Click the thumbnail photos to enhance!

Aldisa sp. 02 is characterized by one pit or depression in front of the gills. The colour varies from orange to a dark brown with large whitish-tan patches. The rhinophores have the same colour as the body, the gills are tan. This picture shows an orange specimen and a brown specimen in the mating position.
The highly variable Sclerodoris tuberculata looks extremely similar, I don't know how to distinguish them, I think they are one species...
The specimens #1 and #3 were identified by Dr. Richard Willan, thanks!
This species was posted on 17 June 2011 at these websites as Aldisa sp. B  Genus: Bergh, 1878, and changed on 16 July 2011 into
Aldisa sp. 02  Genus: Bergh, 1878.
For some genera was the alphabet almost through. I had to change the distinguishing alphabetic character into a number. I had chosen 2-digit numbers, even though '01' looks a little bit stupid, and now is only the genus italic written.
R.F. Johnson (2011) moved the genus  Aldisa  Bergh, 1878 from the family Dorididae  Rafinesque, 1815 to the resurrected family Cadlinidae  Bergh, 1891.
