• Notes:
  • 🧕 Hinger et al. (2020) assigned this genus to the family Rhodobacteraceae Garrity et al. 2006. Publication: Hinger I, Ansorge R, Mussmann M, Romano S. Phylogenomic Analyses of Members of the Widespread Marine Heterotrophic Genus Pseudovibrio Suggest Distinct Evolutionary Trajectories and a Novel Genus, Polycladidibacter gen. nov. Appl Environ Microbiol 2020; 86:0. 🇬🇧
  • 🚂 For the type species of this genus another name is in use, which is affiliated with the genus Pseudovibrio Shieh et al. 2004. Publication: Xu Y, Li Q, Tian R, Lai Q, Zhang Y. Pseudovibrio hongkongensis sp. nov., isolated from a marine flatworm. Antonie Van Leeuwenhoek 2015; 108:127-132. 🇨🇳
  • ❗ Polycladidibacter is the correct name instead if this genus is regarded as a separate genus (i.e., if its nomenclatural type is not assigned to another genus whose name is validly published, legitimate and not rejected and has priority).
  • 🎰 The BRCs most frequently used for deposits in this group are: KCTC: 2; MCCC: 2.
