A new checklist of the Dutch spider fauna. An updated checklist of the spiders of the Netherlands is presented to replace the earlier one of 1993. The list can serve as a basis for names to be used in faunistic publications. Letter codes and numerical codes are presented to facilitate the registration of distributional data for the European Invertebrate Survey – Netherlands. The nomenclature follows the latest (1998) edition of “Advances in spider taxonomy” by Norman I. Platnick and more recent publication, if available. The high degree of present time efforts in spider taxonomy make future changes in nomenclature and taxonomic interpretations unavoidable.
