Mimics of Phyllidiella pustulosa
Note added 5 March 2007: This species was previously known on the Forum as Discodoris? liturata Bergh, 1905
This remarkable mimic of the phyllidiid Phyllidiella pustulosa has been commented on by a number of researchers in recent years. Richard Willan ( message #350 ) has studied the holotype of Bergh's Discodoris? liturata and considers them to be the same, but not a species of Discodoris. Bergh's material was collected from off Sumbawa Island, Indonesia, during the Siboga Expedition. he notes its similarity to Phyllidiella.
Dayrat (2006) shows that it is a species of Paradoris.
