    Notes:
    • Emendation accompanied by the inclusion of 2 genera in the family.
    • As of 2020-04-15 this emendation was not yet included in an IJSEM List of Changes in Taxonomic Opinion.

• Notes:
  • Proenca et al. (2018) assigned the genus "Alysiosphaera" to this family. Publication: Proenca DN, Whitman WB, Varghese N, Shapiro N, Woyke T, Kyrpides NC, Morais PV. Arboriscoccus pini gen. nov., sp. nov., an endophyte from a pine tree of the class Alphaproteobacteria, emended description of Geminicoccus roseus, and proposal of Geminicoccaceae fam. nov.

  • The terminology used by the authors is in line with many other taxonomic studies and does not negatively affect their main results; some improvements may nevertheless be possible. Contrasting the term "chemotaxonomic" with "phenotypic" is not recommended. Using the term "phylogenetic data" (or equivalent) for sequence data is not advocated. See the LPSN phylogeny page for details. Publication: Göker M. What can genome analysis offer for bacteria?
