• Notes:
  • 🚂 For the type species of this genus another name is in use, which is affiliated with the genus Sphaerochaeta Ritalahti et al. 2012. Publication: Abt B, Han C, Scheuner C, Lu M, Lapidus A, Nolan M, Lucas S, Hammon N, Deshpande S, Cheng JF, et al. Complete genome sequence of the termite hindgut bacterium Spirochaeta coccoides type strain (SPN1^T), reclassification in the genus Sphaerochaeta as Sphaerochaeta coccoides comb. nov. and emendations of the family Spirochaetaceae and the genus Sphaerochaeta. Stand Genomic Sci 2012; 6:194-209.
  • ❗ Parasphaerochaeta 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 phylogenomic assignment score of this taxon is 0.10546 (N = 2).
  • 🎰 The BRCs most frequently used for deposits in this group are: DSM: 1; ATCC: 1.
  • 🧍 Even in the phylogenetic analysis conducted by Bidzhieva et al. (2020) Sphaerochaeta sensu lato was revealed as monophyletic. Hördt et al. (2020) found no reason to dissect Sphaerochaeta. Publication: Hordt A, Lopez MG, Meier-Kolthoff JP, Schleuning M, Weinhold LM, Tindall BJ, Gronow S, Kyrpides NC, Woyke T, Goker M.
