Chromodoris loringi from Port Stephens, NSW

Dear Bill,
We found this tiny nudibranch during a boat dive with Pro Dive Nelson Bay to Little Island. On the same dive we found a lot of Chromodoris woodwardae that you have already identified for us [message #15063]. We originally thought this one was the same but when the photos came back we could notice some differences that fitted with Chromodoris loringi. Can you confirm the identity of this one?

Dear Leanne & David,
Yes this is Chromodoris loringi. You are certainly finding a few of the less common red-spotted chromodorids of southeastern Australia. In fact my redescription of C. loringi (see Rudman, 1983) was the first report of the species since its description in 1864. A another red-spotted species which was misidentified by Tom Thompson (1972) as C. loringi, is what I named C. thompsoni. I note that the Fact Sheets for these species are rather lacking in information. I'll do my best to remedy that in the near future.
Best wishes,
Bill Rudman
