Laevichlamys Waller, 1993: 204. Type species (by original designation): Pecten multisquamatus Dunker, 1864. Recent, tropical western Atlantic.
Diagnosis. Non-cemented or embedded Pedini with weak radial costae or riblets (evenly or unevenly spaced), shagreen microsculpture secondarily absent from most specimens, intercalated antimarginal striae, commarginal ridges absent, byssal notch shallow to deep, ctenolium well-developed, hinge teeth weak.
Distribution. Upper Miocene–Recent (Waller, 1993: 204). Western Atlantic and Indo-West Pacific, living in the subtidal to sublittoral zones.
Discussion. Waller (1993: 204) created a new genus for the chlamydoid taxa with weak to almost smooth macrosculpture. Most of the representative extant species live in the Indo-West Pacific, the exception being the type species (see above).
