The 16S rRNA gene of Thermobacterium salinum TK19130 T had the highest sequence similarity to that of Luteirhabdus pelagi A3-108 T (99.7%). Phylogeny of 16S rRNA gene and whole genome sequences indicated that T. salinum TK19130 T and L. pelagi A3-108 T are closely related, and represented an independent clade. Whole genome comparisons showed that T. salinum TK19130 T and L. pelagi A3-108 T shared average amino acid identity of 95.3%, indicating they could be merged into the same genus. The digital DNA-DNA hybridization and average nucleotide identity values between T. salinum TK19130 T and L. pelagi A3-108 T were 52.5 and 93.3%, respectively. These values were below the recommended threshold values of prokaryotic species delineation. Thus, based on the principle of priority, we proposed the transfer of Thermobacterium salinum Chen et al . 2023 to the genus Luteirhabdus Ren et al . 2022 as Luteirhabdus salina comb. nov.
