Comparison of a partial 16S rRNA gene sequence found that strain TB1-E2-13 was most similar to species in the genus. For more precise taxonomic inference, a phylogenomic analysis was conducted and indicated that strain TB1-E2-13 was most closely related to , '', and . Analyses of genomic indices found that pairwise comparisons between strain TB1-E2-13 and other members of the genus returned values below the threshold of species novelty. Based on a polyphasic characterization and identifying differences in genomic and taxonomic data, strain TB1-E2-13 represents a novel species, for which the name sp. nov. is proposed. The type strain is TB1-E2-13 (=ATCC TSD-339=JCM 36076).
