• Notes:
  • 🥇 Nomenclatural type of the genus Bacterionema Gilmour et al. 1961 (Approved Lists 1980). Publication: Gilmour MN, Howell AJ, Bibby BG. The classification of organisms termed Leptotrichia (Leptothrix) buccalis. I. Review of the literature and proposed separation into Leptotrichia buccalis Trevisan, 1879 and Bacterionema gen. nov., B. matruchotti (Mendel, 1919) comb. nov. Bacteriol Rev 1961; 25:131-141.
  • ❗ Bacterionema matruchotii 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 Bacterionema.
