abstract: The Judicial Commission affirms that the genus name Methanothrix Huser et al. 1983 and the species combination Methanothrix soehngenii Huser et al. 1983 do not contravene Rule 31a and are not to be considered as rejected names. The genus name Methanosaeta Patel and Sprott 1990 applies to the same taxon as Methanothrix Huser et al. 1983 and is therefore a later heterotypic synonym. The combinations Methanothrix thermoacetophila corrig. Nozhevnikova and Chudina 1988 and Methanothrix thermophila Kamagata et al. 1992 are considered to refer to the same taxon, a consequence of which is that Methanothrix thermophila Kamagata et al. 1992 contravenes Rule 51b and is placed on the List of Rejected Names.
