    "Selenomonas massiliensis" Belkacemi et al. 2018	homotypic synonym, not validly published

• Notes:
  • 🧍 Considered not validly published. The authors proposed the species as a Candidatus name. This is not in accordance with Rule 69(1)(a) because the authors did not demonstrate that the culture does not fulfil the requirements of Rule 30. Assume a culture could be deposited in accordance with Rule 30(4) in two culture collections in two different countries, but this has simply not been done. If so, the culture itself may meet the requirements of Rule 30; it is just that the deposits would not. The name is not pro-validly published either.
