  • ❗ Serpens tuomuerensis 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 Serpens.
  • 🧬 The phylogenomic assignment score of this taxon is 0.22511 (N = 6).
  • 🎓 Name mentioned 0 times in PubMed until 2025-10-14.
  • 🙅 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 risk group of other species in the genus.
