Second addendum to the Leafhoppers and Planthoppers of Germany (Hemiptera: Auchenorrhyncha)

Abstract

This paper presents new faunistic and ecological data on 21 species of planthoppers and leafhoppers in Germany. Delphax armeniacus An., Javesella bottnica Huld., Micantulina teucrii (Cer.), Ficocyba ficaria (Horv.), Placotettix taeniatifrons (Kbm.), Allygidius furcatus (Ferr.), Phlogotettix cyclops (M. & R.) and Thamnotettix exemtus Mel. are new to the country. New distributional and ecological data are given for Megamelodes lequesnei W. Wg., Cercopis arcuata Fieb., Macropsis mulsanti (Fieb.), Dryodurgades antoniae (Mel.), Hishimonus hamatus Kuoh, Maiestas horvathi (Then), Anoplotettix fuscovenosus (Ferr.), Cicadula placida (Horv.), Ederranus discolor (J. Shlb.), Paralimnus lugens (Horv.), Psammotettix albomarginatus W. Wg., Pinumius areatus (St.l) and Cosmotettix evanescens Oss. An analysis of 28 species recorded as new for Germany in the last two decades showed that the increase is caused in equal shares by better taxonomic and faunistic knowledge on the one hand and real ecological changes through anthropogenic introductions and northward range expansions (presumably driven by climatic factors) on the other hand.
