Fimbria Mühlfeld, 1811: 52 .

TYPE SPECIES. — Fimbria magna Mühlfeld, 1811 (junior synonym of Venus fimbriata Linnaeus, 1758 ). (monotypy).

Ligament set in shallow groove. Hinge massive, with 2 cardinal teeth in each valve, a single, large anterior lateral tooth close to cardinals, with smaller posterior lateral located above posterior adductor scar.

REMARKS

Although often separated as a distinct family Fimbriidae (e.g., Chavan 1969), recent molecular analysis of Fimbria fimbriata indicates that it groups within a monophyletic Lucinidae ( Williams et al. 2004) .
