Based on the large relative evolutionary divergence between individual subclades, members of the genus\n                    <jats:italic>Methanobrevibacter<\/jats:italic>\n                    have been reclassified into eight novel genera as new combinations proposed under the rules of the Code of Nomenclature of Prokaryotes Described from Sequence Data. Here, we validly publish the new names for all taxa with type strains also under the rules of the International Code of Nomenclature of Prokaryotes. This includes members of the genera\n                    <jats:italic>Methanacia<\/jats:italic>\n                    ,\n                    <jats:italic>Methanobaculum<\/jats:italic>\n                    ,\n                    <jats:italic>Methanobinarius<\/jats:italic>\n                    ,\n                    <jats:italic>Methanocatella<\/jats:italic>\n                    and\n                    <jats:italic>Methanoflexus<\/jats:italic>\n                    .
