In bombardments of ${}^{238}$U targets with 186-MeV ${}^{34}$S projectiles we discovered the $\ensuremath{\alpha}$-decaying nuclide ${}^{267}$108 with a half-life of ${19}_{\ensuremath{-}10}^{+29}$ ms, ${E}_{\ensuremath{\alpha}}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}9.74$ 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 $\ensuremath{\alpha}$ decay followed by $\ensuremath{\alpha}$ decays of known descendant nuclides.
