De stille opmars van de hooiwagen Dicranopalpus ramosus in Nederland (Arachnida: Opiliones)

After a first record for the Netherlands of Dicranopalpus ramosus (Simon, 1909) in 1993 there is a sudden increase of records in and around the city of Nijmegen in 2004. Diagnostic characters for easy distinction from other opilionids are given. The species is classified as of submediterranean-atlantic origin and its present distribution in Europe and the Netherlands is outlined. Details of the life cycle and habitats are given. D. ramosus, as a newly arrived species, does not seem to restrict itself to anthropogene habitats (walls of houses etc.) but is also found in a variety of other situations (shrubs and herbal vegetation). Other species of harvestmen with which it shares the habitat are mentioned.
