This is a low species number compared with the approximately 400 species listed in Europe. This lack of knowledge is mainly due to the low number of researchers interested in the phylum and the well-known taxonomic difficulties of its study. Geographic records are indicated for each species, and for some, comments are included on certain biological and taxonomic aspects.

Since the first nemertean species was Park (Junoy and Herrera-Bachiller, 2010). collected off Spain and Portugal, Euborlasia elizabethae (McIntosh, 1874), identification has been problematic.
