Solving the remaining problems with names of classes. Request for an Opinion.

Area of Science:

• Microbiology
• Taxonomy
• Nomenclature

Background:

• The International Code of Nomenclature of Prokaryotes (ICNP) governs the naming of prokaryotes.
• A recent decision made Rule 8 of the ICNP non-retroactive, impacting the legitimacy of prokaryotic class names.
• This change introduced new nomenclatural uncertainties despite resolving some prior issues.

Approach:

• Reviewing the legitimacy, spelling, and gender of prokaryotic class names published under the ICNP.
• Analyzing the impact of the non-retroactivity of Rule 8 on existing class names.
• Proposing specific actions to the Judicial Commission for clarification and correction.

Key Points:

• Some previously legitimate class names became illegitimate, while others remained illegitimate.
• Ten class names are proposed for rejection: Anoxyphotobacteria, Archaeobacteria, Bacteria, Firmibacteria, Microtatobiotes, Oxyphotobacteria, Photobacteria, Proteobacteria, Schizomycetes, and Scotobacteria.
• Five class names require orthographic correction: Aquificae, Chrysiogenetes, Gemmatimonadetes, Opitutae, and Verrucomicrobiae.

Conclusions:

• The Judicial Commission is requested to provide official clarifications on the status of these prokaryotic class names.
• Implementing the proposed rejections and corrections will enhance taxonomic stability and clarity within prokaryotic nomenclature.
• Resolving these nomenclatural issues is crucial for accurate scientific communication and future research in prokaryotic diversity.
