duality and statefinder diagnostic for a class of Quintom models of Dark Energy which is constructed by the spinor field, we study the possible connections among different Spinor Quintom models and differentiate the Quintom dark energy in spinor scenario from the others. A class of evolutionary trajectories of these Quintom models in Spinor field are plotted in the statefinder parameter planes. We also find that the power-law-like potential also plays important role in this class of models from the statefinder viewpoint.
