The Lucerne beetle Gonioctena fornicata (family Chrysomelidae) has been recorded for the German fauna for the first time in 2003. Gonioctena fornicata is one of twelve representatives of the genus in Germany, which are very similar to each other. Originally, the species is an element of the pontic fauna with xerothermic habitat requirements. Probably the species has been introduced to Baden-Württemberg with ship transports on river Rhine and its tributaries and is meanwhile established in the Upper Rhine valley. Adults and larvae of the 5 to 7 mm large species live on Lucerne (alfalfa, Medicago) and clover (Trifolium) and are classified as pests. In the US the species has been introduced several times with transports and is regarded as quarantine pest. (KR/CB)
