Notes:
- ⏲ According to Committee (2025), this species is a later heterotypic synonym of Corynebacterium kroppenstedtii Collins et al. 1998. Publication: Committee AH. Mitigating changes in prokaryotic nomenclature: Definitions and Workflow. Zenodo 2025; 2025:15320329.
- ❗ Corynebacterium pseudokroppenstedtii 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 Corynebacterium.
- 🎓 Name mentioned 5 times in PubMed until 2026-06-11.
- 🪓 Organisms assigned to this species have previously been classified as Corynebacterium kroppenstedtii Collins et al. 1998. Publication: Collins MD, Falsen E, Akervall E, Sjoden B, Alvarez A. Corynebacterium kroppenstedtii sp. nov., a novel corynebacterium that does not contain mycolic acids. Int J Syst Bacteriol 1998; 48:1449-1454. 🇬🇧 Anonymous. Notification list.

- 😴 This name is on the List of Recommended Names for bacteria of medical importance (LoRN) as a synonym of the name to be applied to this species. The name is on LoRN because of the recorded pathogenicity of the species itself. This name is taxonomically suspended (and therefore not recommended for medical use for now) until no later than 2027 in favour of Corynebacterium kroppenstedtii Collins et al. 1998.
