We request an Opinion of the Judicial Commission regarding rejection of the species Methanothrix soehngenii VPHuser, Wuhrmann and Zehnder 1983, 439, and the genus Methanothrix VPHuser, Wuhrmann and Zehnder 1983, 439, as nomina confusa because their descriptions were based on the characterization of an impure type strain, strain OpfikonT. We also propose the transfer of Methanothrix thermophila VPKamagata et al. 1992, 465, to the genus Methanosaeta as Methanosaeta thermophila comb. nov.
