Abstract

Chama iudicai n. sp. is described from the Pleistocene of San Antonio Oeste, Rio Negro Province, Argentina. It is characterized by its large size, thick shell, and crenulated inner margin. Externally it has weak comarginal lamellae. It is indicative of a clear, stenohaline, warm-water environment. This is the first record for the family Chamidae in the Argentine Quaternary.
