Small to medium-sized flies, body length 2.5-12 mm, slender to robust, varying in colour from yellow to black. Vibrissae absent, costa with subcostal break at some distance from the point of its confluence with R1, tibiae without dorsal preapical seta. Further details on the adult morphology are given by Iwasa (1998). The larvae are typically maggot-like, slender and smooth, anterior spiracle with species-specific lobes, and posterior spiracular plate with three elongate oval slits. More information about the larval morphology can be found in Iwasa (1998). The larvae are phytophagous, developing in various plants, in flowers of Daucaceae or even in fruits. Some species develop in wounds in trees or under bark.

Altogether 47 species are known to occur in Europe (Pape 2007); 37 are listed in the present checklist: 35 in the Czech Republic (34 in Bohemia, 31 in Moravia), and 34 in Slovakia. Since the ECV1, the number of species has not increased in either the Czech Republic or Slovakia. The species-richness of the psilid fauna is moderately well known in both the Czech Republic and Slovakia.

The basic characteristics of the family were given by Iwasa (1998). The Central Europen species may be identified using the classical monographs by Hennig (1941) or Stackelberg (1989), with more recent additions and corrections by  Carles-Tolrá (1993), Shatalkin (1986), Soós (1980, 1985) and Wang (1988). Recently, Shatalkin (1986) has revised the genera of Psilidae and has recognised only one genus, Psila. The nomenclature of the Fauna Europaea (Pape 2007) is used in this checklist.
