Hello Ana,

It is difficult to give an answer when the identifications are only to genus 
(or family) because the mode can vary within the genus. You might find some 
help in this paper:

Wilson, W. H. 1991: Sexual reproductive modes in polychaetes: Classification 
and diversity. Bulletin of Marine Science 48: 500-516.

Or try a review such as: 
Schroeder, P. C. 1989: Annelida: Polychaeta. In K. G. Adiyodi ; R. G. Adiyodi 
(ed.) Reproductive Biology of Invertebrates, Vol. 4. Fertilization, 
development, and parental care, Part A. xxiii+ 463. Chichester, England, New 
York. John Wiley and Sons Ltd. p. 383-442.

And papers in Hydrobiologia 402 such as Blake, J. A. ; Arnofsky, P. L. 1999: 
Reproduction and larval development of the spioniform Polychaeta with 
application to systematics and phylogeny. Hydrobiologia 402: 57-106.

Halodsynella australis seems to be a misspelling of Halosydnella australis 
(Kinberg) in Polynoidae. I could find no information on its reproduction.

Neanthes succinea has over a hundred citations in my literature database. As 
far as I know its reproduction is via a short duration planktonic larva, 
probably feeding only when settled.

Cheers,
