Dear Erwin,
The short answer is yes. When I looked at this genus some years ago the only external differences I could match with anatomical differences were in body shape. I know in most chromodorids that colour is a very good indicator of species, but it doesn't seem to be so in Ceratosoma. We could of course be wrong.
Best wishes,
Bill Rudman.
