Pruvotfolia pselliotes? from Dakar [2]

Dear Bill,
Following on from my other message - I think this animal from Dakar is also Pruvotfolia pselliotes. I think this one is juvenile. All of them were found under stones.

Location: Senegal, Eastern Atlantic
Site: M'bao
Depth: 6m
Size: 5-6mm

Dear Marina,
I am pretty sure this is an aeolidiid not a glaucid. If you compare the way the cerata are arranged in this animal with the way they were arranged in your other message, you will see it is quite different. In your earlier photos the cerata were arranged in two major groups, one in front of the heart and one behind it. If you could push some of the cerata aside you would have seen that the cerata were arranged in close, almost vertical rows, 5-7 rows on each side in front of the heart. Behind the heart there are 10 or more rows arranged into 3 or 4 clusters on each side. The clusters are difficult to separate in the living animal. The other distinctive feature in Pruvotfolia is that it is only the innermost cerata in each row which are very long and curled.

In the animal in this message, the cerata are arranged in well-spaced groups. I can't see all the detail but I suspect at least the anterior ones on each side are arranged in an inverted V-shape. Also all the cerata are of similar length. It is therefore most unlikely that this is Pruvotfolia. My feeling is that it is a juvenile Spurilla neapolitana.
Best wishes,
Bill Rudman
