Following the linear programming prescription of Jafarizadeh et al. [Phys. Rev. A 72, 062106 (2005)], the d(multiply-in-circle sign)d Bell diagonal entanglement witnesses are provided. By using Jamiolkowski isomorphism, it is shown that the corresponding positive maps are the generalized qudit Choi maps. Also by manipulating particular d(multiply-in-circle sign)d Bell diagonal separable states and constructing corresponding bound entangled states, it is shown that the obtained d(multiply-in-circle sign)d Bell states diagonal entanglement witnesses (consequently qudit Choi maps) are nondecomposable in a certain range of their parameters.
