  • 📠 This subspecies was automatically created by the valid publication of Aquaspirillum peregrinum subsp. integrum (Terasaki 1973) Terasaki 1979 (Approved Lists 1980) according to rule 40d.

  • ❗ Aquaspirillum peregrinum subsp. peregrinum is the correct name instead if this subspecies is regarded as a separate subspecies (i.e., if its nomenclatural type is not assigned to another subspecies whose name is validly published, legitimate and not rejected and has priority) within a separate species Aquaspirillum peregrinum within a separate genus Aquaspirillum.
