Abstract

Im Rahmen der 21. Mitteleuropäischen Zikadentagung in Mueß bei Schwerin (Mecklenburg-Vorpommern, Deutschland) wurden Sammelexkursionen in ausgewählte Trockenrasen-, Küstendünen-, Salzwiesen- und Moorstandorte in der Umgebung von Schwerin durchgeführt. Insgesamt konnten in diesen Gebieten 134 Zikadenarten nachgewiesen werden, davon 52 Arten der Roten Liste. Die Zikadenarten Doratura exilis Horv. 1903 und Kelisia minima Rib., 1934 waren neu für das Gebiet um Schwerin.

Leafhoppers and planthoppers of selected dry grasslands, coastal dunes, salt marshes, peat bogs and fens in the vicinity of Schwerin (Mecklenburg-Vorpommern) (Hemiptera: Auchenorrhyncha). – On the occasion of the 21th Central European Auchenorrhyncha meet- ing 2014, held from 11 until 14 July 2014 in Mueß/ Schwerin (Germany), field excursions to selected dry meadows, coastal dunes, salt marshes, peat bogs and fens in the vicinity of Schwerin (Mecklenburg) were made. In total, 134 species including 52 species of the Red List of Germany were recorded. Most remarkable were Kelisia minima Rib., a rare species mostly confined to saltmarshes and known worldwide only from about 10 localities, Macropsidius sahlbergi (Fl.), a species that became almost extinct all over central Europe during recent decades and which was closely associated with ants on the Petersberg, Psammotettix maritimus (Perr.), which was new to the whole Baltic Sea region, and Doratura littoralis Kuntze, a rare and localized endemic of the southern Baltic coast. Another remarkable species is Cosmotettix evanescens Oss. which was recorded not on this excursion, but in 2011 in the Grambower Moor. This species was formerly only known from southern Sweden and southern Finnland.
