Martin (Zoological Institute of the Cristian- Albre-chts-University of Kiel), Drs M. Grasshoff and U. Schreiber (Naturmuseum Senckenberg, Frankfurt-am-Main), and Dr. D. Tumanov (Zoological Insti-tute of RAS, St. Petersburg) for the opportunity to examine their water mite collections.

Annotation:

The idiosoma of deutonymphs and adult mites of the family Thermacaridae has 18 pairs of setae ( 2 - 2 - 4 - 4 - 6 - 4 - 4 - 4 - 2 - 4 - 0 ) and 5 pairs of lyriform organs. The idiosomal chaetotaxy of the family Thermacaridae and other groups of water mites is compared.
