Genus Iravadia Blanford, 1867

TYPE SPECIES. — Iravadia ornata Blanford, 1867 , by monotypy ; Recent, India.

Ponder (1984) reviewed this family and admitted nine genera. Ponder (1994) described a new genus ( Lantauia ) from Hong Kong, the type species of which ( L. taylori Ponder, 1994 ) is unusual among iravadiids by its trochiform shape. Le Renard (1996) discussed the family as part of a revision of the Paris Basin Eocene malacofauna and introduced two new fossil genera. The Iravadiidae comprise 11 genera of which nine are recent: Iravadia (with four subgenera: Iravadia s.s., Chevallieria Cossmann, 1888; Pseudonoba Boettger, 1902 and Fairbankia Stoliczka, 1868), Rissopsis Garrett, 1873 , Hyala H. & A. Adams, 1852, Ceratia H. & A. Adams, 1852, Liroceratia Ponder, 1984 , Acliceratia Ponder, 1984 , Pseudomerelina Ponder, 1984 , Lantauia Ponder, 1994 ; and three exclusively fossil genera, Rhombostoma Seguenza, 1876 , Anteplana Le Renard, 1996 , Styloceratia Le Renard, 1996 .
