Interim Register of Marine and Nonmarine Genera

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.[1] The database aspires to provide complete coverage of both accepted and unaccepted genus names across all kingdoms, with a subset only of species names included as a lower priority. In its March 2019 release, IRMNG contained 490,095 genus names, of which 236,514 were listed as "accepted", 120,194 "unaccepted", 7,391 of "other" status i.e. interim unpublished, nomen dubium, nomen nudum, taxon inquirendum or temporary name, and 125,996 as "uncertain" (unassessed for taxonomic status at this time).[2] The data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. The data include homonyms (with their authorities), including both available (validly published) and selected unavailable names.[3]

IRMNG was initiated in 2006 by the Ocean Biogeographic Information System (OBIS) Australia at CSIRO Marine and Atmospheric Research, and subsequently has been hosted by the Flanders Marine Institute (VLIZ) from 2016 onwards.[1][4] VLIZ also hosts the World Register of Marine Species (WoRMS), using a common infrastructure.[5]

Content from IRMNG is used by several global Biodiversity Informatics projects including Open Tree of Life,[6] the Global Biodiversity Information Facility (GBIF), [7] and the Encyclopedia of Life (EOL),[8] in addition to others including the Atlas of Living Australia[9] and the Global Names Architecture (GNA)'s Global Names Resolver.[10] 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.[11] IRMNG identifiers have also been associated with numerous Wikipedia taxon pages, based on content harvested from IRMNG and stored in Wikidata.[12]

IRMNG was initiated and designed by Tony Rees.[1][13] For his work on this and other projects, GBIF awarded him the 2014 Ebbe Nielsen Prize.[13] The citation said, in part:[13]

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 currently (2019) managed and curated by Rees, with assistance from the VLIZ team.[1]

Flanders Marine Institute

The Flanders Marine Institute (Dutch: Vlaams Instituut voor de Zee, VLIZ) provides a focal point for marine scientific research in Flanders, northern Belgium.

The Flemish government established the institute in 1999 together with the province of West Flanders and the Fund for Scientific Research.

VLIZ promotes the accumulation of knowledge and excellence in research with regard to the ocean, seas, coasts and tidal estuaries. The central focus is on the provision of services to the research community, educators, the general public, policymakers and the industry.

VLIZ promotes and supports Flemish marine research. Within this scope, VLIZ focuses on open, useful networking and the promotion of an integrated and cross-disciplinary approach. VLIZ serves as a national and international point of contact in the field of marine research. In this respect, it supports the image of Flemish marine research in the four corners of the globe and can hold mandates to represent this research landscape.

The institute also supports and accommodates international organisations on behalf of the Flemish government: the IOC Project Office for IODE, the European Marine Board secretariat and the European Marine Observation and Data Network (EMODnet) secretariat in Ostend, and the Joint Programming Initiative on Healthy and Productive Seas and Oceans (JPI Oceans) secretariat in Brussels.

VLIZ also manages RV Simon Stevin a marine research vessel.

Making the research vessel Simon Stevin, marine robots as well as other research equipment and infrastructure available is one of the services provided to marine scientists in Flanders. Within a European context, VLIZ offers technical and operational expertise for the use of this infrastructure. It stimulates and initiates research based on these innovative technologies.

VLIZ also develops data systems, products, technologies and infrastructure. It collects new data by means of innovative techniques and valorises the increasing volume of marine data for the benefit of researchers, policymakers and the industry. In partnership with Flemish research groups, it develops permanent measurement networks at sea and presents itself to the world as a high-quality oceanographic data centre. The institute has developed and hosted the World Register of Marine Species and associated taxonomic subregisters, and hosts the Interim Register of Marine and Nonmarine Genera, and the Sea Level Monitoring Facility of the Global Sea Level Observing System. In November 2011 VLIZ was officially recognized as a World Data Center by the Paris-based International Council for Science (ICSU).VLIZ manages an extensive collection of marine scientific literature in Flanders and makes it publicly available to the broadest possible target group via its library. The Open Marine Archive makes it possible to remotely consult tens of thousands of publications free of charge. In addition, VLIZ initiates and conducts innovative and multidisciplinary research in collaboration with and complementary to the Flemish and international marine research groups. By identifying needs and opportunities, it provides oxygen to the Flemish marine knowledge economy of the future. VLIZ develops policy-relevant products and services for the marine research community and policymakers as well as to support the blue economy. The ‘Compendium for Coast and Sea’ is a reliable guide listing who does what within this field in Flanders. VLIZ initiates, promotes and supports multidisciplinary research to fill knowledge gaps and provide a basis for marine policy. It does so in close cooperation with the Flemish marine research community. Finally, VLIZ reaches out to the public at large, the press, educators and coastal guides. The information desk offers knowledge presented in innovative formats and contributes to increasing ocean literacy by means of science popularisation, thus improving the image of the research conducted in Flanders and beyond.


A genus (, pl. genera ) is a taxonomic rank used in the biological classification of living and fossil organisms, as well as viruses, in biology. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus.

E.g. Panthera leo (lion) and Panthera onca (jaguar) are two species within the genus Panthera. Panthera is a genus within the family Felidae.The composition of a genus is determined by a taxonomist. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful:

monophyly – all descendants of an ancestral taxon are grouped together (i.e. phylogenetic analysis should clearly demonstrate both monophyly and validity as a separate lineage).

reasonable compactness – a genus should not be expanded needlessly; and

distinctness – with respect to evolutionarily relevant criteria, i.e. ecology, morphology, or biogeography; DNA sequences are a consequence rather than a condition of diverging evolutionary lineages except in cases where they directly inhibit gene flow (e.g. postzygotic barriers).Moreover, genera should be composed of phylogenetic units of the same kind as other (analogous) genera.


Globularia is a genus of about 22 species of flowering plants in the family Plantaginaceae, native to central and southern Europe, Macaronesia, northwest Africa and southwest Asia. They are dense low evergreen mat-forming perennials or subshrubs, with leathery oval leaves 1–10 cm long. The flowers are produced in dense inflorescences (capitula) held above the plant on a 1–30 cm tall stem; the capitula is 1–3 cm in diameter, with numerous tightly packed purple, violet, pink or white flowers.Globularia species are used as food plants by the larvae of some Lepidoptera species including Coleophora virgatella.

Several members of the genus, such as Globularia cordifolia and Globularia punctata, are cultivated and sold for garden use.

Under the old Cronquist system of plant classification, they were treated in their own family, Globulariaceae, but genetic evidence has shown that the genus belongs in the family Plantaginaceae.

Most species are known as globe daisies or globularias.


Insulochamus is a genus of beetle in the family Cerambycidae. It contains the following species:

Insulochamus annobonae (Aurivillius, 1928)

Insulochamus fulvisparsus (Gahan, 1888)

Insulochamus thomensis (Jordan, 1903)


Leptomitales are an order of water moulds within the class Oomycetes that contains the genus Apodachlya.

Mordellistenoda ohsumiana is a species of beetle in the genus Mordellistenoda of the family Mordellidae. It was described in 1957.


Parechelus is an extinct genus of prehistoric bony fish that lived during the Ypresian (lower Eocene). The genus was circumscribed by Edgard Casier in 1967 for his description of P. Parechelus.When Casier circumscribed this genus, he simultaneously circumscribed the family Parechelidae which had Parechelus as its sole genus; he placed it in the order Anguilliformes. The family Parechelidae was supposedly intermediate between Ophichthidae and Muraenidae. Jack Sepkoski, citing Colin Patterson, also classified the genus in Anguilliformes.
