Is this Phyllidiopsis krempfi?

Locality: Tanjung Nibong, Lang Tengah Island, 15 m, Malaysia, South China Sea, 27 July 2006. Length: 5 cm. Photographer: Kenneth Yong.

Thanks much for the help.

Dear Kenneth,
It certainly looks like P. krempfi, but my only doubt is that in species of Phyllidiopsis the rhinophores are usually multi- or bi-coloured and never completely black. On the other hand, species of Phyllidiella, have black rhinophores. In P. krempfi, the rhinophores are usually black with a pink band up the anterior side, wide at the base and getting narrower towards the tip. The rhinophores are half retracted in your animal, but I would have expected to see a bit of pink. On the other hand I don't know of a species of Phyllidiella that looks like this.

Best wishes,
Bill Rudman
