• Notes:
  • ⏰ According to Kurup and Agre (1983), this species is an earlier heterotypic synonym of Micropolyspora faeni Cross et al. 1968 (Approved Lists 1980). Publication: Kurup VP, Agre NS. Transfer of Micropolyspora rectivirgula (Krasil'nikov and Agre 1964) Lechevalier, Lechevalier, and Becker 1966 to Faenia gen. nov. Int. J. Syst. Bacteriol. 1983; 33:663-665.
  • ❗ Micropolyspora rectivirgula is the correct name instead if this species is regarded as a separate species (i.e., if its nomenclatural type is not assigned to another species whose name is validly published, legitimate and not rejected and has priority) within a separate genus Micropolyspora.
