Key for the separation of Halyomorpha halys (Stål) from similar-appearing pentatomids (Insecta: Heteroptera: Pentatomidae) occurring in Central Europe, with new Swiss records

Abstract

The introduced brown marmorated stink bug Halyomorpha halys (Stål, 1855) (Insecta, Heteroptera, Pen tatomidae) is superficially similar to several native European pentatomids. The present work pro - vides an identification key including photographs of all discussed pentatomid species. In Switzerland H. halys is now recorded not only from the canton Zürich, but also from Basel-Stadt, St. Gallen and Schaffhausen.
