  • 🧍 According to the Judicial Commission, the name Methanosaeta is illegitimate and should be rejected as a source of confusion. It should be replaced with the genus name Methanothrix. The replacement name will be nom. nov. (sic) and all species in the genus Methanosaeta should be transferred to the genus Methanothrix. As yet this request is provisional.
