We examine the muonium ([mu][sup +][ital e[minus]])-antimuonium ([mu][sup [minus]][ital e+]) system in the models which accommodate the dilepton gauge bosons, and study their contributions to the ground state hyperfine splitting in muonium.'' We also consider the exotic muon decay [mu][sup +][r arrow][ital e][sup +]+[bar [nu]][sub [ital e]]+[nu][sub [mu]] mediated by the dilepton gauge boson, and obtain a lower bound ([ital M][sub [ital X]][sup [plus minus]]/[ital g][sub 3[ital l]])[gt]550 GeV at a 90% confidence level for the singly-charged dilepton mass using the unitarity relation of the Kobayashi-Maskawa matrix for the three-family case.
