The Interim Register of Marine and Nonmarine Genera (IRMNG) is a taxonomic database which attempts to cover published genus names for all domains of life (also including subgenera in zoology), from 1758 in zoology (1753 in botany) up to the present, arranged in a single, internally consistent taxonomic hierarchy, for the benefit of Biodiversity Informatics initiatives plus general users of biodiversity (taxonomic) information. In addition to containing over 500,000 published genus name instances as at July 2024 (also including subgeneric names in zoology), the database holds over 1.7 million species names (1.3 million listed as "accepted"), although this component of the data is not maintained in as current or complete state as the genus-level holdings. IRMNG can be queried online for access to the latest version of the dataset and is also made available as periodic snapshots or data dumps for import/upload into other systems as desired. The database was commenced in 2006 at the then CSIRO Division of Marine and Atmospheric Research in Australia and, since 2016, has been hosted at the Flanders Marine Institute (VLIZ) in Belgium.
