| Abstract | Species of the bivalve family Lucinidae form a previously unrecognized and significant component of bivalve assemblages at bathyal depths (150-1000 m) in the Indo-West Pacific province. Elliptiolucina labeyriei n. gen., n. sp., from 2570 m, is the deepest-occurring lucinid species. South-East Asian seas, from Taiwan to the Arafura Sea, are a hotspot of deep-water lucinid diversity, with 11 species recorded from the Philippines and 14 from Indonesia. Numerous species are in the 20-50 mm range, with several up to 75-80 mm in size, and Meganodontia acetabulum reaches 150 mm. Several species co-occur with representatives of the Vesicomyidae, characteristic of seep and vent communities. It is hypothesized that the lucinid species of this radiation live in discrete pockets of poorly oxygenated sediments enriched in sulfide by plant debris from nearby land masses and/or diffuse seeping. A parallel is drawn with the “Calcari a Lucina” from the Miocene of Europe. Nine new genera and 32 new species are described. |
