• During the summer 2010 several mist nettings for the monitoring of bat species were performed in Saxony-Anhalt. Captured individuals were tested for ectoparasitic infestation. The aim was to update the fauna of ectoparasites of this state and to collect data on the distribution of individual species. Regarding this, results of previous surveys are summarised. In the present study nine out of thirteen bat species were found to be infested with a total of one flea species, one species of bat flies and eight species of mites. The infestation with fleas was below the expectations. Six spinturnicid mite species out of those occurring in Germany could be ascertained for Saxony-Anhalt. These are Spinturnix acuminatus (Koch, 1836), S. andegavinus (Kolenati, 1857), S. helvetiae Deunff, Keller & Aellen, 1986, S. mystacinus (Kolenati, 1857), S. plecotinus (Koch, 1839) and S. puncata (Sundevall, 1833). Details about the infestation with parasites (abundances) of the respective bat species are presented.

Further information on the biology of spinturnicid mites are given and infestation characteristics are compared with those of other surveys.
