Comment from Nathalie Yonow:
Phyllidiopsis xishaensis is well known throughout the Indo-Pacific as Phyllidiopsis striata Bergh, 1889. This is a misnomer as
Phyllidiopsis striata Bergh, 1889 is a valid species, in the genus Phyllidiella as Phyllidiella striata (Bergh, 1889) [Phyllidiopsis] and clearly different, more similar to Phyllidiella rosans.
This species was posted on 12 July 2003 on these websites as Phyllidiopsis striata Bergh, 1889. I changed it on 28 September 2010 into
Phyllidiopsis xishaensis (Lin, 1983) [Phyllidia].
Pretty similar are:
Phyllidiopsis annae which has black rhinophores and a granular blue mantle with a blue mantle margin and 4 black lines. The 2 median black lines unite between the rhinophores.
Phyllidiopsis phiphiensis which has black rhinophores, 2 low white ridges on the mantle with a white mantle margin with black spots and 3 black lines. This species was first reported from the Phi Phi Islands, Thailand and not yet from the Philippines.
Phyllidiopsis sphingis which has white rhinophores, 3 low white ridges on the mantle with an iridescent blue broad margin and 4 black lines with black rays extending to the mantle edge. The 2 median black lines unite between the rhinophores.
