This article is a validation list from the International Journal of Systematic and Evolutionary Microbiology that formally establishes the valid publication of 24 new bacterial names and combinations that were previously published in other journals. The list includes newly proposed genera (Anaerostipes, Haliangium, Inquilinus, and Laribacter) and numerous new species spanning diverse bacterial groups, including anaerobes from human feces, sulfate-reducing bacteria, halophilic myxobacteria, psychrophilic organisms from Antarctica, and thermophilic archaea. Each entry specifies the organism name, proposing authors, and the nomenclatural type strain with culture collection accession numbers. The validation process confirms that all requirements for proper bacteriological nomenclature have been met, with the official publication date being the date of this list rather than the original publication date. The authors note that validation is procedurally distinct from taxonomic acceptance, and names may later be reclassified or recognized as synonyms as scientific knowledge advances.

Key findings

• 24 new bacterial names and combinations were formally validated through this publication list
• Four new genera were established: Anaerostipes, Haliangium, Inquilinus, and Laribacter
• Organisms include diverse environmental and clinical isolates: human fecal bacteria, halophilic myxobacteria, psychrophilic Antarctic bacteria, and thermophilic archaea
• Validation date is the publication date of this list, not the original publication date of the names
• Nomenclatural validation does not constitute taxonomic acceptance and names remain subject to future revision
