Belongs within: Veneridae.

Paphia is a genus of bivalves that first appeared in the Oligocene, and is found primarily in the Pacific region, extending to Europe (Cox et al. 1969). The subgenus Callistotapes has the cardinal teeth of the hinge more divergent than in the type, with the left posterior cardinal much closer to the ligamental nymph (Marwick 1927).

Characters (from Cox et al. 1969): Elongate, compressed, shell surface glossy; hinge plate narrow; lateral teeth wanting.
