Glycymeris marwicki, a new name for Glycymeris reevei Marwick, 1931 (Pteriomorphia: Bivalvia)

Abstract As part of his monographic study of the Tertiary Mollusca of the Gisborne district of North Island, New Zealand, Marwick (1931: 58) described a new glycymeridid, which he called Glycymeris reevei, from the Middle Miocene Tutamoe Formation. Unfortunately, the specific name reevei is preoccupied in the Recent Philippine species Glycymeris reevei (Mayer 1868: 23, as Pectunculus), a name in general used among Japanese and Filipino malacologists. We are not aware of any junior synonym of Marwick’s species, and, therefore, we propose to provide the name Glycymeris marwicki for Glycymeris reevei Marwick, non Mayer.
