In bombardments of ${}^{238}$U targets with 186-MeV ${}^{34}$S projectiles we discovered the $\alpha$-decaying nuclide ${}^{267}$108 with a half-life of ${19}_{-10\mathrm{}}^{+29\mathrm{}}$ ms, $E_{\alpha }=9.74\mathrm{}$ to 9.87 MeV, and a production cross section of about 2.5 pb. The new nuclide was identified by measuring correlations in energy, time, and position to establish genetic links between its implantation in a position-sensitive silicon detector and subsequent $\alpha$ decay followed by $\alpha$ decays of known descendant nuclides.
