Hello Bryony,

Not sure if this will be much help. First Michel Bhaud is very expert in id from plankton, but perhaps such a problem these days could be tackled molecularly? Is there any data in GenBank? However, noting David Kirtley thought there might be "more than one definable species" under the name 'spinulosa'.

I imagine you have reviewed the lit specifically on development of the species (DP Wilson, et al), but anyway for general European plankton this paper is good if you have not seen it:

Bhaud, M.; Cazaux, C. (1987). Description and identification of polychaete larvae, their implications in current biological problems. Oceanis. 13(6): 595-753. 

And I wonder if Gunnar Thorson covered that species (haven't got my copy handy) in his magnum opus? 

Thorson, G. (1946). Reproduction and Larval Development of Danish Marine Bottom Invertebrates, with Special Reference to the Planktonic Larvae in the Sound (Oresund). Meddlelser fra Kommissionen for Danmarks Fiskeri-og Havundersogelser,Serie Plankton 4(1): 1-523.

Good luck,

Geoff Read
