Request for an Opinion on the standing and retention of Firmicutes as a phylum name

Abstract

Oren and Garrity recently published 42 new prokaryotic phylum names, including Bacillota , which they describe as a synonym of the effectively published name Firmacutes and its orthographic correction Firmicutes . However, the name Firmacutes was listed as a division in the Approved Lists of Bacterial Names, which suggests that it should be treated as having been validly published. Recent emendations to rules require that a named phylum now requires a named type genus and a phylum name is formed by the addition of the suffix -ota to the stem of the name of the designated type genus. However, there are strong practical arguments for retaining the name Firmicutes , notwithstanding the uncertainty over whether the name already has standing. This matter is referred to the Judicial Commission, asking for an opinion on the standing and retention of the name Firmicutes .
