oribatid mites in the flevopark in amsterdam (acari: oribatida) Salih Doğan, Nusret Ayyıldız, Farid Faraji, Sibel Dilkaraoğlu, Erhan Zeytun & Firdevs Ersin The Flevopark is one of the most special green areas of Amsterdam with a rich nature. Twelve oribatid mite species were collected here in 2014 from bark and mosses on trees. Liacarus acutus and Perlohmannia dissimilis are reported for the first time from the Netherlands. It is not clear if the newly recorded species have always been overlooked or are recent immigrants. introduction Acariformes (Krantz & Walter 200, Yalçın et al. Mites (Acari) are small arthropods. They form an 203).

This species is not reported in the lists of the oribatid mites of the Netherlands (Van der Hammen 52, Siepel et al. 200), nor in later works carried out in the country (Siepel et al. 202, Siepel & Dimmers 200). We found one specimen, which therefore is the first record from the Netherlands. discussion Determining urban mite diversity is important because human developments cause rapid change to natural lands, and great losses in biodiversity.
