An uncommon Cardiidae? Carditidae?

[conchylinet]

Dear All,
I recently found this bivalve beached on the West Coast of Mauritius (SW Indian Ocean) and could not identify it. It is 32mm long.
I started to go for a Plagiocardium, but it does not match P. setosum from this area. Perhaps a Venericardia from the Carditidae family?

Anybody can help?
