First supplement to the checklist of mesostigmatic mites of the Netherlands (Acari: Mesostigmata)

Sampling biotopes which are usually ignored yielded 23 species of Mesostigmata to be added to the checklist of the Netherlands. These biotopes are washed ashore debris and algae along the coast, banks of small seepage brooks, soil and litter of mineral-rich forests, ant nests, decaying mushrooms, alder forest and moist grasslands. Also two species know as commensals or parasites are added.
