Zoogeographical analysis and statial distribution of auchenorrhynchs (Homoptera, Cicadina) in the Central Chernozem Region

A map of the biogeographical regionalization of the Central Chernozem Region (Lipetsk, Tambov, Kursk, Belgorod, and Voronezh provinces) is compiled based on the literature and the author's own collections of auchenorrhynchs. Ranges of all the species recorded from the region are given. Thirty nine types of the ranges classified in 13 groups are distinguished based on the distribution of Cicadina in the Palaearctic and in other biogeographical regions. A scheme of the statial distribution of auchenorrhynchs in the region is given. Twenty one types of stations are classified into seven types of a higher rank. The main zonal and azonal elements of the fauna were identified by comparative analysis of the species distribution between zoogeographical and statial groups. Connection between the distributional type of certain species and their habitat preferences was demonstrated.
