In this work we will extend the inert-doublet model (IDM) by adding a new gauge symmetry to it, under which, a even scalar () and odd right handed component of two exotic charged leptons , are charged. We also add one even real scalar () and one complex scalar (), three neutral Majorana right handed fermions (), two left handed components of the exotic charged leptons as well as are all odd under the , all of which are not charged under the . With these new particles added to the IDM, we have a model which can give two scalar DM candidates, together they can explain the present DM relic density as well as the muon (g-2) anomaly simultaneously. Also in this model the neutrino masses are generated at one loop level. One of the most peculiar feature of this model is that non-trivial solution to the axial gauge anomaly free conditions lead to the prediction of a stable very heavy partner to the electron (), whose present collider limit (13 TeV LHC) on its mass should be around few TeV.
