New and interesting true hoppers for the Netherlands (Homoptera: Cixiidae, Delphacidae & Cicadellidae)

Our knowledge on the Dutch true hopper fauna is growing. Since the most recent species list of 2011, 46 new species have been reported. In 2018-2020, four species were found new for the Netherlands: Hyalesthes obsolctus, Cicadclla lasiocarpae, Alcbra viridis and Kybos mucronatus. The presence of Idiocerus uicinus in the Netherlands is confirmed. Moreover, three species of which their distribution was restricted to the south of the province of Limburg, were discovered outside this region: Trigonocranus emmeae, Asiraca clauicornis and Errhomenus brachypterus. The xerothermophilic Neoaliturus/enestratus is rarely collected in the Netherlands, but showed an invasion in 2019-2020. The ecology and distribution of each species are discussed.
