Abstract

was proposed as a novel member of genus in 2016. Some time earlier, has been proposed as a novel species of a novel genus named . When comparing the 16S rRNA gene sequences of type strains NH6-79 and D11M-2, they showed 97.9 % sequence identity, much higher than the sequence identities 92.7–94.3 % between NH6-79 and type strains in the genus , indicating that the later proposed novel taxon need reclassification. The phylogenetic trees based on 16S rRNA gene sequences and genome sequences both showed that NH6-79 and D11M-2 formed a separated branch away from strains in the genera , and . The average amino acid identity and average nucleotide identity values of NH6-79 and D11M-2 were 87.9 and 85.0 %, respectively, much higher than the values between NH6-79 and other closely related type strains (54.3 %–58.1 % and 68.6–70.4 %, respectively). NH6-79 and D11M-2 also contained summed feature 8 (C 6 and/or C 7c) and C as major fatty acids, distinguishing them from other closely related taxa. Based on the results of the phylogenetic, comparative genomic and phenotypic analyses, should be reclassified as nom. nov. and the description of genus is emended.
