Cementation in the freshwater bivalve family Corbiculidae (Mollusca: Bivalvia): a new genus and species from Lake Poso, Indonesia

Article

Abstract

A species from Lake Poso, Indonesia represents the first instance of cementation in the freshwater bivalve family Corbiculidae. Posostrea anomioides gen. nov., sp. nov., which is cemented indifferently by its left or right valve to calcareous rocks, reaches a size of 16 mm. It has typical corbiculoid dentition, with serrated lateral teeth, and juveniles are brooded primarily in the inner ctenidia. Lake Poso occupies a tectonic fault in central Sulawesi. Posostrea adds to an interesting radiation of endemic fishes and molluscs, including the gastropod genera Miratesta and Tylomelania.
