Hello, I cant deterrmine this bivalve I believe to be a Veneridae.
It come from Mauritius and measures 18mm. Any help is appreciated.
Thanks

Looks to me like a Lioconcha species, other than that I can't help.

Could be Gomphinella undulosa (Lamarck 1818).

Thanks
Mike, G undulosa is from Southern Australia, that one is from tropical InfoPacific.
It might well be a Gomphinella, do you know an other species that could match ?

To me it resembles Lioconcha hieroglyphia
Juvenile perhaps?

Maybe    " Lioconcha ( Lioconcha ) ornata " ( L.W.Dillwyn 1817 )
Read Sea - Philippines

Well, my book also says that Gomphinella undulosa is from Australia.. but your shell looks very similar to this species. Maybe it is some other species of Gomphinella.

I don't think this is a Lioconcha though. Lioconcha shells shouldn't have a clearly visible pallial sinus (adductor muscle scar). See <!-- m --><a class="postlink" href="ftp://ftp.fao.org/docrep/fao/009/w7191e/w7191e29.pdf">ftp://ftp.fao.org/docrep/fao/009/w7191e/w7191e29.pdf</a><!-- m -->
