Hello Elisa, Clara and Pierluigi,
Microclymene tricirrata Arwidsson is not relevant. It just happens to have the same species epithet, and also it was informally and mistakenly once put into Clymenura. The valid name for Bellan & Reys species is the original name, Leiochone tricirrata Bellan & Reys, 1967, from Mediterranean France.
Leiochone and Clymenura are maldanid genera with *ventral shields*, but are distinct as reassessed in a paper in this Zootaxa issue:
http://www.mapress.com/zootaxa/list/2011/2934.html
Quote: "All [Leiochone] lack cephalic plate rims and have reduced dentition in first chaetiger uncini, all have anal cones with three pygidial cirri (or cirri are absent in one species), and all except one have prostomial ocelli."
I will send you a copy of my paper separately, but WoRMS has existing notes on Leiochone/Clymenura that answer your question. Also I'm sure there is scope for further work on clarifying European Leiochone as material becomes available, but that's where we are at currently.
Cheers,
Geoff Read

Dear colleagues,
We need
help on the accepted name of a Maldanidae species.
We identified
the Maldanidae polychaete using the “Garwood, P. R. 2007. Family Maldanidae - A
guide to species in waters around the British Isles. NMBAQC 2006 taxonomic workshop,
Dove Marine Laboratory”.
It has 3
cirri originating from a broad muscular ring forming a pygidial plate and anal
cone present, with a well developed ventral valve.
We found
this species 60 km offshore the coast of Marche Region (Northern Adriatic Sea,
Italy) at 60m depth, on sandy bottoms.
The key (Garwood, 2007) indicated it as Clymenura tricirrata
but now this name is not accepted in WoRMS Portal. WoRMS indicated two
species as accepted name: Microclymene
tricirrata Arwidsson, 1906 and Leiochone tricirrata Bellan
& Reys, 1967.
Which is the corresponding name for our species?
Thanks a lot
Pierluigi, Clara e Elisa
