  • ❗ Photorhabdus luminescens subsp. hainanensis 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 Photorhabdus luminescens within a separate genus Photorhabdus.
  • 😷 The risk group for Germany has been imported on 2023-10-29. The full classification is: risk group = 1, note = "n".
