Taxonomic note on and : taxogenomic insights for addressing misidentifications and proposing new combinations and new subspecies No Access

Abstract

Misidentifications of and species often occur due to their overlapping traits, including similar cell shapes, biochemical characteristics and environmental preferences. These revisions aim to address significant overlaps and correct previous misidentifications. Phylogenetic analysis using 16S rRNA gene and core protein sequences has positioned 257T and 36T within the genus . This reclassification is further substantiated by high 16S rRNA gene sequence similarities and average amino acid identity values, which align these species more closely with than with . As a result, we propose the reclassification of 257T and 36T as comb. nov. and comb. nov., respectively, to accurately reflect their taxonomic status. Additionally, average nucleotide identity and digital DNA–DNA hybridization values indicate that KCTC 9943T and DSM 25126T, as well as DSM 20447T and CMS 76orT, surpass the thresholds for subspecies classification. Therefore, we propose the recognition of four new subspecies: subsp. comb. nov., subsp. comb. nov., subsp. comb. nov. and subsp. comb. nov.
