| abstract | Earlier published and newly determined Swiss moss mites belonging to the "ptychoid" groups are listed, discussed or described. From the 20 named species in the literature 10 are confirmed after critical discussion. New identifications of a total of 42 taxa are given, 3 of which (Phthiracarus besuchetianus sp.n., Steganacuars (S.) antennatus sp.n. and Steganacarus (S.) schweizeri sp.n.) are new to science and 30 new for the fauna of Switzerland. Some new or additional morphological data as well as some notes on the taxonomy and distribution of this group are given. |
