Resumen:
Glycymeris sanmatiensis n. sp. is described and compared with G. longior
(Sowerby, 1832) and G. undata (Linnaeus, 1758). Its diagnosis is: shell
small, subcircular, valves weakly inflated. Posterior margin truncated.
Ligament area asymmetrical. Hinge plate wide. Inner ventral margin wide
and smooth between pallial line and crenulations.
The new species from the Pleistocene of Golfo San Matías (Patagonia,
Argentina) appears together with other warm-water species such as Chama
iudicai (Pastorino, 1991) and Tegula atra, suggesting warmer
sea-temperatures during this period.
