The Interim Register of Marine and Nonmarine Genera (IRMNG) is a taxonomic database containing the scientific names of the genus, species, and higher ranks of many plants, animals and other kingdoms, both living and extinct, within a standardized taxonomic hierarchy, with associated machine-readable information on habitat (e.g. marine/nonmarine) and extant/fossil status for the majority of entries. The database aspires to provide complete coverage of accepted genus names across all kingdoms, with a subset only of species names included as a lower priority. As of December 2018, the number of names at all ranks reported by IRMNG to be included in the database was 2,299,581, of which 361,728 were listed as accepted genera, with a further 127,357 unaccepted genus names as at March 2018. The data originate from a range of (frequently domain-specific) print, online and database sources, and are reorganised into a common data structure to support a variety of online queries, generation of individual taxon pages, and bulk data supply to other biodiversity informatics projects. IRMNG content can be queried and displayed freely via the web, and download files of the data down to the taxonomic rank of genus as at specific dates are available in the Darwin Core Archive (DwC-A) format.
IRMNG was initiated in 2006 by the Ocean Biogeographic Information System (OBIS) Australia at CSIRO Marine and Atmospheric Research, and since has been hosted by the Flanders Marine Institute (VLIZ) since 2016. VLIZ also hosts the World Register of Marine Species (WoRMS), using a common infrastructure.
Content from IRMNG is used by several global Biodiversity Informatics projects including Open Tree of Life, the Global Biodiversity Information Facility (GBIF),  and the Encyclopedia of Life (EOL), in addition to others including the Atlas of Living Australia and the Global Names Architecture (GNA)’s Global Names Resolver. From 2018 onwards, IRMNG data are also being used to populate the taxonomic hierarchy and provide generic names for a range of taxa in the areas of protists (kingdoms Protozoa and Chromista) and plant algae (Charophyta, Chlorophyta, Glaucophyta and Rhodophyta) in the Catalogue of Life.
IRMNG in particular has been a tool of enormous importance to GBIF and others in supplying much of the detail for a global taxonomic classification of all life and as high-value taxon trait data in a form which can readily be reused in data validation and to enhance species pages.
IRMNG is now managed and curated by Rees, with assistance from the VLIZ team.
