"This individual is special because its rhinophoral clubs are translucent yellow with a blue tip โ a colour pattern supposedly found only in the closely related species Tambja victoriae. So the distinction between Tambja affinis and Tambja victoriae now rests on the rather arbitrary choice of rhinophore sheath completely pale greenish yellow [as in this photo] (= Tambja affinis) or rhinophore sheath with a broad pale blue green marginal band (= Tambja victoriae)."
