• Notes:
  • 🧒 Göker (2022) assigned the genus Sinorhodobacter Yang et al. 2018 to this family. Publication: Goker M. Filling the gaps: missing taxon names at the ranks of class, order and family. Int J Syst Evol Microbiol 2022; 72:5638.
  • 🧒 Göker (2022) assigned the genus Anianabacter Azpiazu-Muniozguren et al. 2023 to this family. Publication: Goker M. Filling the gaps: missing taxon names at the ranks of class, order and family. Int J Syst Evol Microbiol 2022; 72:5638.
  • 🚃 The type genus of this family has alternatively been placed in the family Rhodobacteraceae Garrity et al. 2006. Publication: Garrity GM, Bell JA, Lilburn T. Family I. Rhodobacteraceae fam. nov. In: Brenner DJ, Krieg NR, Staley JT, Garrity GM (eds), Bergey's Manual of Systematic Bacteriology, 2nd edn, vol. 2 (The Proteobacteria), part C (The Alpha-, Beta-, Delta-, and Epsilonproteobacteria), Springer, New York, 2005, p. 161.
  • 🙄 This taxon name is occasionally misprinted (or affected by an OCR error) in some sources as: "Paracococaceae".
  • 💁 Taxonomists who have recently focused on this group are the corresponding authors of Szuroczki et al. (2022), Tarhriz et al. (2019), Wang et al. (2021), Bryantseva et al. (2015), He et al. (2025). Editors in search of reviewers are advised to consider additional criteria such as whether a taxon is covered by one of the ICSP subcommittees.
  • ✏ The authority of the taxon name (Liang et al.) deliberately differs from the author of the publication (Göker).
  • 🎰 The BRCs most frequently used for deposits in this group are: KCTC: 175; JCM: 109; DSM: 108; LMG: 82; MCCC: 68; CGMCC: 67; NBRC: 62; CIP: 41; ATCC: 41; CCTCC: 37.
  • 🧍 Göker (2022) explicitly assigned only the genera Albidovulum, Allgaiera, Cereibacter, Cypionkella, Defluviimonas, Frigidibacter, Fuscovulum, Gemmobacter, Haematobacter, Luteovulum, Methylarcula, Paenirhodobacter, Paracoccus, Pararhodobacter, Phaeovulum, Pseudorhodobacter, Rhodobaca, Rhodobacter, Roseibaca, Roseicitreum, Roseinatronobacter, Sinirhodobacter, Tabrizicola, Thioclava and Wagnerdoeblera to the family Paracoccaceae. However, since Paracoccaceae is a replacement name for the name Rhodobacteraceae (which contravenes the ICNP), and since the study by Liang et al. (2021) did not consider all genera of Rhodobacteraceae, additional genera may taxonomically be assigned to Paracoccaceae although they would phylogenetically be placed in Roseobacteraceae.
