Aldisa sp. 04 is characterized by a translucent orange body colour, by small flat rounded whitish tubercles, and by two large excavations or 'pits' in the dorsal midline, one just behind the rhinophores, the other one in front of the gills. The excavations mimic a sponge oscule. The rhinophores are bright orange, the gills are greyish-tan. There are small white spots on the mantle, some arranged to whitish patches.
It looks somehow similar to Aldisa sp. 4 in IPN at page 160 which differs by the dark red body colour and by opaque white gills.
Dr. Alicia Hermosillo McKowen labelled it 'Dorido amarillo 2.JPG'.
NUDIPIXEL has a picture of a similar specimen from Taiwan which is for sure IPN Aldisa sp. 4!
R.F. Johnson (2011) moved the genus  Aldisa  Bergh, 1878 from the family Dorididae  Rafinesque, 1815 to the resurrected family Cadlinidae  Bergh, 1891.
