Pliocardia cf. donacia (Dall, 1908)

Examined material.

1 valve EA337 (1.7811°N, 79.0351°W) at 530 m (INV MOL9768), 1 valve EA336 (1.9045°N, 79.3030°W) at 612 m (INV MOL9770), 1 live specimen EA344 (2.3905°N, 78.8288°W) at 656 m (INV MOL9771).

New location.

Off Nariño, Colombian Pacific.

Distribution.

Panama ( Coan and Valentich-Scott 2012), Choco, Colombia ( Gracia and Valentich-Scott 2014).

Remarks.

Prior to this study, dead shells of Pliocardia donacia were identified in Pacific Colombia at depths between 272 and 295 m ( Gracia and Valentich-Scott 2014). The present collection in southern Colombia yielded one live specimen and two empty valves, suggesting that the species inhabits both the northern and southern Colombian Pacific. Further, the bathymetric limit of the species is extended to 656 m in the Colombian Pacific. Many generic uncertainties exist within the family Vesicomyidae . Thus, we follow Coan and Valentich-Scott (2012) in their tentative placement of P. donacia within the genus Pliocardia .
