  • 🧍 Later homotypic synonym of Deltaproteobacteria Kuever et al. 2006. Originally, Deltaproteobacteria was illegitimate after Rule 8 was modified regarding the formation of names of classes. In 2022, Deltaproteobacteria became legitimate because the ICSP decided to make Rule 8 non-retroactive. This rendered Myxococcia a later homotypic synonym that contravenes Rule 51b. Publication: Sjöstedt AB. Genus I. Francisella Dorofe'ev 1947, 176AL.
