The taxonomy of the genus Lactobacillus was revised in April 2020 to reclassify species that were originally described as Lactobacillus species into 25 genera that comprise phylogenetically related micro-organisms. The species in these 25 genera also share major metabolic traits and generally have a shared ecology. A total of four comb. nov. names, however, were not considered validly published because the valid publication of the corresponding basonyms was published in later issues of the International Journal of Systematic and Evolutionary Microbiology. This communication aims to validly publish the names Apilactobacillus bombintestini, Companilactobacillus suantsaicola , Lactiplantibacillus garii and Levilactobacillus suantsaiihabitans .
