Recent data on e{sup +}/e{sup −} and p-bar cosmic rays suggest that dark matter annihilate into the standard model (SM) particles through new leptophilic interaction. In this paper, we consider a standard model extension with the gauged U(1){sub L{sub μ−L{sub τ}}} group, with a new Dirac fermion charged under this U(1) as a dark matter. We study the muon (g−2){sub μ}, thermal relic density of the cold dark matter, and the collider signatures of this model. Z{sup '} productions at the Tevatron or the LHC could be easily order of O(1)−O(10{sup 3}) fb.
