|Classification according to Bouchet et al. (2017)|
Taxonomic source: World Register of Marine Species (AphiaID: 139599).

- Phyllaplysia brongniartii (Blainville, 1823)
- Phyllaplysia paulinoi Mazzarelli, 1893
The size of this species varies between 15 and 35 mm, although it has been cited a specimen of 50 mm in length. The body is flattened, somewhat narrower in the anterior side, and the outline is rounded or oval, shaped like a leaf. The coloration is variable but in most animals concentric green or gray bands can be seen on a white background. There are also white stain formed by groups of spots of the same color, aligned with the green or grey bands. The head is small and the rhinophores are green, they can also have a clear line in continuation of the ones on the back; anterior tentacles and rhinophores are rolled and the eyes are located before them. The parapodia are very poorly developed and completely cover the dorsal mantle. The mouth has a pair of short oral tentacles. The shell is rather flat, translucent, fragile and with growth striations.
Very little is known about the biology of this species besides it has long been confused with Petalifera petalifera. The specimens have been observed on algae and phanerogame seagrass like Posidonia oceanica and Cymodocea which they are supposed to feed on.
- Phyllaplysia. From Greek “phyllon”, leaf + “aplysia”, sponge, dirty.
- Lafonti. Dedicated to Alexandre Lafont, who published on cephalopods at least between 1869-71 and may possibly (but perhaps not likely) be the same A. Lafont, who is honoured in the bryozoan name Savignyella lafontii (Audouin, 1826).
After its description in the French Atlantic coast in Arcachon Bay (Fischer, 1872) it has been observed in the Strait of Gibraltar and the Mediterranean Sea, also in Madeira and very recently in Tufia, Gran Canaria (3/09/2016, J.J.Calderín Peñate, pers.comm.). There are photographs and reports from the same species in the Indo-Pacific (Philippines, Japan, Hawaii, French Polynesia) that should be confirmed by molecular analysis. In Catalonia it has been observed in the Mateua Island, the Medes Islands and Cala Aiguafreda.
