Hi Doug,
I don't think anyone has proposed that. I'm relying on the Norlinder et al paper, but there may be something later I've missed. There is a prior sigalionid subfamily. Pettibone made SF Pelogeniinae the container mainly for a set of sigalionid genera she created for the sand-encrusted sigalionids. Not sure how those would stand up if anyone looked at the molecules - but they may.
Norlinder, E., Nygren, A., Wiklund, H. and Pleijel, F. (2012). "Phylogeny of scale-worms (Aphroditiformia, Annelida), assessed from 18SrRNA, 28SrRNA, 16SrRNA, mitochondrial cytochrome c oxidase subunit I (COI), and morphology." Molecular Phylogenetics and Evolution 65(2): 490-500.
That paper included only at Pisione and Pisionidens. However, Pisione is the big genus. The others are minor players.

Thanks Geoff.
Is it now properly in a subfamify the Pisioninae?
Cheers,

We have both momentarily forgotten the testimony of the molecules.
Best to think of the Pisionidae genera as in Sigalionidae 'scaleworms' now. But while hunting for literature they will be found as Pisionidae.

Dr. Smitha,
I agree with Geoff. Looks like a specimen of Pisionidae with possible male copulatory organs on that 16th segment.

Hi Dr Smitha,
The photos seem to be of a pisionid - family Pisionidae. The 16th seg structures are presumably copulatory organs of a male.
Cheers,
Geoff Read

Subject: Nereis expert
Dear all,
Any Nereis expert in our group?
I have got one Nereis sp. It has 22 segments and its 16th segment bears a pair of long parapodium compared to others. Referred a number of publications. But I am not able to identify the specimen.
Kindly help me for identify the specimen?
