Strain TB1-E2-13 was isolated from water collected from the Tidal Basin in Washington, D.C., USA, due to the bright purple colour of its colonies, and was taxonomically evaluated with a polyphasic approach. 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).
菌株TB1-E2-13是从美国华盛顿特区潮汐盆地采集的水样中分离出来的，因其菌落呈亮紫色，并用多相方法进行了分类学评估。对部分16S rRNA基因序列的比较发现，菌株TB1-E2-13与该属中的物种最为相似。为了进行更精确的分类学推断，进行了系统基因组分析，结果表明菌株TB1-E2-13与 、 、 和 关系最为密切。基因组指数分析发现，菌株TB1-E2-13与该属其他成员之间的成对比较结果低于物种新颖性阈值。基于多相特征以及基因组和分类学数据差异的识别，菌株TB1-E2-13代表一个新物种，为此提出名称 新种。模式菌株为TB1-E2-13（=ATCC TSD-339=JCM 36076）。
