Abstract
Lyrodus turnerae n. sp., a species of Teredinidae, is described from specimens in tropical Australia and Papua New Guinea. The new species is characterized by the morphology of the pallets, with a dark periostracal cap sharply descending into a thin calcium cup. New and existing collection records of L. turnerae are presented, indicating a distribution range from coastal Papua New Guinea and the Bismarck Archipelago, extending along eastern Australia to New South Wales.
