Reasoning recorded at review

• •Translucent to opaque white body
• •Three conspicuous collar-like lamellae clearly resolved on the translucent-black rhinophores
• •Orange to salmon digestive-gland field in the cerata
• •Black apical marking repeated across multiple cerata
• •The visible character combination matches the external diagnosis of Favorinus tsuruganus

Alternatives considered

• Other Favorinus species

  Why plausible: Egg-eating Favorinus can converge on pale bodies and coloured cerata

  Comparison: Anal position, radula and COI would confirm
