Abstract

A strain of the recently validated species shares 99.0 % 16S rRNA gene sequence similarity with the type strain of . The aim of this study was to evaluate the taxonomic relationship between and JCM 31915 showed 73.0 % digital DNA–DNA hybridization (dDDH) value with JCM 39347. The average nucleotide identity (ANI) value between these two strains was 96.7 %. These results indicate that JCM 31915 and JCM 39347 represent members of the same species. Based on these data, we propose as a later heterotypic synonym of . An emended description is provided.
