• Notes:
  • The phylogenomic assignment score of this taxon is 0.00791 (N = 30).
  • Saccharopolyspora erythraea (Waksman 1923) Labeda 1987, comb. nov. was first described as Saccharopolyspora erythraea, sp. nov. Publication: Euzeby JP. List of Bacterial Names with Standing in Nomenclature: a folder available on the Internet. Int J Syst Bacteriol 1997; 47:590-592.
  • Rule 17 states that the type determines the application of a taxon if the taxon is subsequently divided or united with another taxon, and Rule 40b that the specific epithet must be retained for the species which includes the type strain. Since Saccharopolyspora erythraea Labeda 1987 contains the type strain of Streptomyces erythraeus (Waksman 1923) Waksman and Henrici 1948 (Approved Lists 1980), the taxon must be regarded as a new combination: Saccharopolyspora erythraea (Waksman 1923) Labeda 1987.
