Hi Bill and everyone!
Well yet again the Sunshine Coast continues to reveal more species. Here is the 317th species found here! Thuridlla hoffae which appears to be another new record for sthn Queensland. Note the 'light blue band running parallel to the paradodial edge' is a series of broken blotches of brilliant blue.
It's nice for the 'Gentleman Scientists' to find yet another Thuridilla here.

I suspect this is T. livida rather then T. hoffae. When I used 'band' on the Fact Sheet to describe the blue on the parapodia I was trying to differentiate between the bright blue line found in T. livida and the more diffuse light or pale blue broad band seen in the photo on the T. hoffae Fact Sheet. In fact the original description describes the blue as 'blue-green blotches covering most of the parapodia' much like in Marina Poddubetskaia's animals [#11525].
Your animals are also a bit unusual in having a thin orange line midway down the parapodia, and the bright blue patch behind the rhinophores, but as I said in a comment on one of your other messages, it is early days in understanding colour variability in these new species of Thuridilla so every new photo is valuable, even if we can't be totally sure of their identity.
