- 🫡 This name is on the List of Recommended Names for bacteria of medical importance (LoRN) as 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 not taxonomically suspended any more in favour of Corynebacterium nigricans Shukla et al. 2004.

- 🧍 According to Rules 27(3) and 30, this new species is not validly published, because the protologue of the effective publication makes reference to the deposit of the type strain in a single recognized culture collection. However, another recognized culture collection in a different country is cited in the abstract. According to the Judicial Opinion 81, Corynebacterium aurimucosum Yassin et al. 2002 is to be considered to be validly published. Publication: Euzeby JP, Tindall BJ.
