  • 🙄 This taxon name is occasionally misprinted (or affected by an OCR error) in some sources as: "Amphithria"; "Amphithrir"; "Amphitrix".
  • ❗ Amphithrix is the correct name instead if this genus is regarded as a separate genus (i.e., if its nomenclatural type is not assigned to another genus whose name is validly published, legitimate and not rejected and has priority).
