Abstract
Sawflies were collected in the northeast of the Czech Republic using Townes type Malaise traps. Traps were placed in eleven young Norway spruce (Picea abies) forests during the period from 1998 to 1999. Localities cover altitudes from 230 to 1,000 m a.s.l. In total, 285 species of Symphyta have been recently known from the study area (Xyelidae - 1, Pamphiliidae - 7, Argidae - 10, Cimbicidae - 3, Diprionidae - 5, Tenthredinidae - 252, Siricidae - 1, Xiphydriidae - 1, Cephidae - 5). The majority of the species have large distributional ranges and their host plants are forest tree species. Most of the sawflies were obtained from Malaise traps located in the young spruce stands, and therefore the silvicolous species prevail. Neodineura arquata represents a new genus and species and Heptamelus dahlbomi a new species for the fauna of the Czech Republic. Nine species have been classified as endangered and twenty-one species have been classified as vulnerable. Pristiphora robusta has been deleted from the list.
