A world checklist of Proseriata and Kalyptorhynchia - Rhabditophora, compiled by taxonomic experts and based on peer-reviewed literature. more

Freeliving flatworms (Turbellaria) are a very species-rich group of hermaphroditic organisms, occuring in marine, freshwater and even semi-terrestrial habitats. About 6200 species of free-living flatworms have been described, but this is a large underestimate of the actual number that probably exists. Despite their important role in the ecology of marine ecosystems and their abundancy both in number of individuals and in number of species, turbellaria are a very little studied group. This is partly because of the fact that they are considered difficult to identify. To enhance the study of turbellaria and to facilitate their identification, a database was developed at the Research Group Biodiversity, Phylogeny of the University Hasselt, in close cooperation with the Flanders marine institute (VLIZ). The end goal of this database is to cover all Rhabditophoran flatworms, providing figures of habitus and important details of the anatomy, literature data and information on distribution. At the moment, only the taxa Eukalyptorhynchia and Proseriata are completed and made accessible. This database is also an addition to the database developed by Seth Tyler and collaborators (, to which members of the research group Biodiversity, Phylogeny and Population studies also have contributed.
