ABSTRACT. Vibrational calling signals of 26 leafhopper species from the subfamilies Ulopinae, Ledrinae, Agalliinae, Xestocephalinae, Iassinae, Penthimiinae, Evacanthinae, and Deltocephalinae are described and illustrated by oscillograms and sonograms. Ledra auditura has nocturnal acoustic activity; males of all other species produce signals during daytime. Species rank of Iassus dorsalis is confirmed by signal analysis. Utecha trivia was recorded from Central European Russia, Maiestas oryzae — from Amur Oblast and Khabarovsk Krai for the first time; it is shown that records of Stymphalus rubrostriatus = Varta rubrostriata from the Russian Far East refer to Varta japonica. Examples of signal pattern similarity in different species are discussed. Both the type of frequency spectrum (noise or line) and signal temporal pattern bear phylogenetic information. Temporal pattern, compared to the frequency characteristics, is more exposed to the effect of natural selection resulting from competition for communication channels within insect communities. For this reason, it can be used in phylogenetic reconstructions only as an additional trait and by no means in all cases.

KEY WORDS: Homoptera, Auchenorrhyncha, Cicadellidae, vibrational communication, vibrational signals, new records, host plants.
