Known only from southern Thailand (Andaman Sea, north-eastern Indian Ocean).
4-10 m depth, Phi Phi Island, southern Thailand, 25 Nov. 1989, dorsal view of 10 mm specimen on food sponge, Gellius sp. (Brunckhorst, 1993: Plate 8F).
Notes compiled from Brunckhorst, 1993:
Phyllidiopsis phiphiensis has the following distinctive external characteristics: two low, white ridges separated by three furrows lined with black; white mantle margin with black spots; white rhinophores; and white ventral coloration with black spots on the margin of the hyponotum and on the side of the foot.
There are three other, small, longitudinally striped species of Phyllidiopsis. Two of these, Phyllidiopsis annae and Phyllidiopsis sphingis, are easily separated from the present species because they possess blue pigmentation, grey gills and black (P. annae) or pale yellow (P. sphingis) rhinophores. Phyllidiopsis striata is less easily separated. However, P. striata has three low, white ridges and four black bands (two white ridges and three black bands in P. phiphiensis), lemon yellow rhinophores, and grey and black ventral coloration.

I photographed these Phyllidiopsis phiphiensis in the Mergui Archipelago, Andaman Sea, Myanmar. The upper image was shot at Western Rocky on Feb. 25, 2003 at about 10 meters. It appears to be feeding on a red sponge. It was 16 mm long. The slug in the lower image, also on
a red sponge, was shot at Three Islets on Feb. 27, 2003 at about 10 meters. It was 14 mm long. I also photographed the four-striped Phyllidiopsis striata in this area.

Dear Mary Jane,
Thanks for another interesting find. Brunckhorst (1993) reports this species feeding on a semitransparent white sponge of the genus Gellius.

This is Phyllidiopsis phiphiensis. It is the only species with three longitudinal black lines and colourless rhinophores.

It looks to me that my find is Phyllidiopsis striata. My first thought about this animal is P. annae but after I took a good look at its rhinophore I know it's not like what I think. The white rhinophores are a good indication that my humble find is P. striata. Still I need your advice on this.

Your 'humble' find is Phyllidiopsis phiphiensis, which was named after the very place in which you found it. Both P. strtiata and this species have whitish rhinophores but in Phyllidiopsis phiphiensis there are three black lines on the mantle while in P. striata the central one splits in two to form four lines.

Here are some more from Thailand: I am pretty sure both are Phyllidiopsis phiphiensis Brunckhorst, 1993.
They are from the Phi Phi Islands in Thailand!

They certainly look like P. phiphiensis to me and the Phi Phi Islands is definitely the right place to find them.
