This article is Validation List No. 65 from the International Journal of Systematic Bacteriology, published in 1998. It announces the valid publication of eight new bacterial names and combinations that were previously published outside the IJSB journal. The validation process ensures these names meet all requirements for formal bacteriological nomenclature acceptance. The list includes four new bacterial species: Aureobacterium resistens, Corynebacterium riegelii, Mycobacterium heidelbergense, and three Roseomonas species (R. cervicalis, R. fauriae, and R. gilardii). Additionally, two new genera are validated: Heliobacillus (containing H. mobilis, a photosynthetic bacterium) and Roseomonas. Each entry provides the proposing authors, strain designations, and culture collection references. The article clarifies that valid publication date is the validation list date, not the original publication date, and that inclusion in the list does not constitute taxonomic acceptance, as organisms may later be reclassified or names designated as synonyms.

Key findings

• Eight new bacterial names and combinations received valid publication through this validation list, including four new species and two new genera
• Notable organisms validated include Heliobacillus mobilis, an anoxyphototroph with bacteriochlorophyll g, and three Roseomonas species associated with human infections
• Aureobacterium resistens exhibits vancomycin resistance with teicoplanin susceptibility; Corynebacterium riegelii was isolated from urinary tract infections
• Valid publication date is established as the validation list publication date, not the original description date
• The validation process confirms nomenclatural requirements are met but does not constitute taxonomic acceptance of the organisms
