Nieuwe vondsten van watermijten in Nederland (Acari: Hydrachnidia).

New records of water mites in the Netherlands (Acari: Hydrachnidia) Three species of water mite new to the fauna of the Netherlands are reported, i.e. Hydryphantes flexuosus, Panisus michaeli and Nilotonia borneri. Moreover, a number of new records of rare species is given. Re-identification of Dutch material previously reported as Sperchon glandulosus showed that all specimens belong to S. thienemanni. Furthermore Eylais tullgreni was added by Davids et al. (2005), which adds up to 242 species on the Dutch water mite list.
