First supplement to the checklist of the astigmatic mites of the Netherlands (Acari: Oribatida:Astigmatina)

In this first supplement to the Dutch checklist of the Astigmatina, we add 43 species. Of these, six are free-living, three are associated with mammals and 34 live on birds, either as commensalistic feather mites or as parasites. Furthermore, we delete two species from the list and present additional records of two other species. The current total Astigmatina in the Netherlands is now 303. We might expect many more, because of the very diverse life histories of these mites, which resulted in a large speciation.
