I'm pretty sure this is a species of Herviella, a genus of about ten or so small species usually with black specks and a gold or orange band below the ceratal tip. The cerata are arranged in a series of sloping single rows down each side of the body

Hello Dr.Rudman,
I have recently gone from Japan to the Philippines, for scuba diving. While there, I photographed this uncommon sea slug, Herviella sp.1. There wre two animals, both on the hydroid Aglaophenia whiteleggei. It was so small and very pretty.

Dear4 Yukari,
This is an interesting find, and from your photos and earlier messages it looks like this species is probably restricted to Aglaophenia whiteleggei. Could you give me a length please?
Thanks,
Bill Rudman

I'm pretty sure this is a species of Herviella, a genus of about ten or so small species usually with black specks and a gold or orange band below the ceratal tip. the cerata are arranged in a series of sloping single rows down each side of the body. As there has not been much published on them it is fairly easy to list the major references.
