Paradoris dubia and P. leuca

January 11, 2007
From: Bill Rudman

I recently noted Benoit Dayrat's comprehensive revision of the genus Paradoris [message #18271] when I was posting an inquiry about an animal from New Zealand that I identified as Paradoris leuca [message #18265 ]. In that message I noted I was unsure about Benoit's proposal to consider the New Zealand P. leuca to be a synonym of the southern Australian Paradoris dubia. All specimens of P. dubia which I have seen have a very distinctive pattern of dark rings on the mantle which surround compound glands. The only two photos of Paradoris leuca that I know of [both on the Forum] show no sign of these dark rings or the associated glands.

This is a genus in which there are few gross anatomical differences between species, so it seems to me that we should wait until more material of the New Zealand species is examined before we consider them to be a single species. I have been planning for some time to post a selection of photos of Australian specimens of P. dubia on the Forum and am at last able to say I have found the time. So as you will see by the many messages, today is almost exclusively a Paradoris dubia day

Best wishes
