As a suplement to the lists of the mites fauna of Turkey compiled by Özkan et al. (1988 and 1994), a faunistic list of mites (Arachnida: Acari) from Turkey is presented based on published data. The species are arranged alphabetically within orders and for each entrance the origin of reference to the published record is provided. Among the 504 taxa, 134 belong to the Gamasida, 2 to the Ixodida, 291 to the Actinedida, 7 to the Acaridida and 70 to the Oribatida.

The stigmaeid mites collected from Kelkit Valley in Turkey are investigated. Nine new species, Cheylostigmaeus urhani sp. nov., Eustigmaeus varius sp. nov., Ledermuelleriopsis indiscretus sp. nov., Stigmaeus additicius sp. nov., S. angustus sp. nov., S. ayyildizi sp. nov., S. furcatus sp. nov., S. kelkitensis sp. nov. and Prostigmaeus integrius sp. nov., are described and illustrated. The following four stigmaeid species are new records for the Turkish fauna: Cheylostigmaeus salinus Evans, Eustigmaeus lacuna (Summers), Stigmaeus glabrisetus Summers and S. solidus Kuznetsov. Some known stigmaeid mites are recorded from new localities. This is the first record of the genus Prostigmaeus Kuznetsov in Turkey. Keys to Kelkit Valley genera and species of Stigmaeidae are included.

Demodex mites are very prevalent in healthy individuals of both sexes, and this should be taken into consideration when epidemiological and clinical studies are conducted with patients having different dermatological ailments.
