Dendrodoris atromaculata (Alder & Hancock, 1864) [Doridopsis]

Let me quote the description of Dendrodoris atromaculata from IPN at page 281, reference below: "Dorsum covered with complex tubercles, each with a narrow stalk and a swollen midsection bearing many finger-like papillae which radiate out in a stellate pattern. Body pale yellow to brownish-orange with irregular dark brown patches."
Very similar and very variable is Thordisa villosa (Alder & Hancock, 1864) [Doris], I don't know how to distinguish them.
This picture was posted at these websites on 21 June 2004 as Dorididae sp. A, then changed into Discodorididae sp., I noticed on 17 September 2010 that Jeffrey Rosenfeld had changed its name and labeled it Thordisa villosa.
I was not convinced of this identification, because all pictures of Thordisa villosa at the web look pretty different, and it differs from the description,
but I also changed the name into Thordisa villosa (Alder & Hancock, 1864) [Doris]
on 13 July 2011 I noticed, that Jeffrey Rosenfeld had changed its name again and labeled it then Dendrodoris atromaculata,
I searched the internet and:
the picture from Terry Gosliner at NYTimes.com which is for sure the same species and is labelled Dendrodoris atromaculata convinced me, though the picture of Dendrodoris atromaculata in IPN, which is also at the fact sheet of the Sea-Slug Forum looks different!
I changed it again on 13 July 2011 into Dendrodoris atromaculata (Alder & Hancock, 1864) [Doridopsis].
