Seven species new to science are described and their affinities discussed, viz.
Anopedias notaulatus (Finland), Inostemma koponeni (Finland and Poland),
Piestopleura canariensis (Canary Islands), Platygaster anopediana (Finland),
P. oblonga (Finland), Synopeas bialowiezaensis (Poland), and S. discoideus
(Finland).ThemalesofLeptacisbreisteiniBuhl,1997,L.corypheBuhl,1998,
