Key to the genera of the family Epsilonematidae

This identification key for the genera of the family Epsilonematidae should serve as a help in the difficult process of identifying members of this family. The key is based upon literature sources and the experience of several Nematologists from the Marine biology Section Ugent. Note that the key is an evolving tool.
Using the key still requires a basic skill in the field of nematology. Results should always be checked with the species-descriptions and illustrations available in the database.
