This document is a notification list published in the International Journal of Systematic and Evolutionary Microbiology (IJSEM) volume 58, part 8, announcing newly validated bacterial names and taxonomic changes that appeared in that journal issue. The list serves as a reference tool for the microbiology community to track new species descriptions, new genus designations, emendations to existing genus descriptions, and new taxonomic combinations. The notification includes approximately 50 entries covering diverse bacterial taxa, including species from genera such as Prevotella, Rhodobacter, Blautia, Vibrio, Shewanella, and Pseudomonas, among others. Several entries represent reclassifications where previously named bacteria were moved to newly established genera or had their genus assignments corrected. The list also includes corrections to authorship and typification for various historically important bacterial species. This type of notification serves an essential archival and organizational function in bacterial systematics, helping researchers stay current with valid taxonomic nomenclature according to the International Code of Nomenclature of Prokaryotes.

Key findings

• Approximately 50 new bacterial species names and 8 new bacterial genera were validly published in IJSEM volume 58, part 8 in 2008
• Multiple bacterial species were reclassified into newly established genera, including Blautia (with six species combinations from previously named taxa)
• Several historically recognized bacterial species underwent corrections to authorship attribution and typification designations
• Emendations were made to existing genus descriptions (Thermobifida, Cohnella, Phenylobacterium, and Catellatospora) to accommodate new taxonomic information
