• Notes:
  • 🧒 Catlin (1991) assigned the genus Moraxella Lwoff 1939 (Approved Lists 1980) to this family. Publication: Catlin BW. Branhamaceae fam. nov., a proposed family to accommodate the genera Branhamella and Moraxella. Int. J. Syst. Bacteriol. 1991; 41:320-323.
  • 🛺 The type genus of this family has been placed in the family Moraxellaceae Rossau et al. 1991. Publication: Rossau R, Van Landschoot A, Gillis M, De Ley J. Taxonomy of Moraxellaceae fam. nov., a new bacterial family to accommodate the genera Moraxella, Acinetobacter, and Psychrobacter and related organisms. Int. J. Syst. Bacteriol. 1991; 41:310-319.
  • 🧍 Branhamaceae Catlin 1991 is illegitimate because Moraxella is included and Moraxellaceae has priority. Publication: Rossau R, Van Landschoot A, Gillis M, De Ley J. Taxonomy of Moraxellaceae fam. nov., a new bacterial family to accommodate the genera Moraxella, Acinetobacter, and Psychrobacter and related organisms. Int. J. Syst. Bacteriol. 1991; 41:310-319.
  • 🧍 Irregularly formed name. The expected name to be formed from Branhamella would be "Branhamellaceae". Publication: Oren A, Arahal DR, Christensen H, Goker M, Manaia CM, Moore ERB.
