A Taxonomic Catalogue of the Nemerteans (Phylum Nemertea) of Spain and Portugal

16 pages, 4 figures, 2 tablesA literature-based taxonomic catalogue of nemerteans (phylum Nemertea) from Spain and Portugal is provided, listing 75 species (12 Palaeonemertea, 24 Pilidiophora, and 39 Hoplonemertea) belonging to 34 genera. 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 aspectsThis research has benefited from funds from the Instituto de Estudios Ceutíes, Ceuta, Spain. The study was also supported by the Franklin Institute, Universidad de AlcaláPeer Reviewe
