Orlovb, c aNational Research Tomsk State University, Tomsk, 634050 Russia bUniversity of Tyumen, Tyumen, 625003 Russia cUral State Medical University, Yekaterinburg, 620028 Russia *e-mail: [email protected] Received October 12, 2017 Abstract—New data are presented on the ectoparasite fauna of several species of vesper and horseshoe bats (Chiroptera: Vespertilionidae, Rhinolophidae) of the Crimean Peninsula. In the studied territory, 11 species of ectoparasites (mites and insects) have been collected from 6 bat species; 2 of the ectoparasite species were new to Crimea. Findings of gamasid mites Ichoronyssus scutatus on an unusual host are discussed. The gamasid mite Spinturnix emarginatus (Acari: Mesostigmata: Gamasina) is described for the territory of Russia for the first time.
