It was originally posted at these websites as Platydoris sp. D Genus: Genus: Bergh, 1877.
For some genera, such as Trinchesia was the alphabet almost through. I had to change the distinguishing alphabetic character into a number. I have chosen 2-digit numbers, even though '01' looks a little bit stupid, and now is only the genus italic written.
