Notes:
- ❗ Rickettsia heilongjiangensis 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 Rickettsia.
