Abstract

The family Psilidae is reviewed for Switzerland and data are listed for all species currently known from this country. Chamaepsila sardoa (Rondani) and Ch. unilineata (Zetterstedt) are recorded for the first time from Switzerland. Psila (s. str.) helvetica sp. n. (Switzerland) and Chamaepsila confusa sp. n. (France, Switzerland) are described and illustrated. Keys for the European species of Psila s. str. Meigen and the Chamaepsila pallida group are provided. A summary of diagnostic characters of the genera of Psila s. lat. is given. An updated checklist of the 36 Swiss species is presented.
